Configuring Prettier for the first time and I understand that things like build/deploy files and node_modules (obviously) should be ignored, as well as auto-generated files like package-lock.json. What about package.json? It's partially auto generated but people also go in and edit it manually, so I think there is value in running Prettier on it. Any other best practices for what to include/not include in the ignore file? I'm assuming submodules should be left in once Prettier has been run on the submodule.
I would recommended to allow prettier and other linters to read/lint package.json.
You want to keep things tidy and consistent. Rule of thumb is if it's not autogenerated then go ahead.
