This repo manages the API category within Amplify CLI. The Category is responsible for managing graphql build and transformation processes, generating resources to deploy into your cloud stack in order to compute and store data for your graphql and REST endpoints, and providing inputs to codegen processes for use later in your end application.

Install the CLI

• Requires Node.js® version 12 or later

Install and configure the Amplify CLI as follows:

$ npm install -g @aws-amplify/cli
$ amplify configure

Note: If you're having permission issues on your system installing the CLI, please try the following command:

$ sudo npm install -g @aws-amplify/cli --unsafe-perm=true
$ amplify configure

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.
