A command-line tool for converting projects that use yarn to npm.

The follow-up to npm2yarn. See https://mixmax.com/blog/to-yarn-and-back-again-npm for motivation.

deyarn:

1. Removes yarn.lock if it exists
2. Removes node_modules to avoid any installation conflicts
3. Installs your project dependencies using npm, generating a package-lock.json file
4. Logs a list of manual steps to be taken to complete the transition

This conversion will likely involve the upgrading of some/many of your transitive dependencies, so make sure to test thoroughly! :)

You can use deyarn via npx to quickly convert a project without needing to install deyarn first. Just run the following command in your project directory:

npx deyarn

Note: The directory must be a Git repository.

Alternatively you can install deyarn globally (see below) and then run $ deyarn in your project directory instead.

npm install -g deyarn

or

yarn global add deyarn
