There are several libraries used in the project that help us to keep our codebase healthy:

Every time we commit something it will execute the linters and format the staged files if needed.

If you want to check them individually you could execute the following scripts:

npm run lint
npm run csslint
npm run format


We are using Jest as the testing platform.

npm run test
