Changelog

Unreleased

0.19.2 - 2026-07-31

  • Reveal commits are retry-safe after DOM or scheduler failures: failed patches can reuse their sequence, buffered siblings remain queued, and failed recovery keeps the settled-error marker until the replacement commits.
  • Completion failures reject only their own waiter without dropping sibling work. Loader-owned, unobserved frame commits enter structured error reporting exactly once, while observed commits and injected schedulers retain their existing error ownership.
  • Signal refs now retain registry provenance for inline bindings and ifChanged snapshots. Same-id refs from separate registries subscribe and compare independently, including composite bindings and legacy refs.
  • Removing an outer boundary now releases inline binding ids owned by nested boundaries instead of leaving stale values reachable by later scans.
  • Updated the Framework integration to @async/flow 0.10.6.
  • Refreshed the two streaming scenario budgets to 48,000 B after the reviewed recovery and ownership fixes; current closures are 47,613 B and 47,679 B gzip.
  • Bundle size from bundled TypeScript source: browser.ts raw 281,608 B (281.6 KB / 0.282 MB), gzip 57,605 B (57.6 KB / 0.058 MB), br 47,220 B (47.2 KB / 0.047 MB) -> browser.min.js raw 115,320 B (115.3 KB / 0.115 MB), gzip 34,608 B (34.6 KB / 0.035 MB), br 30,437 B (30.4 KB / 0.030 MB); delta raw -166,288 B (-166.3 KB / -0.166 MB), gzip -22,997 B (-23.0 KB / -0.023 MB), br -16,783 B (-16.8 KB / -0.017 MB).

0.19.1 - 2026-07-31

  • Fixed pre-runtime app.applySnapshot(...): snapshots without a flow key no longer throw, and snapshot browser-cache entries now reach the first runtime instead of being dropped.
  • Unified the reveal vocabulary in src/reveal-policy.js, shared by the boundary receiver and the build optimizer. The receiver now accepts the optimizer's default tail visible (normalized to "no tail treatment") instead of throwing.
  • AsyncStream patches resolved through a runtime or loader now share one receiver per loader, so sequence dedup and reveal buffering work across inline stream scripts.
  • Errored patches carrying reveal metadata settle their reveal index so ordered and together groups commit buffered siblings instead of stalling forever.
  • applyServerResult no longer blanks a boundary for envelopes with html: undefined or status: 204, matching the router's swap accounting; the router now shares the exported isServerEnvelope predicate instead of a drifted truthy wire-key check.
  • Bare * route segments compile as anonymous rest splats (previously scored as wildcards but compiled as the literal character *).
  • signal:class:x now delegates to the shared class-token writer, removing a binding-key collision with class:x that silently dropped one of the two bindings.
  • Expired server-route prefetch entries are swept on insert instead of accumulating for the router's lifetime.
  • Removed dead code that duplicated live implementations: parsePath in signals.js, isAsyncSignalSnapshot in app.js, and a no-op template branch in the loader's swap HTML renderer.
  • Centralized the typed-registry CRUD scaffolding (createTypedRegistryMethods in registry-store.js): the handler, partial, component, cache, and server registries now share one register/registerMany/unregister/_adoptMany implementation instead of five drifting copies. Route and signal registries stay custom by design.
  • Replaced the three hand-rolled pending facades in app.js (loader, router, router-loader) with one createPendingFacade implementation; per-facade differences (commit-await methods, _clearCurrent batch clearing) are now explicit options.
  • Extracted shared DOM helpers into src/dom-utils.js (element walking, boundary lookup, toFragment): the boundary receiver now uses the loader's TreeWalker walk instead of querySelectorAll("*"), and the receiver-vs-loader clone/adopt fork is an explicit clone option.
  • One owner for repeated micro-implementations: mergeFeatures (app.js createAppFeatureSet, previously copied byte-identical into three entry files), the component fragment comment-marker protocol (html.js, built by components and parsed by the loader), lazy-descriptor invocation (createLazyInvoker in lazy-registry.js, adopted by handlers, partials, components, and async signals), toError/errorMessage/reportUnhandled (errors.js, adopted by server, router, and the scheduler), and script-JSON plus attribute escaping (html.js, adopted by app.js SSR output). boundary-receiver.js and lazy-registry.js keep deliberately-commented local copies of toError/errorMessage so the stream slice stays free of the errors.js module.
  • Derived flow bridges (async-signal loading/error/ready/status/ version metadata and computed refs) no longer serialize into page snapshots: they recompute on resume, and the .error metadata bridge previously embedded raw error objects in the page payload.
  • Fixed the inline swap-binding lifecycle: comparison renders (ifChanged, bind, swap-many snapshots) serialize binding values to stable tokens instead of minting registry ids — per-render ids embedded in snapshots made every comparison unequal, silently degrading dedupe to always-swap — and a boundary's committed render now tracks its minted ids and releases the previous content's ids on re-swap, so repeated swaps no longer grow the binding map for the loader's lifetime.
  • Owned schedulers (constructed by Loader and createApp) report job failures through the structured error pipeline: bindings, commits, and effects that fail now reach the configured onError and dispatch a cancelable async:error event on the job's element scope, instead of escaping straight to globalThis.reportError. Injected schedulers keep their creator's error wiring.
  • detachRoot(null) destroys a supplied loader that never registered into the root set (detach before start()), mirroring the guard destroy() already had.
  • Rendering an inline template binding without a Loader now throws the same clear error the component renderer raises, instead of silently emitting [object Object] into the attribute.
  • Completion and recovery hardening: completion jobs (awaited commits) reject their awaiter without double-reporting through the scheduler onError bridge; inline binding comparison tokens JSON-escape keys and leaves so differently-shaped values cannot collide into a skipped swap; a content retry now recovers an error-settled reveal index instead of rejecting as a double commit; the router facade restores the original ready()-resolution order; the registry store's introspection snapshot honors _snapshotExempt; the app-owned scheduler bridge reads runtime.onError at failure time.
  • Examples: the router example gains a "*" fallback route (first render no longer errors on the served URL); the ssr example resumes through the public readSnapshot(document) API; the streaming example now actually streams — out-of-order inline wire patches through AsyncStream.applyScript with reveal ordering, error settling, and recovery; new swap-dedupe example for ifChanged; partials README documents the runtime-capture pattern.
  • Production tests: a server-render → JSON wire → readSnapshot browser resume round trip (no partial, server function, or re-render on the browser side), and a progressive-document streaming flow (shuffled inline patches, buffering, error settle, recovery) run as part of the server and runtime suites.
  • Removed the dead scripts/release-doctor.js (superseded by async-pipeline release doctor); the examples scripts run the whole tests/examples/ suite; fixed the stale benchmarks/results/ ignore rule; stream scenario budgets carry working headroom (47500).
  • Updated the inlined Flow integration to @async/flow 0.10.5 for resume-safe async-signal snapshots and cross-copy compose stops.
  • Bundle size from bundled TypeScript source: browser.ts raw 279,370 B (279.4 KB / 0.279 MB), gzip 56,946 B (56.9 KB / 0.057 MB), br 46,741 B (46.7 KB / 0.047 MB) -> browser.min.js raw 114,724 B (114.7 KB / 0.115 MB), gzip 34,458 B (34.5 KB / 0.034 MB), br 30,253 B (30.3 KB / 0.030 MB); delta raw -164,646 B (-164.6 KB / -0.165 MB), gzip -22,488 B (-22.5 KB / -0.022 MB), br -16,488 B (-16.5 KB / -0.016 MB).

