Course Introduction

This course is a super-fast introduction to setting up a GraphQL backend with Hasura.

In 30 mins, you will set up a Powerful, Scalable Realtime GraphQL Backend complete with Queries, Mutations, and Subscriptions. You will also learn how Hasura helps you integrate custom business logic (in any programming language), both as custom GraphQL APIs that you write yourself, and as Event Triggers that run asynchronously and are triggered by database events.

What will I learn?

This course will help you understand the different Hasura features, when and how to use them, and is an ideal starting point before diving into advanced topics.

Hasura Basics: Use Hasura to generate the realtime GraphQL API powered by a Postgres database
Postgres power: Use the power of Postgres to make efficient data transformations so that we don't have to do them in code
Authorization: Setup authorization so that app users can only run operations on data that they should be allowed to
Authentication: Integrate a JWT based auth provider (using Auth0) with Hasura
Remote schemas: Add a custom GraphQL resolver to create an API for fetching data that is not in the database
Event triggers: Run business logic on the backend when there are database events

What will we be building?

We will be building the backend of a realtime todo app. If you're interested in building the Frontend and are new to GraphQL, head to the GraphQL tutorials for different frontend frameworks.

Try this deployed version of the app, to see what features our backend will need to have: https://learn-hasura-todo-app.netlify.com/

What do I need to take this tutorial?

Just your browser!

However, be assured that everything you do via the browser in this tutorial can be done via code, can be version controlled and can work with any programming language you choose on the server-side.

We've kept this course light on developer workflows and environment choices so that you can focus on the key concepts and go on to set up your favorite tools and workflows.
