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@latest <codemod-name>

For example:

npx codemod@latest @mswjs/v3

From source

npx codemod workflow run -w /path/to/folder/containing/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.
