# create-react-library
> CLI for creating reusable, modern React libraries using Rollup and create-react-app.
[](https://www.npmjs.com/package/create-react-library) [](https://travis-ci.com/transitive-bullshit/create-react-library) [](https://standardjs.com)
## Intro
## Features
- Easy-to-use CLI
- Handles all modern JS features
- Bundles `cjs` and `es` module formats
- [create-react-app](https://github.com/facebookincubator/create-react-app) for example usage and local dev
- [Rollup](https://rollupjs.org/) for bundling
- [Babel](https://babeljs.io/) for transpiling
- [Jest](https://facebook.github.io/jest/) for testing
- Supports complicated peer-dependencies
- Supports CSS modules
- Optional support for TypeScript
- Sourcemap creation
- Hundreds of public modules created
- Thorough documentation :heart_eyes:
- [Chinese docs](./readme.zh-CN.md) by [@monsterooo](https://github.com/monsterooo)
## Install
This package requires `node >= 4`, but we recommend `node >= 8`.
```bash
npm install -g create-react-library
```
## Creating a New Module
```bash
create-react-library
```
Answer some basic prompts about your module, and then the CLI will perform the following steps:
- copy over the template
- install dependencies via yarn or npm
- link packages together for local development
- initialize local git repo
At this point, your new module should resemble this screenshot and is all setup for local development.
## Development
Local development is broken into two parts (ideally using two tabs).
First, run rollup to watch your `src/` module and automatically recompile it into `dist/` whenever you make changes.
```bash
npm start # runs rollup with watch flag
```
The second part will be running the `example/` create-react-app that's linked to the local version of your module.
```bash
# (in another tab)
cd example
npm start # runs create-react-app dev server
```
Now, anytime you make a change to your library in `src/` or to the example app's `example/src`, `create-react-app` will live-reload your local dev server so you can iterate on your component in real-time.

#### Publishing to NPM
```bash
npm publish
```
This builds `cjs` and `es` versions of your module to `dist/` and then publishes your module to `npm`.
Make sure that any npm modules you want as peer dependencies are properly marked as `peerDependencies` in `package.json`. The rollup config will automatically recognize them as peers and not try to bundle them in your module.
#### Deploying to Github Pages
```bash
npm run deploy
```
This creates a production build of the example `create-react-app` that showcases your library and then runs `gh-pages` to deploy the resulting bundle.
## Examples
### Multiple Named Exports
Here is a [branch](https://github.com/transitive-bullshit/react-modern-library-boilerplate/tree/feature/multiple-exports) which demonstrates how to use multiple named exports. The module in this branch exports two components, `Foo` and `Bar`, and shows how to use them from the example app.
### Material-UI
Here is a [branch](https://github.com/transitive-bullshit/react-modern-library-boilerplate/tree/feature/material-ui) which demonstrates how to make use of a relatively complicated peer dependency, [material-ui](https://github.com/mui-org/material-ui). It shows the power of [rollup-plugin-peer-deps-external](https://www.npmjs.com/package/rollup-plugin-peer-deps-external) which makes it a breeze to create reusable modules that include complicated material-ui subcomponents without having them bundled as a part of your module.
### Boilerplate
The CLI is based on this [boilerplate](https://github.com/transitive-bullshit/react-modern-library-boilerplate), which you can optionally read about [here](https://hackernoon.com/publishing-baller-react-modules-2b039d84bce7).
