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 to allow you to add or modify configurations locally before you push them for execution in your account.
Install the CLI
- Requires Node.js® version 10 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
The Amplify CLI supports the commands shown in the following table.
|amplify configure||Configures the AWS access credentials, AWS Region and sets up a new AWS User Profile|
|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 pull||Fetch upstream backend environment definition changes from the cloud and updates the local environment to match that definition.|
|amplify status||Displays the state of local resources that haven't been pushed to the cloud (Create/Update/Delete).|
|amplify delete||Deletes resources tied to the project.|
|amplify help | amplify
||Displays help for the core CLI.|
|amplify codegen add | generate||Performs generation of strongly typed objects using a GraphQL schema.|
|amplify env add | list | remove | get | pull | import | checkout||See the multienv docs.|

Before pushing code or sending a pull request, do the following:
- At the command line, run
yarn lintat the top-level directory. This invokes eslint to check for lint errors in all of our packages.
- You can use
yarn lintto find some of the lint errors. To attempt fix them, 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.
