Project uses npm but Rails standard is yarn

[arielj]

Branch/Commit:

Main branch

Expected behavior:

New Rails applications use yarn to handle node modules, we should use the same here for consistency.

Actual behavior:

The app uses npm to handle node modules. On CI it is running both npm install manually and then rails runs yarn install when compiling the assets.

Notes:

We should document how to install node modules using yarn and add a yarn.lock file to the repo instead of the package-lock.json file that is created by npm.

I will abide by the code of conduct

I don't think this is a bug
