Introduction

I have been building GraphQL APIs in a Serverless environment for over 3 years now. I can’t even imagine working with RESTful APIs anymore. Combine the power of GraphQL with the scalability of AWS Lambda, and you have a server that can handle infinite amounts of traffic.

In this tutorial, we will build and deploy a GraphQL server to AWS Lambda and access it via an API Gateway endpoint. We will use CloudFormation and the AWS CLI to deploy all our AWS Resources and application code.

What we’ll cover

  1. Build a GraphQL Server using Apollo
  2. Deploy that GraphQL Server to Lambda
  3. Use API Gateway to proxy requests to Lambda
  4. Use CloudFormation to deploy application stack to AWS
  5. Set up Lambda for local development.

TL;DR – You can get the full source code for the application from Github.

What is GraphQL?

GraphQL is a query language for describing APIs using a strongly typed schema system. A GraphQL server fulfills those queries using existing data. Following are a few of the main advantages of using GraphQL.

Query only what your application needs

Unlike REST APIs, GraphQL enables clients to query precisely and only what they need. The server fulfills the client’s request by returning only what the client is asking for.

GraphQL uses a strongly typed system

The strongly typed system of GraphQL enables users to introspect the entire schema. And the GraphQL API serves as clear documentation about the capabilities of the server and notifies you about errors during development.

You can compose your queries in a single request

With GraphQL, you can query multiple resources and get combined responses with a single request. With fewer requests, apps using GraphQL perform much faster.

What is AWS Lambda?

AWS Lambda is a compute service offered by AWS that lets you run your application code without having to manage any servers. AWS manages all the overhead like infrastructure, security, resources, operating system, and patches so developers can focus on just building the application.
