Introduction

If you want to get new-agey and deploy a GraphQL API in a serverless architecture, what’s the best way? You can make that work with API Gateway but it’s a little cludgey and normally results in implementing a super Lambda function that contains all your GraphQL resolver logic.

Lucky us! AWS has a GraphQL specific API proxy called AppSync. Last month, I did an article overviewing AppSync and concluded I would try it out on an upcoming project. Well dear reader, I have done it and now I am bringing you my results!

Introduction

I recently learned about AWS AppSync while perusing A Cloud Guru courses and stumbling on this one: “Introduction to AWS AppSync”. I am excited! AppSync is a managed service for deploying GraphQL APIs. Think of it like API Gateway but for GraphQL instead of HTTP requests.

GraphQL is to AppSync as HTTP is to API Gateway.

From the course learnin and my trials so far, the workflow breaksdown like this:

Upload a GraphQL schema document
Configure data sources
Map schema to data sources with resolvers

Let’s do a quick dive into each. I am gonna cheat and not go into a couple topics: authentication and querying. I’ll save those for other posts. But I am happy that AppSync supports AWS Cognito out-of-the-box.
