This presentation was recorded prior to re:Invent. Learn how to migrate or upgrade your existing REST APIs to GraphQL with AWS AppSync and AWS Amplify. In this session, we go over the different strategies that you can use with AWS AppSync to leverage GraphQL, and we explain how to think in terms of a data API if you are used to developing REST APIs. We also cover the process of implementing AWS Lambda sources with AWS Amplify and using local mocking features to speed up development.
