    Be sure to replace all variables that have been commented out, or have an empty value.

    ▶️ Usage

    serverless deploy

    This command will deploy all AppSync resources in the same CloudFormation template used by the other serverless resources.

    serverless graphql-playground

    This command will start a local graphql-playground server which is connected to your AppSync endpoint. The required options for the command are different depending on your AppSync authenticationType.

    For API_KEY, either the GraphQLApiKeyDefault output or the --apiKey option is required

    For AMAZON_COGNITO_USER_POOLS, the -u/--username and -p/--password arguments are required. The cognito user pool client id can be provided with the --clientId option or directly in the yaml file (custom.appSync.userPoolConfig.playgroundClientId)

    For OPENID_CONNECT, the --jwtToken option is required.

    The AWS_IAM authenticationType is not currently supported.

    📝 Notes

    • If you are planning on using AWS Elastic Search, you will need to create an Elastic Search domain/endpoint on AWS and set it as the endpoint option in serverless.yml before deploying.

    Offline support

    You can use serverless-appsync-offline to autostart an AppSync Emulator which depends on Serverless-AppSync-Plugin with DynamoDB and Lambda resolver support:

    Install Plugin

    npm install --save serverless-appsync-offline

    Minimal Options (serverless.yml)

    custom:
      appsync-offline:
        port: 62222
        dynamodb:
          server:
            port: 8000

    Start local enviroment

    If you use serverless-offline:

    sls offline start

    otherwise:

    sls appsync-offline start

    the result is:

    Serverless: dynamoDB started: http://localhost:8000/
    Serverless: AppSync started: http://localhost:62222/graphql
    

    Go to serverless-appsync-offline to get further configuration options.

    👷 Migration from versions prior to 1.0

    If you have previously used versions of this plugin prior to 1.0, you will need to perform some additional manual steps in order to continue use of this plugin (it will be worth it). This change removes the sls *-appsync commands in favor of adding AppSync resources directly to the serverless cloudformation stack. What this means for your existing APIs is that they can no longer be updated. The good news is that you will no longer need to use separate commands to deploy vs update and update your serverless config with the created apiId.

    The rough steps for migration are as follows:

    1. Run sls deploy to create the new AppSync api and make note of the endpoint returned as part of the stack outputs. If you were using an API_KEY auth type, you will also need the new api key which is also included in the stack outputs.
    2. Update existing consumers of your API to use the new endpoint. If you're using an api key, this will also need updated
    3. After verifying all existing consumers are updated, run sls delete-appsync to cleanup the old resources
    4. Remove the apiId line from custom.appSync in serverless.yml
    5. 🍹
