Developing

To set up your local development environment, go to Local Environment Setup.

To test your category, do the following:

cd <your-test-front-end-project>
amplify-dev init
amplify-dev <your-category> <subcommand>

Before pushing code or sending a pull request, do the following:

• At the command line, run yarn lint at the top-level directory. This invokes eslint to check for lint errors in all of our packages.
• You can use yarn lint to find some of the lint errors. To attempt fix them, go to the package that has errors and run yarn lint-fix
• If there are any remaining lint errors, resolve them manually. Linting your code is a best practice that ensures good code quality so it's important that you don't skip this step.
