Pull request overview

This PR refactors @rsbuild/plugin-svgr to stop relying on prebundled/patch-managed url-loader + file-loader for mixed SVG imports, and instead uses a new internal SVG asset loader to preserve the same “inline under limit, otherwise emit file” behavior with fewer external build-time hacks.

Changes:

• Replace the url-loader-based mixed import handling with a new internal assetLoader (built as assetLoader.mjs).
• Remove prebundle setup and the file-loader / url-loader patched dependency workflow.
• Update snapshots and package metadata to reflect the new loader path and dependency set.

• generatorOptions?.filename can be an AssetModuleFilename function (not just a string) and may also be undefined; passing it as the name option will break assetLoader (it relies on loader-utils.interpolateName, which expects a template string or a (resourcePath, resourceQuery) callback). Please ensure the option passed here is always a string template (e.g. fall back to Rsbuild’s default svg filename) and handle the function case explicitly (e.g. by deriving a string template or using a different code path).

Code Review

This pull request replaces the external url-loader and file-loader dependencies with a custom internal assetLoader for SVG assets, removing legacy patches and the prebundling process. Feedback identifies a missing loader-utils dependency in package.json, a logic error in assetLoader.ts when handling function-based name templates, and the fragility of hardcoding the .mjs extension in the loader path.