0.19.0 - 2026-07-21

  • Added structured runtime diagnostics with stable error codes, AsyncError, toAsyncDiagnostic(...), and onError ownership across apps, loaders, and routers. Delegated and lifecycle failures now reach callbacks, cancelable async:error events, or the platform unhandled-error path instead of disappearing.
  • Published the framework-native app authoring contract as package AGENTS.md, added declarative component and app-composition examples, and added a repository gate that keeps public examples on framework-owned attachment, events, bindings, and boundary updates.
  • Updated @async/flow to 0.10.4 and documented the Flow boundary: live Flow declarations materialize into ordinary framework registries, while portable machine plans remain optimizer input and do not introduce a separate runtime interpreter or slice.
  • Bundle size from bundled TypeScript source: browser.ts raw 271,362 B (271.4 KB / 0.271 MB), gzip 52,388 B (52.4 KB / 0.052 MB), br 42,937 B (42.9 KB / 0.043 MB) -> browser.min.js raw 113,880 B (113.9 KB / 0.114 MB), gzip 33,597 B (33.6 KB / 0.034 MB), br 29,462 B (29.5 KB / 0.029 MB); delta raw -157,482 B (-157.5 KB / -0.157 MB), gzip -18,791 B (-18.8 KB / -0.019 MB), br -13,475 B (-13.5 KB / -0.013 MB).

0.18.1 - 2026-07-09

  • Reorganized the README into a compact guide and moved the deeper material into focused docs for install/load, app registries, server calls, SSR activation, streaming boundaries, entrypoints, and Vite/Hono setup.
  • Updated the layer docs and specs to use L0-L7 abstraction layers consistently, including clearer L0 server-led HTML, native forms/actions, and optional enhancement boundaries.
  • Added examples/hateoas-actions: a Hono-rendered HATEOAS account flow where links and native form verbs remain the source of truth, while Async enhances the returned fragments into async:boundary swaps.
  • Bundle size from bundled TypeScript source: browser.ts raw 261,003 B (261.0 KB / 0.261 MB), gzip 49,799 B (49.8 KB / 0.050 MB), br 41,084 B (41.1 KB / 0.041 MB) -> browser.min.js raw 108,690 B (108.7 KB / 0.109 MB), gzip 31,875 B (31.9 KB / 0.032 MB), br 28,013 B (28.0 KB / 0.028 MB); delta raw -152,313 B (-152.3 KB / -0.152 MB), gzip -17,924 B (-17.9 KB / -0.018 MB), br -13,071 B (-13.1 KB / -0.013 MB).

0.18.0 - 2026-07-08

  • BREAKING: unified lifecycle vocabulary on "attach" and removed the "mount" term everywhere. loader.mount(...) and the Async.loader.mount(...) facade are now loader.attach(...) / Async.loader.attach(...); the rendered-component mount(target) alias is gone (use attach(target)); this.on("mount", ...) now throws (use this.on("attach", ...)) and the this.onMount(...) helper was removed (use this.onAttach(...)); the on:mount markup alias no longer binds; stale markup logs a one-time removal warning. The Flow bridge feature key mountRegistrations is now attachRegistrations (attachFlowRegistrations). Specs, docs, and type declarations use attach terminology throughout.
  • Bundle size from bundled TypeScript source: browser.ts raw 261,003 B (261.0 KB / 0.261 MB), gzip 49,799 B (49.8 KB / 0.050 MB), br 41,084 B (41.1 KB / 0.041 MB) -> browser.min.js raw 108,690 B (108.7 KB / 0.109 MB), gzip 31,875 B (31.9 KB / 0.032 MB), br 28,013 B (28.0 KB / 0.028 MB); delta raw -152,313 B (-152.3 KB / -0.152 MB), gzip -17,924 B (-17.9 KB / -0.018 MB), br -13,071 B (-13.1 KB / -0.013 MB).

