In software development in general, we always tend to reuse some code and extract parts of it that we need in multiple places. Front-end development nor React are not an exception. Therefore, sometimes we want to create React libraries as well. When talking about React, library or package could be anything, e.g. one component, a whole set of them, they could be just UI parts but also include some logic that is repeated.
Chapter #1 Create your library with create-react-library
One very quick and simple way of creating React library is by using create-react-library. We all know about create-react-app
and let’s say create-react-library
is the same thing for creating libraries.
To create a new library simply run:
npx create-react-library <LIBRARY_NAME>
We will call ours bornfight-react-library
so the command would be:
npx create-react-library bornfight-react-library
Take attention to replace this library name with yours in any occurrence in this post.
You will be then asked for a few options as displayed on the image. It’s important to select:
-
typescript
as a template -
yarn
as a package manager - rest can be changed easily later in
package.json
if necessary.
That’s it, you’ve created your own React library.
Run and build your library
Executing in the project root directory:
yarn start
Develop, test and showcase your work
Option A) Using CRA
There is CRA in the example
directory. It is also started by executing:
cd example
yarn start
Option B) Using Storybook
If you prefer using Storybook you can install it additionally to CRA:
cd example
npx sb init
This means you will need to write your stories separately from components.
Stories will be located in the
example
dir, while you write your components in the project root. Otherwise, if you want to install Storybook in the project root, it breaks the CRA and therefore it is not suggested.
Chapter #2 Publishing a npm package created with create-react-library
Publishing React library means publishing node package. You can publish node packages either to a well-known public registry like npmjs.com or any other registry e.g. Github Packages.
Simple scenario publishing usually includes executing:
npm login
npm publish
More about publishing can be found in the rest of the chapter.
I) Publishing as a public package to npm.js registry
1) Ensure you provided correct name and version in package.json
If you want to publish it under your npm organisation (here @bornfight), your changes should look like:
- "name": "bornfight-react-library",
- "version": "1.0.0",
+ "name": "@bornfight/bornfight-react-library",
+ "version": "0.0.1",
Otherwise, if you want to publish it under your account just ignore this step and keep the package name without an organization prefix.
2) Login to your npm account
npm login
You will be then prompted to enter your username, password and email.
3) Publish package
npm publish --access public
If you aren't publishing it under organization, --access public
flag isn't necessary as it will be default option.
II) Publishing as a private package to Github Packages
1) Ensure you provided correct name, version and repository, e.g.
"name": "@bornfight/bornfight-react-library",
"version": "0.0.1",
"repository": "https://github.com/bornfight/bornfight-react-library",
2) Update publish config to point to Github Packages registry
"publishConfig": {
"registry": "https://npm.pkg.github.com"
}
3) Login to your Github
npm login
You will be then prompted to enter your username, password and email.
Use Github personal access token as password.
4) Publish package
npm publish
