Video: Deploying a Serverless GraphQL API - Sashko Stubailo

What's inside:

Sashko Stubailo from Apollo speaks about deploying a serverless GraphQL API with AWS Lambda and Apollo Engine. More and more, we find that GraphQL APIs are being developed by product developers that don't want to worry about operating backend services. The serverless function model of deployment has a lot of benefits for APIs, but isn't as well suited when you need some stateful features such as caching or performance metrics aggregation. In this talk, Sashko presents a solution that combines the best of both worlds: A stateless GraphQL API running in AWS Lambda for ease of deployment with Apollo Engine in front to handle stateful concerns.

In this client-sided GraphQL application we’ll build together, you will learn how to combine React with GraphQL. There is no clever library like Apollo Client or Relay to help you get started yet, so instead, you will perform GraphQL queries and mutations with basic HTTP requests. Later, in the next application we are going to build together, I’ll introduce Apollo as a GraphQL client for your React.js application

A complete React with Apollo and GraphQL Tutorial by Robin Wieruch

What’s inside:

In this tutorial, you will learn how to combine React with GraphQL in your application using Apollo. The Apollo toolset can be used to create a GraphQL client, GraphQL server, and other complementary applications, but you will use the Apollo Client for your React client-side application. Along the way, you will build a simplified GitHub client that consumes GitHub’s GraphQL API using Apollo instead of plain HTTP requests like the previous application.

ELIXIR

Graphql-elixir introduction @HowToGraphQL by Ben Wilson

What’s inside:

Server
- Elixir: The programming language https://elixir-lang.org/
- Phoenix: Web framework in Elixir https://www.phoenixframework.org/
- Absinthe: GraphQL implementation for Elixir that will handle running GraphQL queries submitted via Phoenix. http://absinthe-graphql.org/
Testing
- GraphiQL: Extremely useful tool for quickly testing GraphQL apis. By the end of this tutorial you should be able to update your previous frontend code to replace the Graphcool endpoint and point to your new server instead, but until then it’ll be easier for us to test the api through GraphiQL. Among other things, it:
  - Generates a comprehensive documentation of all your available queries and mutations.
  - Provides a text editor where you can build requests, with syntax highlighting and autocomplete.
  - Displays the server’s responses.
