Overview:

This boilerplate allows you to create npm package fast and easy with the following setup:

• Storybook to build your component and see it in action before publishing it to npm.
• Rollup to bundle your package.
• Commitizen to simplify professional commit messages.
• standard-version which will bump package version, create a new release tag with the new version and updates CHANGELOG file.

Installing / Getting Started:

• Install packages pnpm install
• Package JSON:
  • name: add the name of your package.
  • description: add the description of your package.
  • repository => url: add the URL of your package.
  • keywords: add keywords to represent your package (SEO).
  • author: add your name.
  • bugs => url: add issues link of your repository.
  • homepage: add readme link of your repository.
• src/components:
  • Add your component with named export in a directory with the same name of your component and don't forget to add index.ts file in the same directory.
  • Update src/components/index.ts to export your component.
  • Add component stories in a file with this extension ComponentName.stories.tsx following the instructions on storybook site.
  • Add component test in a file with this extension ComponentName.test.tsx.
• run pnpm storybook to see your component during development.
• run pnpm commit to commit your files following conventional commit standards.

Publishing your package:

Create NPM token:

• Log into your npm account.
• Click on Edit Profile button.
• Click on Access Tokens.
• Click on Generate New Token:
  • Click on Classic Token:
    • Enter token name.
    • Select Automation if you will use GitHub actions, select Publish if you will publish you package manually.
    • Click on Generate Token.
    • Copy the generated token and save it somewhere.

Publishing a package with GitHub actions:

• Open your repository on GitHub => settings => Secrets and variables => Actions => New repository secret:
  • Name: NPM_AUTH_TOKEN
  • Secret: paste your npm access token.
• Commit your changes:

  pnpm commit

• Create a new release:

  pnpm semantic-release

  NOTE:
  • If you want to commit and run semantic release at the same time use the following script:

    pnpm release

• push your changes to GitHub to run publish workflow.

Publishing a package manually:

• Run your tests:

  pnpm test

• Run semantic release script to create a new release, bump package version and update CHANGELOG.md file:

  pnpm semantic-release

• Build your package:

  pnpm build-lib

• Navigate to lib directory:

  cd lib

• Publish your npm package:

  npm publish --access public

Setup local NPM registry

• I like to publish my package to a local registry and test it locally before publishing it to NPM.
• We will use verdaccio registry:
  • Pull verdaccio image:

  docker pull verdaccio/verdaccio

  • Run verdaccio container:

  docker run -it --rm --name verdaccio -p 4873:4873 verdaccio/verdaccio

  • Create a new user:

  npm adduser --registry http://localhost:4873/

  • Publish your package after building it:

  npm publish --registry http://localhost:4873/

  • Install your package from your local registry:

  npm install <package_name> --registry http://localhost:4873/

Configuring Prettier:

This build relies on Prettier formatter to enforce code style. And ESLint for identifying problematic patterns found in the code.

• Setting up prettier:

  1- You can find steps on how to set up prettier formatter with WebStorm/PhpStorm here.

  Notes:

  • It's better to use local node_modules version of prettier instead of a global one, to avoid version conflicts (in case the globally installed version does not match the version specified in package.json).

  2- Follow the next steps to set up prettier and eslint in VS Code:

  • Install prettier plugin

  • Install eslint plugin

  • Open VS Code settings CTRL + ,:

    a- Search for formatter => check Format on save

    b- Search for prettier => add .prettierrc in Prettier: Config Path section && check Prettier: Require Config

  3- Please refer to other tutorials if you are using a different IDE.
