Publishing the Code

In this course we’ll build a set of custom reusable hooks, a mini react-hanger clone, essentially going from nothing to a fully-automated publishing pipeline that follows the best practices.  We will cover common Hooks APIs every React developer should know, then dive straight into implementing Custom React Hooks, similar to what you will find in leading React libraries in the open source React ecosystem.

## Why this course
React Hooks promise to eliminate the difficulties of sharing state without writing class-based components. The challenge is that Hooks do away with the lifecycle methods and class-based semantics of state management that many React developers were familiar with.  Learning React Hooks on your own can be time consuming, confusing and frustrating.  With that in mind, The newline Guide to Creating a React Hooks Library, was created to provide a complete tutorial that fully covers React Hooks.  Within a few hours you'll have a strong grasp on React Hooks and how to implement them.

## Course Topics
This course packs practical hands-on-instruction using and building React Hooks, along with the best practices you need to build wider React Hooks libraries others across your organization can use.
The first module provides an overview of the React Hooks library project we’ll build, and we'll set up a complete environment with tools for library development.
The subsequent modules then take you through building with React Hooks and creating your React Hooks library, including:
- Hooks API fundamentals
- Developing custom React Hooks
- How to write reusable React Hooks
- Common React Hooks mistakes to avoid in your code
- Transpilers and bundlers for JavaScript libraries
- Using GitHub Actions to test, build, and lint your library
- Publish your React Hooks library to NPM

We’ll use tools including React, TypeScript, Babel, as well as GitHub Actions to build, test, and package a React Hooks library available for others to download from NPM.  Ultimately, build your own React Hooks library and learn the best practices that will make your code reusable. With these skills, you can contribute more confidently to any React codebase using React Hooks, and make your team more productive.

This course is a complete step-by-step guide to coding custom React Hooks and building a Hooks library from scratch.  Confidently master React Hooks, a transformative update added since React version 16.8, that makes it much easier to reuse code as your React codebase grows.

Using GitHub Actions to test, build, and lint your library

Firstly, we're going to keep this simple and stupid by implementing the build step with a very handy tool named 

, which abstracts away all the complexity of Babel, TypeScript and Rollup under one simple 

 to ensure our library is marked as tree-shakable.

Then let's set up Microbundle. Its setup is pretty straightforward.

Firstly, we're going to keep this simple and stupid by implementing the build step with a very handy tool named **Microbundle**, which abstracts away all the complexity of Babel, TypeScript and Rollup under one simple `microbundle` command.

We can begin by setting `sideEffects: false` in `package.json` to ensure our library is marked as tree-shakable.
