If you want to make changes to code inside a dependency, patch-package provides a convenient solution to do that. It allows you to make changes directly to your node_modules directory, then generate a patch file that you can commit to source control and will be automatically re-applied to the package in node_modules when you run npm install (or yarn, etc.).
Out of the box, patch-package is fully compatible with EAS. If you follow the installation instructions for patch-package, including adding the postinstall script to your package.json, then any patches you have created in your project using patch-package will automatically be applied on EAS as part of the 'Install dependencies' step, just like on your local machine.
Note: make sure that the patches folder that is created by
patch-packageis added to source control, so it will be included when your source code is uploaded to EAS.
The output from patch-package is available in the logs for the 'Install dependencies' step on your build details page.
