Dry-run codemods

Before applying a codemod to your project, you can test it out in the dry-run mode and decide which parts of your codebase it should modify. This simplifies dependency upgrade tasks and allows you to easily review large codebase changes.

To dry-run a codemod:

  1. Find the codemod you would like to use.
  2. Click Dry Run.

Reviewing and applying changes

When you dry-run a codemod, all the changes are temporarily in preview before being applied to your local files. This allows you to accept or discard specific changes before applying them to the project’s files.

To review the changes made:

1. Select a dry run

2. Review and accept/decline file changes

Sometimes codemods may make unwanted changes to some files. In such cases, you can deselect changes to prevent them from being applied to your project.

You can use the diff view editor to manually edit the changed file before applying the changes.

3. Apply changes