0.17.0 - 2026-07-08

  • Memoized boundary-element lookup in the loader: loader.swap(...) resolved its boundary id by walking the entire document on every swap (visible as a full-document traversal per History selection); the element is now cached weakly per id and re-resolved only when it leaves the document or loses its boundary id.
  • Activation now scans a scope with a single tree traversal: pseudo-event dispatch (attach/visible/intersect) reuses the shared element collection instead of a second walk. Component-mounted children keep their own nested scan.
  • The Vite plugin excludes the framework entrypoints from optimizeDeps (opt out with optimizeFrameworkDeps: true): the published entrypoints are flat ESM bundles, and Vite's prebundle cache does not watch file:/link: dependency contents — local framework rebuilds were served stale until node_modules/.vite was deleted by hand.
  • Navigation failures from intercepted links, forms, and history events are now logged with console.error (they have no caller to reject to), and unmatched navigation without fallback: "document" logs a console.warn with guidance — previously both failed silently.
  • Added a commit stall watchdog: loader._whenCommitted(...) warns (commitStallWarningMs, default 2000ms, 0/false disables) when a boundary commit has not settled, naming the await-inside-scheduler.batch deadlock composition so it is diagnosable instead of a silent freeze.
  • router.prefetch(...) on server: true routes now caches the fetched envelope briefly (prefetchTtlMs option, default 5000ms); the next navigation with a matching URL and boundary consumes it single-use instead of refetching.
  • Added tests/performance/: deterministic hot-path performance contracts (activation scan traversal counts, attribute-config memoization, swap rescan scoping, scheduler/signal write coalescing, single frame wait per commit batch, router fast-path work counts) plus a hot-path registry (tests/performance/hot-paths.json). A coverage guardrail keeps the registry, the // @hot-paths: headers in contract tests, and the test.performance pipeline task inputs in sync, so changes to a registered hot-path source automatically re-run the suite. The swap-rescan contracts caught the boundary-lookup walk fixed above.
  • Categorized the test tree into suites — tests/unit/, tests/runtime/, tests/router/, tests/server/, tests/timing/, tests/performance/, tests/build/, and tests/examples/ — with matching test:<suite> scripts (see tests/README.md). Added a dedicated tests/timing/ suite covering rendering and requestAnimationFrame gotchas under explicit frame-timed schedulers: suspended-frame fallbacks, exactly-once frame/fallback races, FIFO commit ordering, commits scheduled inside open batches, loader swaps with rebinding and ordering, handler-initiated swaps, signal/swap coalescing, and router navigation (local partials, server partials with sub-boundaries, suspended frames, popstate).
  • Bundle size from bundled TypeScript source: browser.ts raw 261,577 B (261.6 KB / 0.262 MB), gzip 50,018 B (50.0 KB / 0.050 MB), br 41,211 B (41.2 KB / 0.041 MB) -> browser.min.js raw 108,975 B (109.0 KB / 0.109 MB), gzip 32,004 B (32.0 KB / 0.032 MB), br 28,111 B (28.1 KB / 0.028 MB); delta raw -152,602 B (-152.6 KB / -0.153 MB), gzip -18,014 B (-18.0 KB / -0.018 MB), br -13,100 B (-13.1 KB / -0.013 MB).

0.16.0 - 2026-07-08

  • Added server route partials: defineRoute({ server: true }) makes CSR/SPA navigation fetch the target URL with Accept: application/x-async-partial (plus an x-async-boundary request header naming the boundary the transition plan wants filled) and apply the returned wire server envelope ({ __async_server_result__: 1, html, signals, cache, boundary, redirect, title }) through the existing navigation pipeline. HTTP redirects followed by the fetch update router state, the route snapshot, and browser history to the final URL. createRouter(...) accepts a fetch option to override the window fetch (tests, custom transports); ambient globalThis.fetch is never used. prefetch(...) returns the fetched envelope without applying it.
  • Added a router fallback option ("error" default, "document"): with fallback: "document", unmatched navigation in client modes performs native document navigation instead of dead-ending in router.error, enabling incremental SPA adoption over server-rendered apps. Assigning the current browser URL is refused to prevent reload loops. Server-partial responses that are not envelopes (or fail) also fall back to document navigation in this mode.
  • Added render: "document" route definitions: matched routes can force native document navigation (downloads, raw endpoints) while staying registered.
  • Added multi-segment splat patterns: /:org/:name/tree/*rest captures the remaining segments (decoded per segment) as params.rest. Splat segments must terminate the pattern and rank above * wildcard routes and below single-segment params.
  • Added master-detail navigation: viewKey may now be a function of the route match, and routes may declare subBoundary. A same-view navigation (same computed viewKey) on a route with subBoundary renders/fetches into that nested boundary instead of going state-only, so query-driven detail panes (e.g. ?commit=<sha>) swap without touching the surrounding view. Route snapshots keep comparing view identity on the route-level boundary.
  • Partial results with a string title now update document.title, and client navigations that swapped content scroll to the top (or to the URL hash target) unless the router is created with scroll: false.
  • Async.start(...) now forwards urlMode, fallback, and scroll to the runtime router and accepts a routerOptions object for the remaining createRouter(...) options.
  • Server runtime render(url, { document: false }) returns the raw route fragment without the boundary section or snapshot script, for building server route partial envelopes whose swap target is an already-activated document.
  • Fixed a navigation deadlock in CSR/SPA modes with frame-timed commits (real browsers): applyNavigationResult awaited boundary commit completion inside scheduler.batch(...), where automatic flushes are suppressed, so route swaps could stall indefinitely and never update document.title, history, or router.pending. Commit awaits now happen outside the batch. Node test environments commit synchronously, which is why the suite never caught it; new regression tests force frame timing.
  • Frame-timed commits now race the animation frame against a timeout (frameFallbackMs, default 50ms): browsers suspend requestAnimationFrame in hidden tabs, which froze boundary commits — and anything awaiting them, including router navigation — until the tab became visible again. Visible tabs stay frame-aligned; hidden tabs fall back to timer cadence.
  • Bundle size from bundled TypeScript source: browser.ts raw 259,693 B (259.7 KB / 0.260 MB), gzip 49,336 B (49.3 KB / 0.049 MB), br 40,621 B (40.6 KB / 0.041 MB) -> browser.min.js raw 108,501 B (108.5 KB / 0.109 MB), gzip 31,770 B (31.8 KB / 0.032 MB), br 27,913 B (27.9 KB / 0.028 MB); delta raw -151,192 B (-151.2 KB / -0.151 MB), gzip -17,566 B (-17.6 KB / -0.018 MB), br -12,708 B (-12.7 KB / -0.013 MB).

