Creating a Custom React Library
Creating a custom React library can be a great way to share reusable components and functionality across multiple projects. This guide will walk you through the process of setting up and developing a library using the React Library Builder.
Step 1: Set up the Project
First, create a new directory for your library and navigate to it in the terminal. Then, clone the React Library Builder repository using the following command:
git clone https://github.com/flaviodelgrosso/react-library-builder.git cd react-library-builder yarn install
Alternatively, you can download the repository as a zip file of the latest release from here and extract it to your new directory.
Once you have the repository downloaded, navigate to the project directory and run the following command to install the necessary dependencies:
Step 2: Develop Your Components
Now that your project is set up, you can start developing your custom components. In the
src/components folder you can start creating a new component file. For example, if you were creating a button component, you would create a file called
Button.tsx in the
As you develop your components, make sure to update the
src/index.ts file to include them in your library. This will allow other developers to import and use your components in their own projects.
It's also important to include a
YourComponent.story.tsx file for each component you create. This file will allow you to view and test your component in Storybook, a tool for developing and testing UI components.
Step 3: Style Your Components
The React Library Builder supports both SCSS and CSS out of the box, so you can style your components as you normally would. If you want to use CSS modules, you can refer to the rollup-plugin-postcss documentation for more information.
Step 4: Test Your Components
Testing is crucial when developing a library, as it helps ensure that your components work as expected. The React Library Builder uses Vitest and @testing-library/react for testing. You can find an example test file in the
To run the tests, use the following command:
To run the test and show the coverage, use the following command:
Step 5: Linting
Linting is an important step in maintaining code quality, The React Library Builder uses ESLint and eslint-config-prettier for linting. You can modify linting rules by overriding them in the
To run the linter, use the following command:
To automatically fix linting issues, use the following command:
Step 6: Publishing Your Library
When your library is ready, you can publish it to NPM so that others can use it in their own projects. Make sure you have an active account with NPM, and that your
.npmrc file is set up correctly. Also, ensure that the repository URL in the
package.json file is set to your repository URL. Then, use the following command to release your library:
Step 7: Deploy Storybook to GitHub Pages
You can also deploy your Storybook to GitHub Pages to make it easier for others to view and test your components. Make sure the repository URL in the
package.json file is set to your repository URL, then use the following command:
And that's it! You now have a working React library that you can use in your own projects and share with others. Don't forget to refer to the Storybook documentation for information on custom layouts, styling, and more.
