### 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

In the previous module, we covered the backend part of our course. We have a
database that can store the comments, and we learned few bits about GraphQL and
Hasura. We also mentioned that we're going to connect to Hasura via GraphQL to
add and retrieve comments, and that's what we're going to focus on in this
module.

We will integrate with Hasura from within a frontend application. In the
following lessons, we will create a custom React hook that will have the logic
responsible for sending POST requests with GraphQL queries and mutations.

However, we need a sample application that we can use to demonstrate the
commenting system. We'll go with a simple blog as it perfectly fits the comments
use-case.

 is a frontend framework created on top of React,
enabling server-side rendering and creating static websites (e.g., blogs).

We introduced two new terms — let's quickly see what they mean:

We're going to use the
[Next.js blog starter](https://github.com/vercel/next.js/tree/canary/examples/blog-starter-typescript)
as it's pretty simple and lets us get started quickly.

[Next.js](https://nextjs.org/) is a frontend framework created on top of React,
enabling server-side rendering and creating static websites (e.g., blogs).

We introduced two new terms — let's quickly see what they mean:

> **Server-side rendering**: A typical React application renders its content on

This course doesn't require knowledge about Next.js, but if you want to learn
more about Next itself, you can check out
[Next.js docs](https://nextjs.org/docs/getting-started).

### Setting up the sample app

In the
[Next.js blog starter](https://github.com/vercel/next.js/tree/canary/examples/blog-starter-typescript)
repository, we can see setup instructions. Let's use the first command:

```sh
npx create-next-app --example blog-starter-typescript blog-starter-typescript-app
```

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.