0.15.3 - 2026-07-06

  • Memoized attribute-prefix normalization by config identity so activation scans reuse normalized attribute config on the hot path instead of re-normalizing prefixes for every attribute read.
  • Reworked loader activation to collect each scan scope once with a TreeWalker, share that element list across revive, signal, class, event, boundary, and component passes, and merge attach, visible, and intersect pseudo-event binding into one pass.
  • Bundle size from bundled TypeScript source: browser.ts raw 258,315 B (258.3 KB / 0.258 MB), gzip 48,822 B (48.8 KB / 0.049 MB), br 40,208 B (40.2 KB / 0.040 MB) -> browser.min.js raw 108,261 B (108.3 KB / 0.108 MB), gzip 31,669 B (31.7 KB / 0.032 MB), br 27,814 B (27.8 KB / 0.028 MB); delta raw -150,054 B (-150.1 KB / -0.150 MB), gzip -17,153 B (-17.2 KB / -0.017 MB), br -12,394 B (-12.4 KB / -0.012 MB).

0.15.2 - 2026-07-06

  • Expanded @async/framework/flow (and the main entry) to re-export the complete @async/flow helper surface: step helpers (dispatch, after, branch, guard, transition), condition helpers (bool, every, some, not, can, matches, inspect), composition (compose, parallel, remember), and the flowStatus declaration helper, alongside the existing set, update, when, and onError. Apps can author full Flow definitions without installing @async/flow directly.
  • Removed the per-notification random dedupe key from the Flow scheduler bridge. Keys added keyed-job bookkeeping for every Flow notification without ever deduping, and a key collision could silently drop a notification.
  • Dropped the stale @async/flow/run module mapping from the bundle scripts (@async/flow/run is not a public Flow subpath) and added the @async/flow/compose mapping used by the expanded flow entry.

0.15.1 - 2026-07-06

  • Updated the Flow bridge to consume @async/flow 0.10.3, including the framework-runtime helper paths required by current Flow releases.
  • Fixed Flow async signal refresh handlers so a refresh without authored input uses the signal's configured arguments instead of passing an empty object.
  • Rolled back partial signal and handler registrations when a Flow mount fails, preventing failed mounts from leaving stale registry entries behind.
  • Fixed SSR signal patches for mounted Flow signals so exact paths such as cart.total update without serializing an unintended parent cart signal.
  • Added ./jsx/jsx-runtime and ./jsx/jsx-dev-runtime package exports so jsxImportSource: "@async/framework/jsx" resolves under the automatic JSX transform; the base entrypoints default to the runtime profile types.
  • Guarded the Vite plugin bootstrap transform: modules are replaced only when they actually import @async/framework/jsx* (comment and string mentions no longer match), replacements are logged, multiple modules collapsed into one virtual bootstrap now warn, and full-rewrite transforms return an empty sourcemap instead of map: null.
  • Made the Vite 8 + Rolldown host check use plugin-context metadata (this.meta.viteVersion / this.meta.rolldownVersion) in configResolved instead of treating the resolved config as a host descriptor, and exported detectViteHost and importsAsyncJsx helpers.
  • Stopped defaulting server.base when composing @hono/vite-dev-server; base is forwarded only when the app sets it, so user-configured Vite base values are no longer overridden by default.
  • Declared vite >= 8 as an optional peer dependency.
  • Reported runtime slice status (available for signals/events, planned for async-signals/stream) with a runtime-slice-planned warning diagnostic, and documented that planned slices are recorded but not activated by @async/framework/runtime yet.
  • Reworked the vite-jsx-streaming example onto the buildtime JSX profile so the authoring source matches the shipped type profiles, and documented that the fixture profile is the current source of truth for the emitted plan.

0.15.0 - 2026-06-26

  • Added scheduler commit-phase ordering for app-level loader swaps and streamed boundary patches, including frame-backed commits and deterministic non-browser fallbacks.
  • Added declaration conventions for Async.use(...) so registered kinds can materialize on register, start, or demand under configurable duplicate policies.
  • Bundle size from bundled TypeScript source: browser.ts raw 255,782 B (255.8 KB / 0.256 MB), gzip 47,724 B (47.7 KB / 0.048 MB), br 39,343 B (39.3 KB / 0.039 MB) -> browser.min.js raw 107,826 B (107.8 KB / 0.108 MB), gzip 31,527 B (31.5 KB / 0.032 MB), br 27,717 B (27.7 KB / 0.028 MB); delta raw -147,956 B (-148.0 KB / -0.148 MB), gzip -16,197 B (-16.2 KB / -0.016 MB), br -11,626 B (-11.6 KB / -0.012 MB).

0.14.0 - 2026-06-26

  • Updated the Flow bridge to consume @async/flow 0.10.0 through the scheduler-free integration subpaths and shared protocol brands.
  • Bundle size from bundled TypeScript source: browser.ts raw 236,170 B (236.2 KB / 0.236 MB), gzip 44,028 B (44.0 KB / 0.044 MB), br 36,421 B (36.4 KB / 0.036 MB) -> browser.min.js raw 99,320 B (99.3 KB / 0.099 MB), gzip 29,136 B (29.1 KB / 0.029 MB), br 25,662 B (25.7 KB / 0.026 MB); delta raw -136,850 B (-136.9 KB / -0.137 MB), gzip -14,892 B (-14.9 KB / -0.015 MB), br -10,759 B (-10.8 KB / -0.011 MB).

0.13.0 - 2026-06-26

  • Moved streaming, Flow, and router browser code behind explicit @async/framework/stream, @async/framework/flow, and @async/framework/router subpaths so the default browser asset stays focused on the core runtime.
  • Added guarded Flow and router startup errors when default-browser apps use those declarations without importing their opt-in subpath.
  • Added a bundle optimizer pipeline for Brotli-oriented candidate measurement and diagnostics.
  • Bundle size from bundled TypeScript source: browser.ts raw 227,580 B (227.6 KB / 0.228 MB), gzip 42,303 B (42.3 KB / 0.042 MB), br 35,028 B (35.0 KB / 0.035 MB) -> browser.min.js raw 95,660 B (95.7 KB / 0.096 MB), gzip 27,847 B (27.8 KB / 0.028 MB), br 24,709 B (24.7 KB / 0.025 MB); delta raw -131,920 B (-131.9 KB / -0.132 MB), gzip -14,456 B (-14.5 KB / -0.014 MB), br -10,319 B (-10.3 KB / -0.010 MB).

