A Real-World GraphQL Tutorial Series by Hasura

Move from GraphQL basics to production ready concepts with our hands-on opensource tutorials for fullstack developers.

GraphQL APIs for Beginners

GraphQL is a query language for APIs. A GraphQL server following the GraphQL spec can be implemented using any programming language and can be consumed by any frontend.

An Introduction to GraphQL : GraphQL APIs for Beginners

GraphQL is open source and is maintained by the Linux Foundation. GraphQL API has a schema and type system. Learn more about the fundamentals of GraphQL through the resources listed below.

query {
  brands(order_by: ["id"], limit: 5) {
   id
   name
   products {
     id
     name
     image
   }
  }
}

GraphQL Mutations >

GraphQL mutation is a type of request that may result in the state of your backend "mutating" or changing, resulting in data being modified in the data store.

This mutation inserts a `product`. Mutations can be used for any type of write operation, including insert, update, and delete.

Learn more about GraphQL Mutations

mutation {
  insert_products(objects:[{name: "Product 1", image: "product1.jpg"}]) {
    id
  }
}

GraphQL Subscriptions >

GraphQL Subscription allows you to subscribe to real-time data from a GraphQL server. This allows an app to subscribe to "events" or "live results" from the backend service while allowing you to control the "shape" of the event from your app.

The subscription can also have nested data to fetch type user, the user id, and user type to know about who placed the order in the same response.

Learn more about GraphQL Subscriptions

subscription {
  orders (where: {id: {_eq: "XX-12"}}) {
    id
    payment
    dispatched
  }
}

Fullstack GraphQL Tutorial Series

The following fullstack GraphQL tutorials will teach you how to build realtime todo apps using authenticated GraphQL APIs

Apollo Client
GraphQL with NextJS

In this fullstack tutorial, we will look at building a Hasura GraphQL Backend to generate APIs, followed by integration with Next.js app. We'll be using Auth0 for the Authentication and Vercel for deployment.

Native GraphQL Client
RxDB Offline First Tutorial

In this course, we will look at how to make a web app offline first using a client-side database that is synced securely with Postgres. We'll be using two open-source tools, RxDB and Hasura to help set up the sync. We will be using Auth0 for Authentication though other tools like Firebase, AWS Cognito or AuthGuardian should also work perfectly well.

FAQs

Are these tutorials free?

Absolutely! All of our GraphQL Tutorials are free and open source.

Who can take these tutorials?

All frontend / backend / fullstack developers can take these tutorial series to build real-world applications.

Will there be example code snippets or links to documentation?

All the tutorials will have the full source code available in the open-source hasura/learn-graphql repo.

GraphQL easy to learn?

Yes! GraphQL is easy to learn and consume on the client. However, building a custom GraphQL Server following best practices can be difficult for developers coming from REST API background.

What front end clients are being used in the tutorials?

Most of the frontend frameworks use Apollo Client for the integration. We are planning to add more tutorials around other clients like Urql.

What technologies are used in the tutorials?

Technology choices are mostly wide open. The javascript libraries used can be replaced with an equivalent one. The server-side APIs are taken care of by Hasura GraphQL Cloud Service connected to a PostgreSQL database.

Is GraphQL frontend or backend?

GraphQL is just a query language spec and there are implementations on both client and server.

What language is GraphQL written in?

GraphQL is language agnostic. Reference implementations for the spec have been written in multiple languages, the most popular one being in javascript.
