Setting up

Plugin development is not yet fully self-contained, meaning you need the app skeleton, where you will add the plugin you want to develop as a dependency that is symlinked from a local folder.
However, this is needed only if you want to manually test the plugin in the app (in your browser), since running the tests uses a default Testbench Laravel skeleton.

Please note

The core package is in fact not a Filament plugin, but nevertheless, everything for plugin development also applies for core development.

1. Follow the above Getting started section to set up an app skeleton.
2. Then, git clone the plugin you want to work on to a local folder inside the app, e.g. packages/my-package.
3. Add the local folder as a repository in the app's composer.json, e.g.:

   "repositories": [
       {
           "type": "path",
           "url": "./packages/my-package"
       }
   ]

4. Run composer update to create the symlink.