0.12.6 - 2026-06-24

  • Added the app-level Async.router facade with queued navigate, prefetch, ready, match, and nested loader access before runtime startup.
  • Added router transition planning that skips duplicate active-route work and uses signal-only updates for same-view navigation unless force: true is requested.
  • Made createRouter(...) start immediately, rejected separate signal registry injection, and kept route and partial registration on the app registry path.
  • Documented routing layers from simple Async.use({ route, partial }) setup through signal-router dashboards, refresh scopes, and custom runtime wiring.
  • Bundle size from bundled TypeScript source: browser.ts raw 366,552 B (366.6 KB / 0.367 MB), gzip 67,930 B (67.9 KB / 0.068 MB), br 55,263 B (55.3 KB / 0.055 MB) -> browser.min.js raw 153,961 B (154.0 KB / 0.154 MB), gzip 44,479 B (44.5 KB / 0.044 MB), br 38,561 B (38.6 KB / 0.039 MB); delta raw -212,591 B (-212.6 KB / -0.213 MB), gzip -23,451 B (-23.5 KB / -0.023 MB), br -16,702 B (-16.7 KB / -0.017 MB).

0.12.5 - 2026-06-24

  • Added asyncFramework({ layer, server, client }) for Hono-backed Vite development and client-only production asset builds without a platform target.
  • Added Vite Hono and Vite JSX streaming examples, including optimizer report visibility for the selected signals, events, async-signals, and stream runtime slices.
  • Re-exported the optimizer report from Vite-generated JSX bootstrap modules and marked runtime handler imports for Vite analysis so example dev servers stay warning-free.
  • Bundle size from bundled TypeScript source: browser.ts raw 356,171 B (356.2 KB / 0.356 MB), gzip 66,646 B (66.6 KB / 0.067 MB), br 54,356 B (54.4 KB / 0.054 MB) -> browser.min.js raw 149,871 B (149.9 KB / 0.150 MB), gzip 43,590 B (43.6 KB / 0.044 MB), br 37,839 B (37.8 KB / 0.038 MB); delta raw -206,300 B (-206.3 KB / -0.206 MB), gzip -23,056 B (-23.1 KB / -0.023 MB), br -16,517 B (-16.5 KB / -0.017 MB).

0.12.4 - 2026-06-24

  • Added loader.swap({ type: "many", ifChanged: true }) to skip unchanged per-boundary replacement inside batched swaps.
  • Added loader.defineRefreshPlan(...) and loader.refresh(scope) for declarative scope-to-boundary refresh orchestration in signal-router SPAs.
  • Added loader.swap({ type: "bind", deps: [...] }) for explicit signal-path refresh dependencies instead of implicit render-time collection.
  • Added per-entry { html, strategy, attach } objects in type: "many" updates for mixed morph/replace batches.
  • Added morph attach: "preserve" (default) and attach: "rebind" options, plus a development warning when morph preserves an on:attach node but removes listener-bearing descendants.

0.12.3 - 2026-06-24

  • Treat route partials that return status: 204, no html key, bare null, or bare undefined as no-op route HTML updates instead of clearing or stringifying the active boundary.
  • Added config-first loader.swap({ type }) variants for unchanged-aware, batched, and signal-bound boundary refreshes without expanding the loader method surface.
  • Bundle size from bundled TypeScript source: browser.ts raw 348,555 B (348.6 KB / 0.349 MB), gzip 65,264 B (65.3 KB / 0.065 MB), br 53,133 B (53.1 KB / 0.053 MB) -> browser.min.js raw 146,383 B (146.4 KB / 0.146 MB), gzip 42,600 B (42.6 KB / 0.043 MB), br 37,056 B (37.1 KB / 0.037 MB); delta raw -202,172 B (-202.2 KB / -0.202 MB), gzip -22,664 B (-22.7 KB / -0.023 MB), br -16,077 B (-16.1 KB / -0.016 MB).

0.12.2 - 2026-06-24

  • Added createRouter({ mode: "signals" }) for route-only shells that update router.* state and history without rendering partials or swapping boundaries.
  • Added loader.swap(boundary, html, { scan }) with auto, full, and none scan modes for cheaper boundary replacement when inserted content is inert or manually scanned later.
  • Added loader.swap(boundary, html, { strategy: "morph" }) as an opt-in stable-shell update path that preserves matching nodes, avoids full subtree replacement, and still cleans removed or replaced scoped resources.
  • Treat partial envelopes with html: undefined as no route replacement and warn instead of clearing the active route boundary; html: "" remains an explicit clear.
  • Scoped lifecycle fallback hooks for components rendered through this.render(...) so this.onMount(...), this.onVisible(...), and this.on("intersect", ...) target the child component's rendered root instead of the ancestor mount root.
  • Preserved direct loader.mount(target, Component) fallback behavior, where rootless and multi-root top-level components still receive the mount target.
  • Updated the bundled Flow bridge to @async/flow@0.5.0, using async signal detection while preserving existing async signal metadata and refresh paths.
  • Migration note: code that intentionally used nested fallback hooks to mutate the ancestor mount root should move that behavior to the ancestor component or bind a specific element with on:attach.
  • Added this.onAttach(fn) as the canonical component attach lifecycle helper, with this.onMount(fn), this.on("mount", ...), and on:mount retained as compatibility aliases that warn about the rename.

