In this course, we'll cover what it takes to write, maintain, and publish a React library from scratch. 
In the 2020 State of JS survey, an annual survey conducted of the frontend JavaScript community, React came in as the most used framework for frontend development. Because React is so popular, building libraries in it can open you up to a wide range of users, contributors, and possibilities!

## Why this course

Building a library is so much more than just the code. 
We need to know the ins and outs of versioning, deploying, building, documenting, dependency management, module types, tooling, and more. 
This is a daunting task for just one tutorial to cover. Creating React Libraries from Scratch will teach you everything you need to know to succeed in creating a library.

Don't worry if you're not a React wizard. This course is designed for beginner/intermediate developers who have never deployed a library before and have minimal React experience. However, you should be familiar with JavaScript.

## Course Topics
 
Throughout Creating React Libraries from Scratch we'll develop a React Hook called Scroller that will provide a utility for scrolling around web pages—taking advantage of window.scrollTo. 
We'll start in module 1 with an empty directory; adding documentation files, installing dependencies, and setting up GitHub. Right away, you'll have a project that could be deployable as a fully functional library!
In module 2 we'll implement scroller while taking advantage of Storybook to visually test our code. By module 3 Scroller will be deployed to npm in multiple JavaScript module formats.
Finally, in module 4, we'll look at different tools and techniques in software development to maintain a library. This includes linting, unit tests, TypeScript, and Lint-Staged!
By the end of this course, you'll be able to run _npm install scroller_, and take advantage of React code __you__ wrote in future projects.

Creating React Libraries from Scratch will dive into:
- initializing a new npm package
- maintaining code quality
- publishing to npm
- keeping contributors on track
- exposing modules that work in NodeJS and the Web
- unit-testing
- Storybook for demoing components
- exposing typing using TypeScript
- and more!

In this course we'll cover what it takes to maintain, write, and publish a React library from scratch.

For this course, we'll need a few packages installed on our computer.

I use Windows, Powershell, Firefox, and Visual Studio Code for development. All the packages we need can be installed on any operating system, but I'll be showing you how to install them using Windows. Refer to each package's website for information on how to install them on macOS or Linux.

NodeJS is a JavaScript runtime that allows us to execute JavaScript on our computer without a web browser. Out of the box, installing NodeJS will also install npm (Node Package Manager). We'll be using these technologies heavily, so let's get them installed.

, download the latest long-term-support (LTS) installer for your operating system, and follow the installation wizard. If you prefer using a package manager refer to the NodeJS

This course will require:

-   NodeJS/npm
-   Yarn
-   Git
-   A web browser (Chrome, Firefox, Edge, etc)
-   A terminal (Bash, Powershell, ZSH, etc)
-   A code editor (VSCode, Vim, Emacs, etc)

## NodeJS/npm

NodeJS is a JavaScript runtime that allows us to execute JavaScript on our computer without a web browser. Out of the box, installing NodeJS will also install npm (Node Package Manager). We'll be using these technologies heavily, so let's get them installed.

Navigate to the [NodeJS website](https://nodejs.org/en/download/), download the latest long-term-support (LTS) installer for your operating system, and follow the installation wizard. If you prefer using a package manager refer to the NodeJS [package manager documentation](https://nodejs.org/en/download/package-manager).

Once the installation is complete, open a terminal and run `node -v` to check if NodeJS is installed.

## Yarn

Yarn is a package and project manager. Think of Yarn as an extension to npm. In this course, we'll use Yarn v1, though much of the same workflows and commands will work in Yarn v2.

To [install Yarn](https://yarnpkg.com/getting-started/install), run `npm install -g yarn` in a terminal. Run `yarn -v` once the installation is complete. If a version is given then Yarn is successfully installed.

![The terminal showing Yarn installed](https://d2uusema5elisf.cloudfront.net/courses/creating-react-libraries-from-scratch/module_01/lesson_02/public/yarn-install.png)

## Git

Git is a very popular distributed version control system that keeps a history of our code changes. We'll use Git to allow multiple contributors to work on a single codebase, and as a way to communicate with GitHub.

Install Git by [navigating to the Git website, and click download.](https://git-scm.com/downloads)

![The terminal showing Git installed](https://d2uusema5elisf.cloudfront.net/courses/creating-react-libraries-from-scratch/module_01/lesson_02/public/git-version.png)

## Visual Studio Code (VSCode)

Visual Studio Code is an Integrated Development Environment (IDE) with a wide range of extensions and helpful autocorrect features.

Install VSCode by [navigating to the VSCode website, and clicking download.](https://code.visualstudio.com/).
