Update peer dependency range to target Vite 5

There were no breaking change that impacted this plugin, so any combination of React plugins and Vite core version will work.

Align jsx runtime for optimized dependencies

This will only affect people using internal libraries that contains untranspiled JSX. This change aligns the optimizer with the source code and avoid issues when the published source don't have React in the scope.

Reminder: While being partially supported in Vite, publishing TS & JSX outside of internal libraries is highly discouraged.

Add @vitejs/plugin-react-swc/preamble virtual module for SSR HMR (#890)

SSR applications can now initialize HMR runtime by importing @vitejs/plugin-react-swc/preamble at the top of their client entry instead of manually calling transformIndexHtml. This simplifies SSR setup for applications that don't use the transformIndexHtml API.

Use SWC when useAtYourOwnRisk_mutateSwcOptions is provided (#951)

Previously, this plugin did not use SWC if plugins were not provided even if useAtYourOwnRisk_mutateSwcOptions was provided. This is now fixed.

• Enable retainLines to get correct line numbers for jsxDev (fix #235)

• Add @types/babel__cores to dependencies (fix #211)
• Improve build perf when not using Babel plugins by lazy loading @babel/core #212
• Better invalidation message when an export is added & fix HMR for export of nullish values #215
• Include non-dev jsx runtime in optimizeDeps & support HMR for JS files using the non dev runtime #224
• The build output now contains a index.d.cts file so you don't get types errors when setting moduleResolution to node16 or nodenext in your tsconfig (we recommend using bundler which is more close to how Vite works)

Set SWC cacheRoot options

This is set to {viteCacheDir}/swc and override the default of .swc.

Perf: simplify refresh wrapper generation (#835)

• Fix #198: Enable Babel if presets list is not empty

[email protected]

• Revert #108: Remove throw when refresh runtime is loaded twice to enable usage in micro frontend apps. This was added to help fix setup usage, and this is not worth an annoying warning for others or a config parameter.

• Fix fast-refresh for files that are transformed into jsx (#188)

• Support Vitest deps.experimentalOptimizer
• Support using components inside web workers (#181)
