Versions

[Unreleased]

Changes since the last non-beta release.

Added

• Added SHAKAPACKER_SKIP_PRECOMPILE_HOOK environment variable to skip precompile hook. [PR #850](shakacode/shakapacker#850) by justin808. Set SHAKAPACKER_SKIP_PRECOMPILE_HOOK=true to skip the precompile hook during compilation. This is useful when using process managers like Foreman or Overmind to run the hook once before starting multiple webpack processes, preventing duplicate hook execution. Migration tip: If you have a custom bin/dev script that starts multiple webpack processes, you can now run the precompile hook once in the script and set this environment variable to prevent each webpack process from running the hook again. See the precompile hook documentation for implementation examples.

[v9.3.4-beta.0] - November 17, 2025

Fixed

• Fixed switch_bundler task to remove packages from both dependencies and devDependencies. [PR #838](shakacode/shakapacker#838) by justin808. The task now correctly removes old bundler packages regardless of whether they're in dependencies or devDependencies sections, fixing an issue where packages in dependencies were not being removed when switching bundlers.

[v9.3.3] - November 15, 2025

Fixed

• Fixed switch_bundler task to preserve shared dependencies. [PR #836](shakacode/shakapacker#836) by justin808. The task no longer removes @swc/core, swc-loader, and webpack-merge when switching bundlers, as these packages are shared between webpack and rspack configurations.

[v9.3.2] - November 10, 2025

Fixed

• Fixed TypeScript import error in public types when webpack is not installed. [PR #828](shakacode/shakapacker#828) by G-Rath. Uses @ts-ignore instead of @ts-expect-error to suppress potential import error when webpack is not installed.
• Fixed bundler switch task to add missing assets_bundler config. [PR #833](shakacode/shakapacker#833) by justin808. The rake shakapacker:switch_bundler task now automatically adds the assets_bundler key to shakapacker.yml if it's missing, preventing silent failures when switching bundlers.
• Fixed rake tasks to use bundle exec rake instead of bundle exec rails. [PR #830](shakacode/shakapacker#830) by Judahmeek. Rake tasks should be invoked with bundle exec rake to support command-line flags properly, as Rails commands don't support flags.

Added

• Support for esbuild 0.26 and 0.27. [PR #832](shakacode/shakapacker#832) by justin808. Extended peer dependency range to support newer esbuild versions.

Changed

• Simplified switch_bundler task to only support rake command. [PR #831](shakacode/shakapacker#831) by justin808. The rake shakapacker:switch_bundler task now only works with bundle exec rake, not bundle exec rails. Use bundle exec rake shakapacker:switch_bundler [bundler] -- [options] for clearer command-line flag support.

[v9.3.1] - November 9, 2025

Fixed

• Fixed NODE_ENV not being set when running shakapacker-dev-server. [PR #823](shakacode/shakapacker#823) by Seifeldin7. Resolves #802. The dev server now properly initializes NODE_ENV to match RAILS_ENV (or "production" by default), fixing webpack configurations that dynamically load environment-specific files.