0.11.29 - 2026-06-21

  • Added the Markdown-backed GitHub Pages docs app with hash routes, command search, grouped navigation, article content, and an on-page heading rail.
  • Added createRouter({ urlMode: "hash" }) for static-host routes such as #/docs/getting-started while preserving ordinary section anchors.
  • Added publish-package types and source metadata for API indexers while preserving the existing export-map declarations.
  • Renamed build optimizer signal source output from derived and async to the public-facing computed and asyncSignal intent names.
  • Kept event normalization ahead of signal classification and runtime-slice selection in the optimizer artifact order.
  • Updated optimizer artifact, runtime selection, build profile, and signal classification tests to prove computed and async signal reporting, ownership diagnostics, maybe-promise rejection, runtime slice selection, and bootstrap report parity.

0.11.28 - 2026-06-21

  • Added a profile-aware event normalization artifact before signal classification so JSX-native event props and protocol event props lower to canonical on: event records.
  • Preserved source event prop spelling in optimizer diagnostics while accepting protocol event props only for runtime or compatibility profiles.
  • Added duplicate canonical event diagnostics so mixed onClick and on:click declarations cannot silently overwrite each other.

0.11.27 - 2026-06-21

  • Added the composition pattern catalog covering default children, named regions, scoped content templates, presenter component props, dynamic outlets, boundaries, and anti-patterns.
  • Separated L1 and L2 examples for each composition pattern and marked planned source forms so released behavior is distinct from future build-required syntax.
  • Added out-of-order streaming guidance for every composition pattern, including boundary placement, independent commits, same-boundary sequencing, and rescanning inserted streamed HTML.

0.11.26 - 2026-06-21

  • Added a build-optimizer children-fragment lowering artifact for JSX nested children, recording empty, static, and lazy fragment output without retaining production JSX node arrays.
  • Added diagnostics for authored children props, mixed explicit and nested children sources, runtime JSX children arrays, and unknown child-fragment resourcefulness before optimizer output is trusted.

0.11.25 - 2026-06-21

  • Added explicit <template async:children> capture for registered async:component hosts, passing captured content through the same scoped default-children fragment contract as this.render(...).
  • Added loader coverage proving explicit template children render only when consumed, ordinary host content is not implicitly captured, inserted protocol attributes are rescanned, and invalid or duplicate children templates fail.
  • Documented the no-build template children contract in the README, DOM protocol spec, and component-system spec.

0.11.24 - 2026-06-21

  • Added scoped default children fragments for this.render(Component, props, children), including lazy children factories, single-consumption checks, and duplicate source validation.
  • Added component tests proving static children, lazy nested component children, escaped string children, duplicate children errors, and cleanup for handlers and signals created while rendering children.
  • Updated framework declarations and type fixtures so components can type optional Children props while callers use the third render argument instead of authoring props.children.

0.11.23 - 2026-06-21

  • Added first-class JSX type profiles for runtime/no-build and buildtime/build-required authoring, including profile-local automatic jsx-runtime and jsx-dev-runtime package subpaths.
  • Added TypeScript fixtures proving runtime JSX accepts protocol attributes, strict buildtime JSX rejects protocol props, and both profiles avoid global ambient JSX pollution.
  • Added component registry mounting through async:component plus this.slot(...) outlets for child component replacement from signal-derived props.
  • Added example README coverage and clarified benchmark smoke checks without publishing an incomplete Vite optimizer setup as a public example.

0.11.22 - 2026-06-19

  • Updated framework release automation to consume @async/pipeline@0.9.25, whose generated release workflow runs package-owned release evidence before release plan/inspect/changelog/notes steps so dist/ exists before package inspection.

0.11.19 - 2026-06-19

  • Added the first build-required profile subpaths, @async/framework/jsx and @async/framework/vite, with package export, declaration, pack, and installed-package coverage.
  • Added JSX authoring markers for signal, component, Suspense, and Reveal that stay inert for compiler analysis instead of executing app code.
  • Added a Vite 8+ Rolldown plugin spike that emits a deterministic virtual runtime plan/report from fixture metadata and rejects unsupported hosts before transform output is trusted.

  • Added generated package artifacts and installed-package coverage for runtime slice subpaths.
  • Added deterministic scenario-size fixtures and checks for runtime, router, server-call, and boundary receiver examples.

0.11.15 - 2026-06-19

  • Made the source package private and kept its public surface to the minimal export spec for root, /browser, /server, and /package.json only.
  • Moved publish staging to generated dist/package.json so npm and release automation publish from dist/ while package consumers still receive root-level artifacts without dist/ paths.
  • Removed legacy direct artifact subpath exports plus top-level main/module/browser/types and generated file lists from the source manifest.
  • Updated pack, size, pipeline, and installed-package coverage to verify the browser and server entrypoints remain split after packing.

  • Added declarative on:intersect with intersect:threshold, intersect:root-margin, and intersect:once pseudo-event options, including custom intersect attribute prefix support.
  • Added observer cleanup coverage for component teardown, boundary swaps, fallback scheduling, repeated entries, and existing visible compatibility.
  • Moved root release artifacts to an ignored generated-output workflow: tests, bundle checks, pack checks, and generated CI tasks materialize the current package surface before verification or publish.
  • Bundle size from bundled TypeScript source: browser.ts 197,173 B raw / 37,198 B gzip -> browser.min.js 84,013 B raw / 24,894 B gzip (-113,160 B raw, -12,304 B gzip).

  • Validated server proxy arguments, default input payloads, and selected signal values against an explicit JSON transport model before requests leave the caller.
  • Rejected values that JSON.stringify would silently corrupt, including undefined, non-finite numbers, functions, symbols, sparse arrays, circular structures, class instances, dates, maps, sets, buffers, streams, and web platform request/body objects.
  • Added path-aware regression coverage for invalid transport values and documented the supported server-call JSON model.
  • Bundle size from bundled TypeScript source: browser.ts 187,564 B raw / 35,332 B gzip -> browser.min.js 80,009 B raw / 23,677 B gzip (-107,555 B raw, -11,655 B gzip).

