Official ESLint codemods to help users adopt new features and handle breaking changes with ease.

Community contributions are welcome and appreciated! Check open issues for codemods to build, or open a new one if something’s missing. See the contribution guide for details.

Running codemods

Caution

Codemods modify code! Run them only on Git-tracked files, and commit or stash changes first.

From the registry

Recommended for the best UX. This downloads the package from the Registry.

npx codemod <codemod-name>

For example:

npx codemod @eslint/v8-to-v9-config

From source

npx codemod workflow run -w ./codemods/v9/config-file/workflow.yaml

Note

By default, codemods run in the current folder. Add -t /target/path to change it.

See the Codemod docs for all CLI commands and options.
