vite-plugin-image-optimizer 1.1.7 sharp svgo peerDependencies dynamic import README
💡 Result:
In version 1.1.7 of vite-plugin-image-optimizer, released on August 12, 2023, the plugin introduced a significant architectural change regarding its dependencies, sharp and svgo [1][2][3]. Key details include: Dynamic Imports: To support both CommonJS and ES module environments (such as vite.config.mjs), version 1.1.7 implemented dynamic imports for sharp and svgo [2][4]. This allows these heavy dependencies to be loaded on-demand rather than synchronously at startup [2]. Peer Dependencies: Because sharp and svgo are handled via dynamic imports, they are marked as optional peer dependencies [5][2]. This design decision enables users to install only the libraries they need—for example, skipping sharp if they only require SVGO, or vice versa [6]. Documentation and Requirements: The README emphasizes that sharp and svgo are not bundled with the plugin [6][7]. Users must install them manually as dev dependencies in their own projects [6][7]. For version 1.1.7, while explicit peer dependency ranges were defined in the package metadata, the core requirement is that these packages must be present in the user's environment for the corresponding features to function [2][6]. By treating these libraries as optional peer dependencies, the plugin avoids forcing unnecessary heavy dependencies on users who may not need the full suite of optimization features [6].

vite-plugin-image-optimizer v1.1.7 source generateBundle bundler[filePath].source Rollup asset hash timing
💡 Result:
In the context of vite-plugin-image-optimizer and similar Rollup-based plugins, the generateBundle hook operates on a bundle where asset file names and their associated hashes have typically already been resolved [1][2]. When the plugin attempts to modify an asset's content by updating bundler[filePath].source during this stage, it changes the actual file content without triggering a re-computation of the file's hash [1]. Because the file name (which often includes a [hash] placeholder) has already been determined by Rollup based on the original (pre-optimized) content, the final emitted file name will not reflect the changes made to the source content [1]. Key Technical Details: - Rollup's generateBundle Hook: By the time this hook is called, Rollup has already finalized the output manifest and resolved file names for all assets in the bundle [2]. - Asset Hashing Timing: Vite and Rollup resolve the [hash] placeholder based on the original asset content before it reaches the generateBundle hook [1]. Consequently, modifying the .source property at this late stage is effectively a "post-processing" step that updates the file content on disk but does not update the file name [1]. - Limitations: This behavior creates a disconnect where the optimized image content does not match the content-addressed hash in its filename [1]. This is a known limitation of using plugins that hook into generateBundle for asset optimization rather than performing transformations during earlier stages of the pipeline where Rollup's hashing logic still has the opportunity to react to content changes [1]. If you are encountering errors or unexpected behavior when modifying bundler[filePath].source, ensure you are correctly accessing the asset object. In some versions of vite-plugin-image-optimizer, improper access or attempts to modify non-asset bundle entries can lead to errors such as "Cannot set properties of undefined (setting 'source')" [3]. Official guidance often suggests that truly deterministic, hash-aware optimization requires specialized build-tool integration (like the proposed transformAsset hook in Rollup) that separates the emitting process from the transformation [1].

Recompute asset hashes after image optimization.
vite-plugin-image-optimizer v1.1.7 mutates emitted asset source values in generateBundle, after Rollup generates the [hash] filename from the original source. The filename can therefore identify pre-optimized bytes. This affects emitted assets; Vite-inlined images bypass this hook.
Use an optimizer that runs before asset naming, or add a post-build hash and reference-rewrite step. Test that changing only optimizer quality changes both the optimized bytes and the asset URL hash.

Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.
In `@vite.config.js` at line 25, Update the asset build configuration around
assetFileNames so hashing occurs after image optimization, replacing or
reconfiguring vite-plugin-image-optimizer as needed. Ensure emitted asset
filenames and all references use hashes derived from optimized bytes, while
preserving Vite-inlined image behavior; add coverage that changing optimizer
quality changes both optimized output and its asset URL hash.