0.11.12 - 2026-06-18

  • Deferred boundary receiver sequence commits until patch effects complete so failed DOM swaps, scheduler flushes, redirects, or missing capabilities no longer make the same streamed sequence stale.
  • Serialized same-boundary patch application to keep concurrent patches from committing out of order while preserving stale rejection after successful commits.
  • Added regression coverage for retryable DOM, scheduler, redirect, and capability failures plus idempotent partial-effect replay.
  • Bundle size from bundled TypeScript source: browser.ts 186,064 B raw / 35,039 B gzip -> browser.min.js 79,042 B raw / 23,445 B gzip (-107,022 B raw, -11,594 B gzip).

0.11.11 - 2026-06-18

  • Serialized rejected async-signal snapshot errors to stable name, message, and code records so JSON SSR snapshots preserve documented $error.message bindings during browser activation.
  • Normalized non-Error rejections into readable error records while omitting arbitrary error object properties from snapshots by default.
  • Added regression coverage for JSON snapshot round-trips, error code preservation, non-Error rejection normalization, and SSR activation bindings.
  • Bundle size from bundled TypeScript source: browser.ts 185,440 B raw / 34,884 B gzip -> browser.min.js 78,754 B raw / 23,362 B gzip (-106,686 B raw, -11,522 B gzip).

0.11.10 - 2026-06-18

  • Routed automatic microtask scheduler flush failures through an explicit error channel so failed jobs no longer surface as unhandled promise rejections.
  • Reported automatic flush failures to configured onError handlers or globalThis.reportError, with scheduler metadata for phase, scope, and key, while preserving manual scheduler.flush() rejection behavior.
  • Added regression coverage for automatic onError reporting, reportError delivery without unhandled rejections, and manual flush rejection metadata.
  • Bundle size from bundled TypeScript source: browser.ts 184,238 B raw / 34,642 B gzip -> browser.min.js 78,267 B raw / 23,232 B gzip (-105,971 B raw, -11,410 B gzip).

0.11.9 - 2026-06-18

  • Normalized scheduler batch thenables with Promise.resolve(value) before attaching cleanup, so PromiseLike values that implement .then() without .finally() are accepted.
  • Preserved batch-depth restoration, post-batch flushing, and manual rejection propagation for fulfilled, rejected, and native Promise batch work.
  • Added scheduler regression coverage for thenables without .finally(), rejected thenable batches, and Promise rejection propagation.
  • Bundle size from bundled TypeScript source: browser.ts 183,444 B raw / 34,419 B gzip -> browser.min.js 77,949 B raw / 23,138 B gzip (-105,495 B raw, -11,281 B gzip).

0.11.8 - 2026-06-18

  • Scoped server-result application tracking to each framework invocation so the same envelope object can apply effects again for separate calls without double-applying inside one nested server call chain.
  • Stopped mutating caller-owned server-result objects to record application state, including extensible, sealed, frozen, redirect, and error envelopes.
  • Added regression coverage for repeated shared-envelope invocations, frozen/sealed envelopes, original server errors, repeatable redirects, and unchanged result-object own keys.
  • Bundle size from bundled TypeScript source: browser.ts 183,427 B raw / 34,417 B gzip -> browser.min.js 77,932 B raw / 23,134 B gzip (-105,495 B raw, -11,283 B gzip).

0.11.7 - 2026-06-18

  • Introduced an explicit __async_server_result__: 1 marker for framework server-result envelopes so ordinary domain objects with fields such as value, signals, cache, html, boundary, redirect, or error remain application values.
  • Centralized server-result effect application and unwrapping across local registry, remote proxy, and handler command paths so .run(...) and namespaced calls return equivalent values without double-applying effects.
  • Kept cache-only and other effect-only server envelopes representable through the explicit marker and updated server-call, router, partial, and SSR examples to use the protocol.
  • Bundle size from bundled TypeScript source: browser.ts 183,176 B raw / 34,360 B gzip -> browser.min.js 77,854 B raw / 23,100 B gzip (-105,322 B raw, -11,260 B gzip).

0.11.6 - 2026-06-18

  • Owned async-signal runs with private execution tokens so canceled, restored, disposed, unregistered, or superseded work cannot commit late values, errors, or subscriber notifications.
  • Captured per-run this.abort and this.server context so older async work cannot observe or cancel a newer run's abort signal after an await.
  • Settled cancellation state immediately for non-cooperative loaders and canceled queued initial async scheduler work during disposal.
  • Bundle size from bundled TypeScript source: browser.ts 183,459 B raw / 34,391 B gzip -> browser.min.js 77,987 B raw / 23,148 B gzip (-105,472 B raw, -11,243 B gzip).

0.11.5 - 2026-06-18

  • Treated materialized signals and lazy async-signal descriptors as one logical namespace so duplicate IDs are rejected consistently.
  • Fixed lazy async-signal unregister(...) before and after materialization so removed descriptors cannot rematerialize.
  • Preserved reusable app async-signal declarations when materialized runtime async state is destroyed.
  • Bundle size from bundled TypeScript source: browser.ts 181,266 B raw / 33,853 B gzip -> browser.min.js 77,285 B raw / 22,868 B gzip (-103,981 B raw, -10,985 B gzip).

0.11.4 - 2026-06-18

  • Restored snapshot signal keys as exact IDs so dotted plain, async, and component-scoped signal IDs such as product.load survive SSR activation without becoming nested properties under their first segment.
  • Adopted async-signal descriptors before restoring matching snapshot state so dotted async signals preserve $value, $status, and $version without an immediate client refresh.
  • Kept server-result signal patches on nested first-segment path semantics for updates such as product.title.
  • Bundle size from bundled TypeScript source: browser.ts 180,585 B raw / 33,742 B gzip -> browser.min.js 76,946 B raw / 22,793 B gzip (-103,639 B raw, -10,949 B gzip).

0.11.3 - 2026-06-18

  • Isolated runtime-owned signal, async-signal, scheduler, request, and cache state so each createApp(...) call materializes fresh mutable state from reusable app declarations.
  • Preserved reusable app declarations across runtime destroy/recreate cycles, late app.use(...) adoption, server render repetition, and peer async-signal subscribers.
  • Added direct runtime-isolation regression coverage and regenerated the published browser/server artifacts.
  • Bundle size from bundled TypeScript source: browser.ts 179,469 B raw / 33,612 B gzip -> browser.min.js 76,458 B raw / 22,690 B gzip (-103,011 B raw, -10,922 B gzip).

