### 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 modules, we added a commenting system to a sample blog
application. But what if we want to add comments to multiple applications? We
could need to copy-paste the hook to different projects. However, we can also
publish the hook as an NPM library and import it into any project. That is what
we'll do in this lesson, and it's going to take just a few steps!

To deploy our hook as an NPM package, we need to use a bundler.

 is a tool that bundles JavaScript or TypeScript modules
into a single JavaScript file that can be executed in the browser.

TypeScript support out of the box, and it's pretty straightforward to set up.

We can install it with the following command:

Since we're publishing the package from the same place where we have the blog
application, we will add a separate tsconfig specifically for the library.

source code to the

Now, we can try and run it with the following command:

### Bundling

To deploy our hook as an NPM package, we need to use a bundler.

> A **module bundler** is a tool that bundles JavaScript or TypeScript modules

We're going to use [Microbundle](https://github.com/developit/microbundle),
which is a _zero-configuration bundler for tiny modules_. It comes with
TypeScript support out of the box, and it's pretty straightforward to set up.

We can install it with the following command:

    yarn add -D microbundle

Before we use it, let's fill a few things in the `package.json`:

-   `"name": "@anemone/newline-use-comments"` — the package name. I'm prefixing it
    with my NPM username `@anemone`.
-   `"source": "lib/useComments.ts"` — the source code.
-   `"main": "dist/index.js"` — the location where Microbundle should generate the
    CommonJS bundle.
-   `"types": "dist/useComments.d.ts"` — TypeScript types location. Microbundle
    will generate types from our module and put them there.
-   `"module": "dist/index.esm.js"` — the location where the
    [ESM](https://nodejs.org/api/esm.html) bundle should be placed
-   `"files": [ "dist" ]` — files that should be included in the package. We want
    to ignore all the blog application code.
-   `"version": "0.0.1"` — the version of our package. Feel free to set a
    different number.
-   `"private": false` — otherwise we won't be able to publish the library.

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