### 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

Welcome to Newline Guide to Fullstack Comments with React and Hasura! In this
course, we'll explore how to implement a commenting system and add it to a
website. Along the way, we're going to learn about databases, GraphQL, Hasura,
building UI components with React and TypeScript, and a few other things.

Why comments? Many developers would like to add a comments section for their
websites or blogs to gather feedback from their visitors. While it's possible to
use existing, hosted solutions, they are mostly paid and impose fixed UI. We
also have little to no control over it.

Another option is building it from scratch — and this is what we're going to do
in this course. By the end, we'll have a commenting system added to a website
and comments stored in a database managed by Hasura. We'll also publish the
fetching and adding comments logic as a library to NPM.

The goal of this course is to empower you, a frontend developer, to build your own
full-stack solutions. By teaching how to add a comments widget to a website,
we'll strive to make this knowledge transferable to other similar problems that
require a database and integration from a frontend application.

### This course mission

The goal of this course is to empower you, a frontend developer, to build your own
full-stack solutions. By teaching how to add a comments widget to a website,
we'll strive to make this knowledge transferable to other similar problems that
require a database and integration from a frontend application.

### Outline

This course is split into four modules:

**Module 1**: Storing comments with Hasura

**Module 2**: Implementing a comments system

**Module 3**: Extending the comments system functionality

**Module 4**: (Bonus) Publish a library to NPM and various customizations

### Tech Stack

-   Frontend: [React](https://www.reactjs.org) and
    [TypeScript](https://www.typescriptlang.org) — we'll be implementing comments
    UI and backend integration logic in a React application written in TypeScript
-   Database: [Postgres](https://www.postgresql.org/) — we'll be storing comments
    there
-   Backend: [Hasura](https://hasura.io/) — it will generate APIs from the
    database
-   [GraphQL](https://graphql.org/): as Hasura generates GraphQL APIs, we're going
    to use GraphQL from the frontent to communicate with it

### Who is this course for?

This course is for React developers who want to learn how to add full-stack
components to their websites. This course assumes a basic React knowledge:

-   You should know what a React component is and be reasonably confident in
    implementing one
-   You should be familiar with `useState`, and `useEffect` React hooks
