Documentation
If you can, edit the docs that are there already & send a PR or add a new docs page with your info in it, but if you're not sure where to put it or even if it's relevant to anyone else, simply jot some thoughts/bullet points down in the docs/wip directory and send a PR. I'll find a place for it!
Previewing docs
# in the FAB project root
cd docs
yarn
yarn dev
E2E Tests
If you're looking to add any code/fix bugs in the core plugins, the most important thing is to extend the E2E tests to cover them. There's quite a few unit tests there, and they have definitely helped, but given the nature of the FAB project, it makes more sense to do exactly what a user would do:
- Take a project
- Configure it for FABs
- Serve the FAB and expect some result
How to run them
In one terminal:
# in the FAB project root
yarn
yarn build
yarn link-all
yarn build:watch
In a second terminal:
# from the FAB project root
cd tests
yarn
yarn test
This will run a create-react-app and a nextjs test suite, where it creates a new project (using CRA or create-next-app), then runs fab init, then runs fab build, then runs fab serve fab.zip. It should pass on your machine, if doesn't raise an issue!
This test takes a long time, so to rerun the tests use the following command:
Rerunning tests
For create-react-app:
# in the fab/tests dir
FAB_E2E_SKIP_CREATE=true yarn test create-react-app
For nextjs:
# in the fab/tests dir
FAB_E2E_SKIP_CREATE=true yarn test nextjs
Tweaking tests & source code
Personally, I like to spin up a third console window and cd into the [cra|nextjs]-test dir and run fab build & fab serve fab.zip manually, then tweak the source code or config and rerun.
Because you ran yarn link-all back in the first terminal window, and because yarn build:watch is running in the background, changes you make to any of the FAB plugins should be instantly available. If they're not, check the output of yarn build:watch, there's probably typescript errors.
Once you have recreated the bug/situation you're interested in, update the tests to automatically change the blank project to your desired state as a separate step after all the others (see the existing tests there, that's how things work already). Then rerun your FAB_E2E_... yarn test ... and it should reset your test project and then configure it back to the state you're interested in.
Now you've got your setup, you can add expectations of what should happen to the tests, plus any FAB core code to fix them! Once it passes, fire up a PR and make sure it passes on Github CI as well, then you're done!
