You can now develop all of your AppSync API's locally using Serverless + Serverless-AppSync-Plugin! With support for AWS DynamoDB, AWS Lambda, and AWS Elastic Search; you have everything you need to get started developing your AppSync API's locally.

Find AppSync examples in the Serverless-GraphQL Repo 👈

▶️ Usage

serverless deploy

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

📝 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.

👷 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. 🍹
