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.

 is a tool for viewing and interacting with UI (user interface) components. There are plugins for a wide array of frameworks including React, Angular, Vue, and many more. Storybook gives us a sandbox to test our React code. It also gives us a nice website we could publish to our users to allow them to demo our library! We'll be utilizing Storybook to check that 

 is working correctly without needing to deploy our library.

Get started setting up Storybook by using their initialization installer

## What is Storybook?

[Storybook](https://storybook.js.org/) is a tool for viewing and interacting with UI (user interface) components. There are plugins for a wide array of frameworks including React, Angular, Vue, and many more. Storybook gives us a sandbox to test our React code. It also gives us a nice website we could publish to our users to allow them to demo our library! We'll be utilizing Storybook to check that `useScroller` is working correctly without needing to deploy our library.

## Setting up Storybook

Get started setting up Storybook by using their initialization installer `npx sb init` at the root of Scroller. `npx` is a tool which comes with npm for running scripts found in `node_module/.bin` or remotely. If a script isn't found locally, `npx` will download the required scripts from npm and run it. `sb` is a Storybook initialization script. `sb` will scan our project for the correct frontend framework to use, in our case React, and add Storybook to Scroller's `devDependencies`.

A `stories/` directory is automatically created in the `src/` directory.

In the `stories/` directory, delete all the files contained within. These are all autogenerated files created by `sb init` which we'll be replacing.

<Directory module="03" lesson="03">
    <Folder header="scroller">
        <Folder isHighlighted header=".storybook">
            <File isHighlighted>main.js</File>
            <File isHighlighted>preview.js</File>
        </Folder>
        <Folder header="node_modules" isClosed>
            <em style={{ color: "rgba(0, 0, 0, 0.6)" }}>Dependencies installed from yarn get added here.</em>
        </Folder>
        <Folder header="src">
            <Folder isHighlighted header="stories" />
            <File>index.js</File>
            <File>useScroller.js</File>
        </Folder>
        <File>CONTRIBUTING.md</File>
        <File>LICENSE.md</File>
        <File>README.md</File>
        <File>package.json</File>
        <File>yarn.lock</File>
        <File>.gitignore</File>
    </Folder>
</Directory>

## Writing our first story

Create a new file called `useScroller.stories.js` inside the `src/stories` directory. Files suffixed with `.stories` tell Storybook which files to look for when generating its own files. A story is a place to visually share and test frontend code. We can have a group of stories for a single component to show different implementations of a component. Or, create one story per component.

Setup Storybook to view and test our code.

do we have to install anything for sb to work?
