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 beginners 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.

Welcome to Creating React Libraries from Scratch! I'm Dylan Paulus, a Lead Software Engineer working on full-stack applications for critical infrastructure. An area I see engineers struggle with is how to share React code. Rightly so! There are a lot of moving pieces in frontend development. I'm excited about this course to help narrow the gap between an empty directory to a fully managed React library in Node Package Manager (npm).

In this course we'll take a deep dive into creating React libraries from scratch, writing a very practical library we're going to call Scroller, an easy-to-use React website scrolling library. The implementation of Scroller will be minimal. We'll be spending our time in this course learning how to create, publish, and maintain ReactJS libraries. The codebase we'll be creating has a focus on React, but many of the topics we'll be covering could be used in any NodeJS or JavaScript project.

## Background

React is a framework developed by Facebook to make developing user interfaces (UI) easier. In the [2020 State of JS survey](https://2020.stateofjs.com/en-US/technologies/front-end-frameworks/), an annual survey conducted of the frontend JavaScript community, React came in as the most used framework for frontend development.
