This repository contains codemods (automated migrations) for webpack. These codemods facilitate adopting new features and upgrading to versions with breaking changes.

Quickstart

# Run a specific codemod from the registry
npx codemod@latest webpack/v5/json-imports-to-default-imports

# Run the combined migration recipe
npx codemod@latest webpack/v5/migration-recipe

# Run locally from a recipe directory
codemod run -w workflow.yaml

See the codemod CLI doc for a full list of available commands.

Caution

These scripts change source code. Remember to commit any wanted and unsaved changes before running them.

To run codemods, use codemod command below:

npx codemod @webpack/<recipe>

• webpack/v5/json-imports-to-default-imports — replace JSON named imports with default import
• webpack/v5/migrate-library-target-to-library-object — migrate output.library and output.libraryTarget to v5 format
• webpack/v5/set-target-to-false-and-update-plugins — move functional target into plugins and set target: false
• webpack/v5/migration-recipe — orchestrates the above in sequence
