Course Introduction

GraphQL is becoming the new way to use APIs in modern web and mobile apps.

However, learning new things always takes time and without getting your hands dirty, it’s very hard to understand the nuances of a new technology.

So, we put together a powerful and concise course that will introduce you to GraphQL and integrating GraphQL into your frontend stack, in the shortest amount of time possible.

We will explore the fundamentals of GraphQL and the things that make GraphQL especially suitable for modern applications, like its realtime capabilities! The course is light on opinions so that once you grok the fundamentals you can go on to choose your favorite libraries, tools and tailor your workflow.

Key topics and takeaways:

GraphQL vs REST
GraphQL queries, mutations, subscriptions
Setting up a GraphQL client with Apollo
Integrating GraphQL queries in your react native app
Integrating GraphQL mutations in your app to change data on the server
Updating local state after a GraphQL mutation (TextInput) using Apollo cache
Automatic updates to local state and UI after mutations
Using GraphQL subscriptions
Building a real-time feed with notifications using mutations and subscriptions

What will we be building?

We will be building a realtime todo app using authenticated GraphQL APIs.

Will this course teach React Native as well?

No, we will be simulating a scenario where we already have a GraphQL API and the basic UI of a React Native app built. Our task in this scenario is to integrate the GraphQL APIs into our react native app to build a complete and working app.

If you're new to React Native, we recommend going through this tutorial and then coming back here!
