patch-package

When forking just won't work, patch it.

patch-package lets you easily fix bugs in (or add functionality to) packages in your node_modules folder and share the results with your team. You simply make the changes in situ, run patch-package <package-name> and patch-package will create a patch file for you to commit, which gets applied any time the contents of node_modules is updated by yarn/npm.

Set-up

yarn add -D patch-package

In package.json

"scripts": {
  "prepare": "patch-package"
}

Usage

Make changes to the files of a particular module in your node_modules folder, e.g. react-native. Then run:

patch-package react-native

If this is the first time you've used patch-package, it will create a folder called patches in the root dir of your app. Inside will be a file called react-native:0.44.0.patch which is a diff between normal old react-native and your special version. Commit this and you and your team will enjoy the same changes from here on out.

Do exactly the same thing to update the patch file, or just delete it if you don't need the changes anymore.
