Mini react component library

This project skeleton is taken from this article to get started with creating React component library (https://blog.harveydelaney.com/creating-your-own-react-component-library/) and (https://github.com/HarveyD/react-component-library)

Stacks used in this library

Development

Testing

npm run test

Building

npm run build

Storybook

Run storybook in your local machine

npm run storybook

Generating New Components

I've included a handy NodeJS util file under util called create-component.js. Instead of copy pasting components to create a new component, you can instead run this command to generate all the files you need to start building out a new component. To use it:

npm run generate YourComponentName

This will generate:

/src
  /YourComponentName
    YourComponentName.tsx
    YourComponentName.stories.tsx
    YourComponentName.test.tsx
    YourComponentName.types.ts
    YourComponentName.scss

The default templates for each file can be modified under util/templates.

Don't forget to add the component to your index.ts exports if you want the library to export the component!

Installing Component Library Locally

Let's say you have another project (test-app) on your machine that you want to try installing the component library into without having to first publish the component library. In the test-app directory, you can run:

npm i --save ../react-component-library

which will install the local component library as a dependency in test-app. It'll then appear as a dependency in package.json like:

  ...
  "dependencies": {
    ...
    "react-component-library": "file:../react-component-library",
    ...
  },
  ...

Your components can then be imported and used in that project.

NOTE: After installing the component library locally, you may run into:

Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:

You might have mismatching versions of React and the renderer (such as React DOM)
You might be breaking the Rules of Hooks
You might have more than one copy of React in the same app See for tips about how to debug and fix this problem.

This is the most commonly encountered problem people face when installing the library locally. This is most likely due to the third reason: You might have more than one copy of React in the app.

Normally when a library is published, dev dependencies are excluded. However, when the library is symlinked, all local dev depdendencies are persisted in the libraries node_modules (includes React). Your bundler may see two versions of React, one in the consuming app and one in the symlinked library. The solution is to have the component library use the React version in the consuming app. So from your component library folder, run:

npm link ../test-app/node_modules/react
