What are we going to build? During this lesson, you'll get to know more about the course, the tech stack, and what you're going to learn.

Course Introduction

Introduction

In this lesson, we'll cover the basics of GraphQL; what it is and how to use it. We'll also understand how it fits the course's subject.

Introduction to GraphQL

We'll learn about Hasura and play a bit with its features and writing GraphQL queries. This knowledge will let us move on to the commenting system!

Using Hasura to Generate GraphQL APIs and Protect Data

In this lesson, we'll create a comments table and learn a bit about databases along the way.

How to Create a Comments Database Table and Set Permissions

Storing comments with Hasura

We'll get to know a sample blog application that we'll be adding a comments section to. We'll also go over the setup and explain the directory structure.

Setting Up Next.js Blog Starter and Understanding Its Structure

In this lesson, we'll create a React hook that will fetch the comments from the database. We'll cover how to create a custom hook as well as how to integrate with Hasura.

Fetching Blog Comments from a Database with a Custom React Hook

In this lesson, we'll add a UI for the comments section and a new comment form. We'll also display the comments that we get from the React hook.

A Brief Tutorial on Building the UI for a Blog Comments Section

This lesson will show how to extend the hook to handle adding new comment logic. It will cover adding a new GraphQL mutation and using it from the frontend application.

How to Use GraphQL to Add Comment Features to a Frontend App

Implementing a comments system

We'll learn about optimistic updates and add them to our hook's implementation to improve the user experience.

An Overview of Optimistic Updates for React Hooks

In this lesson, we'll add pagination to both the hook and UI.

Adding Pagination to a Comments Section with Hasura and React

Extending the comments system functionality

This lesson will teach you how to publish a React hook as an NPM library.

How to Publish a Custom React Hook as an NPM Library

Right now, all the comments are public instantly. However, we may want to review the comments before showing them to other users. This is what we'll cover in this lesson.

### The newline Guide to Full Stack Comments with Hasura and React

Build and implement a comprehensive commenting system for your website using Hasura and React.  We’ll use the commenting feature to teach technology concepts like Hasura with appropriate authorization, optimistic updates for a more responsive UI, pagination, and publication of library in NPM.

### Why this course

Many developers would like to add a comments section to their website or blog for users to post comments or hold discussions. While it's possible to use existing hosted solutions such as Disqus or Facebook Comments, they often charge a fee and impose their UI leaving little to no control for modifications or customization. 

Another option is to build your own from scratch — which is what we'll do in this course. We’ll use Hasura, which generates GraphQL API from a database so that the backend part is as easy and the least time-consuming as possible. Along the way, we’re going to learn about databases, GraphQL, building UI components with React and TypeScript, and more.
By the end of this course, you’ll have a commenting system added to a website we’ve called, Why comments?, with all comments stored by Hasura. We'll also publish the fetching and adding comments logic as a library to NPM.

This course focuses on building a commenting widget, however, the skills you’ll acquire will allow you to build any fullstack widget you can think up for your application.  You’ll be able to contribute to fullstack React, GraphQL, and Hasura projects at work, in open source, or your own projects. You'll discover that this stack not only eliminates the need for having large teams of backend developers, but it lets your projects move faster.

### Your Instructors

Hi, I'm Aleksandra, and I'm your instructor for this course. I’m the former tech lead of Hasura console and lead maintainer of Bliz.js. This course combines my knowledge in a few areas such as TypeScript, React, Hasura, GraphQL, and general application development.

Importance of tests, and how to test React components

Congratulations, and thank you for completing the course! By now, you have a
working commenting system that you can reuse on any website.

Let's list down the major things that you learned during the course:

Congratulations, and thank you for completing the course! By now, you have a
working commenting system that you can reuse on any website.

Let's list down the major things that you learned during the course:

-   [GraphQL](https://graphql.org/) — we covered the basics of GraphQL, and we
    wrote a few queries and mutations. We also saw how to send GraphQL requests
    from the client and how to handle the responses.
-   [Hasura](https://hasura.io/) — we learned how to set up a new Hasura instance,
    create tables, configure permissions, and set up unauthorized access.
-   [Custom React hooks](https://reactjs.org/docs/hooks-custom.html) — we wrote a
    custom hook and used it in a component. We also covered how to test it.
-   [Mock Service Worker](https://mswjs.io/) — we learned how to mock GraphQL
    requests for the tests using MSW. This way, when running the tests, we don't
    have to make actual API calls that would edit the database, but we can keep
    everything locally.
-   [Publishing a library to NPM](npmjs.com) — we saw how to bundle our code, set
    up the project before publishing it to NPM, and use the command line to
    publish the library.

HASURA, we learned how to set up a new HASURA instance, create tables,

Custom React hooks, we wrote a custom hook and used it in a component.

MOC service worker, we learned how to mock GraphQL requests for tests using MSW

This way when running the tests we don't have to make actual API calls that

edit the database, but we can keep everything locally.

Publishing a library to npm, we saw how to bundle our code, set up project

it to npm, and use the command line to publish the library.

You can use this knowledge for other full stack problems.

HASURA will be an excellent tool for many use cases and it can save you a lot

Also, I hope that you keep writing tests for your components and an MSW is

We covered a lot in this course and we did a lot of work so we have to be very,

Congratulations for completing the course and I hope that you had a good time
