AWS Amplify CLI
The AWS Amplify CLI is a toolchain which includes a robust feature set for simplifying mobile and web application development. The CLI uses AWS CloudFormation and nested stacks, which allows you to add or modify configurations locally before you push them for execution in your account.
If you're using Windows, the CLI currently supports Windows Subsystem for Linux.
Install the CLI
- Requires Node.js® version 8.11.x or later
Install and configure the Amplify CLI as follows:

|amplify init||Initializes a new project, sets up deployment resources in the cloud and prepares your project for Amplify.|
|amplify configure project||Updates configuration settings used to setup the project during the init step|
||Adds cloud features to your app.|
||Updates existing cloud features in your app.|
|amplify push [--no-gql-override]||Provisions cloud resources with the latest local developments. The 'no-gql-override' flag does not automatically compile your annotated GraphQL schema and will override your local AppSync resolvers and templates.|
|amplify status||Displays the state of local resources that haven't been pushed to the cloud (Create/Update/Delete).|

To test your category, do the following:
cd <your test front-end project>
amplify <your category> <subcommand>
Before pushing code or sending a pull request, do the following:
- At the command line, run
npm run lintat the top-level directory. This invokes lerna to check for lint errors in all of our packages.
- You can use
eslintto fix some of the lint errors. To use it, go to the package that has errors and run
- 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.