0.11.2 - 2026-06-18

  • Published the post-0.11.1 feedback-regression hardening now on main, including scheduler scope revival, server error envelopes, async-signal SSR snapshot restore, lazy component error handling, router prefetch context, server proxy transport validation, and package export smoke coverage.
  • Refreshed the generated Async Pipeline workflow and lock metadata to @async/pipeline 0.9.1.
  • Ignored local docs/goals/ GoalBuddy planning bundles.

0.11.1 - 2026-06-17

  • Removed the literal old global fetch identifier from published release notes so package-wide text scans stay focused on runtime artifacts.
  • Hardened scheduler scope revival, server error envelopes, async-signal SSR snapshot restore, lazy component sync-rendering errors, router prefetch context, server proxy transport validation, and package export smoke tests.
  • Bundle size from bundled TypeScript source: browser.ts 177,243 B raw / 33,354 B gzip -> browser.min.js 75,517 B raw / 22,516 B gzip (-101,726 B raw, -10,838 B gzip).

0.11.0 - 2026-06-17

  • Removed the networked ssr-spa router mode and route-fragment fetching so ssr activates server-rendered HTML and snapshots without client route fetches.
  • Changed browser navigation to render registered SPA partials locally in spa and csr modes while leaving same-origin document navigation alone in ssr and mpa modes.
  • Replaced the server proxy's implicit global fetch default with an explicit transport callback supplied by application code.
  • Published only generated runtime artifacts and declarations: browser.*, server.js, framework.ts, and framework.d.ts; source, tests, and examples are no longer included in the package tarball.
  • Added regression coverage for SSR snapshot activation without fetch, SPA stale/error navigation behavior, explicit server proxy transports, and static generated-bundle scans for implicit global fetch access.
  • Bundle size from bundled TypeScript source: browser.ts 171,908 B raw / 32,421 B gzip -> browser.min.js 72,827 B raw / 21,845 B gzip (-99,081 B raw, -10,576 B gzip).

0.10.2 - 2026-06-17

  • Fixed intercepted router link, form, and popstate navigation failures so they update router error state and do not create unhandled promise rejections.
  • Preserved native same-document hash link behavior and made malformed encoded dynamic route params fall back to the raw segment instead of throwing.
  • Hardened rootless detach cleanup, lazy descriptor import retry, server JSON transport validation, and cache.getOrSet(...) handling for cached undefined values.
  • Expanded regression coverage for scheduler reentrancy, boundary receiver patch shapes, root lifecycle, lazy descriptors, server transport edge cases, component lifecycle ordering, and installed package export-map shape.
  • Bundle size from bundled TypeScript source: browser.ts 173,774 B raw / 32,727 B gzip -> browser.min.js 73,680 B raw / 22,047 B gzip (-100,094 B raw, -10,680 B gzip).

0.9.0 - 2026-06-17

  • Added createBoundaryReceiver(...) for optional out-of-order boundary patch delivery with per-boundary sequence checks, signal/cache effect ordering, scheduler flushing, redirects, and destroyed parent-scope filtering.

0.8.0 - 2026-06-17

  • Split browser and server entrypoints with @async/framework/browser, @async/framework/server, browser-only CDN bundles, and server-only local function registry exports.

  • Added the Layer 1.5 scheduler for deterministic signal binding, lifecycle, effect, async, and post-flush phases.
  • Added browser microtask scheduling by default and manual scheduler flushing for server render paths.
  • Threaded this.scheduler through loader, handler, component, async signal, server, router, and partial contexts.

0.7.0 - 2026-06-17

  • Added router navigation abort/version guards so stale route partials cannot clobber newer navigations, and route partial contexts receive this.abort.
  • Added ranked route matching so static and dynamic routes win over wildcard fallbacks regardless of registration order.
  • Added readSnapshot(...) and automatic browser activation from SSR snapshot scripts.

0.6.0 - 2026-06-17

  • Added Loader as the canonical public loader factory, including Async.Loader(...) for UMD script-tag usage, while keeping AsyncLoader as a compatibility alias.

  • Added package exports and docs for ESM, compact ESM, UMD, compact UMD, and TypeScript source/types entrypoints.
  • Added exported helpers to the UMD-only globalThis.Async object for script-tag CDN usage while keeping ESM Async as the app hub export.
  • Added UMD namespace conflict checks so generated helpers cannot silently overwrite app-hub fields such as use, start, or registry.
  • Added registry:lint, a cached package linter that emits a local registry manifest and detects conflicting signal, handler, server, partial, route, or component declarations while skipping generated root bundles.

0.5.0 - 2026-06-17

  • Added this.suspense(signalRef, views) for component-owned async boundary templates without adding a wrapper, rerender loop, hydration, or promise throwing.
  • Added signal:prop:* property bindings and tests for inline signal refs in signal:text, signal:attr:*, and signal:prop:*.
  • Added explicit unregister(id) APIs to runtime registries and component cleanup for scoped signals, async signals, computed signals, and handlers.

  • Added generated component-local signals via this.signal(initial).

0.3.0 - 2026-06-17

  • Added a shared registry store behind Async, app runtimes, and concrete registries so apps can inspect signals, handlers, server ids, routes, partials, components, and split cache state from one place.
  • Added configurable HTML attribute prefixes, with async:*, signal:*, and on:* as the defaults plus explicit support for data-async-*, data-signal-*, and data-on-*.
  • Declared the UNPKG package entry explicitly so the package root can be used as a no-build browser ESM CDN import.
  • Documented the UNPKG import-map setup for importing @async/framework by package name in no-build browser apps.

0.2.2 - 2026-06-17

0.2.1 - 2026-06-17

  • Fixed the generated release pipeline for the no-build package by verifying npm and GitHub Release parity without requiring a GitHub Packages mirror.

0.2.0 - 2026-06-17
