This course teaches you everything you need to know about GraphQL. GraphQL was open sourced by Facebook in 2015 and is a fresh new approach to API development.

GraphQL will replace REST in the coming years. Don't just take my word for it though, here's what some other folks on Twitter are saying:

"Just watched a talk on GraphQL, I want this thing and I want it by yesterday" – @sunesimonsen

"I long for the day when GraphQL will be the new API standard."@xinron

"GraphQL is the King. Long Live the King! (R.I.P. REST)" – @scbarrus


About this course:

  • We build two projects from scratch so you have everything you need to know to use GraphQL
  • Full, free lifetime access
  • Unconditional Udemy 30 day money-back guarantee - that's my personal promise of your success!
  • On-screen, over my shoulder view of where to go, what to click on, and how to set everything up from start to finish

What you'll learn:

  • How the GraphQL schema works so you can use GraphQL on your own servers
  • How to query GraphQL so you can access and mutate your data
  • We'll start simple, creating a schema with dummy data
  • Then we'll hook up our with schema to a live Star Wars API
  • We'll learn how to query the data, filter the data, and optimize the queries with DataLoader
  • We'll cover how to put the schema on an Express server so you can get access to your data with just HTTP requests
  • Then we'll get started with mutations, the GraphQL version of POST, PUT, and DELETE of REST
  • We'll build a blog API using just GraphQL mutations and queries, tying everything we've learned so far
  • We'll cover the state of GraphQL Subscriptions, an emerging and evolving standard

So you've read this far! Thank you.

One final and important point

If you've ever had trouble working with REST in the past, it's not your fault. It's been the recommended way of building APIs since 1996. There are countless articles on creating "thoughtful RESTful APIs", but none of them ever seem to apply to what you're working on. GraphQL offers a way out of this madness.

I've been running a GraphQL server in production for the last 3 months and it's sped up our response time, simplified our architecture and made it easier to access our data. I am not alone. Many multi-million dollar companies are also seeing the benefits of GraphQL in production including the Financial Times, Artsy, and Facebook.

Let's get started. Click the "Take this Course" button in the top-right corner right now and I'll see you on the other side.

GraphQL Basics
3 Lectures 17:13

In this lecture we cover the basics of GraphQL and talk about the benefits of using GraphQL over REST.

Preview 07:38

This lecture covers the GraphQL schema syntax in depth

Preview 04:21

This lecture covers the GraphQL query language and how these queries relate and are executed against the schema.

Understanding GraphQL Queries
GraphQL Queries
8 Lectures 01:31:51

In this lesson we build our first GraphQL schema using graph.ql.

Creating our First GraphQL Schema

In this lesson we implement our first schema. We talk about how to implement scalars, fill in type implementations and kick off the GraphQL query.

I've attached the final code if you'd like to follow along with the code in front of you.

Implementing our GraphQL Schema

In this lesson we learn about how to add filters to our queries to support rich querying.

Adding Filters to our GraphQL Schema

In this lecture we connect our schema to a live API. You will truly understand the power of GraphQL after watching this lecture.

Getting Real: Hooking our GraphQL Schema up to a Starwars API

Up until this point, we were executing queries directly in our editor. In this lesson, we create a server to serve our GraphQL schema. After this lesson you'll be able to query your data by making requests to the server.

GraphQL on the Server

In this lecture, we learn about GraphiQL, which is an editor that makes testing, debugging and administrating GraphQL servers much, much easier. This lecture will make you fall in love with GraphQL a second time.

Getting to Know GraphiQL

Up until this point, we were naively making HTTP requests to the Star Wars API. In this episode we look at optimizing and actually simplifying these queries using Facebook's DataLoader.

This is the 1st part of a 2 part lecture.

Optimizing our Queries with DataLoader (Part I)

This is the 2nd part of using the DataLoader. After you finish this lecture, you'll have a production-ready GraphQL server.

Optimizing our Queries with DataLoader (Part II)
GraphQL Mutations
4 Lectures 28:34

In this lecture, we learn about GraphQL mutations and how they work.

Introduction to GraphQL Mutations

In this lecture, I show you what we're going to have created by the end of this section.

What We're Going to Build

In this lecture, we're going to implement our Blog schema from scratch.

Creating our Blog Schema

In this lecture, we're going to take our built GraphQL schema and serve and manipulate it using Express and GraphiQL.

Serving our Blog Schema
GraphQL Subscriptions
1 Lecture 05:28

In this lecture, I cover the basics of GraphQL subscriptions. This lecture does not come with an implementation because the semantics of subscriptions have not been ironed out yet (it was just introduced a month ago).

I'm going to give you the lay of the land in this lecture, and will be adding more videos (for free) as the spec gets ironed out.

Web Developer. Open Source Advocate. Light Packer.

I've been building websites for the last 12 years. In college I spent 3 years teaching college students how to design and build websites. After college I packed up my bags and moved to San Francisco to work for various companies large and small including Yahoo, Automattic and Coinbase. In addition to working for other companies, I've also helped start some web companies including Lapwing Labs, Gittask and Finbox. I put most of my code up on Github for anyone to learn from and use for free.

Over the years, I've consistently tried to simplify complex development concepts into digestable, easy to understand principles.

I'm here to teach you these principles and discoveries, so you are empowered to create the next big thing in tech.

Feel free to reach out with your questions and comments. I look forward to hearing from you!
