lodash-codemods

Codemods for Lodash that simplifies upgrading to newer versions

Codemods are small programs that help you automate changes to your codebase. Think of them as search and replace on steroids.

This module contains a set of codemods that enable you to upgrade your code between various Lodash releases.

WARNING

This tool should help migrate your codebase from one version of Lodash to another. That said, it may not be 100% complete or able to apply all the necessary changes. You should NOT rely on the fact that this will work entirely, and you therefore NEED to review the changes made and test that your code is still working.

In cases where static analysis is not enough to figure whether a change should be made, instructions will be printed to the console, and you should follow them to complete the migration.
