react-external-lib-boilerplate v0.1.6

React Standalone Component Boilerplate

A boilerplate for developing standalone React components with Storybook and publishing them to npm.

Features

• Rollup: Provides build with esm,cjs,.d.ts.
• Release-it: Github releases, npmjs publishing
• Storybook: Local development , deployment to Github Pages (optionally).

Out the box support:

• TypeScript: Pre-configured for seamless integration.
• Material-UI: Compatible with MUI v5/v6.
• SDLC: There is a set of github actions, aims to implement gitflow model

Getting Started

Prequirements

• NPM publish token

  Follow these steps if you're planning to push to npmjs/other registry

  • Generate an npm token:

    • Go to npmjs.com, log in, and navigate to Access Tokens.
    • Create a new token of type Classic, and choose the Automation option.

  • Test locally (⚠️ will override ~/.npmrc ⚠️):

    # make a backup before testing ci token in local env
    
    # backing up
    # $ cp ~/.npmrc ~/.npmrc.bak
    
    $ npm config set //registry.npmjs.org/:_authToken $NPM_PUBLISH_TOKEN
    $ npm publish
    
    # restoring
    # $ mv ~/.npmrc.bak ~/.npmrc

  • GitHub Actions setup:

    Add the NPM_PUBLISH_TOKEN as a secret in your GitHub repository/organization if you want to push releases via GitHub Actions.

• Storybook deploying to Github Pages

  1. Go to Repository Settings -> Actions -> General -> Workflow permissions, enable Read and write permissions and Save.

  2. Go to Repository Settings -> Pages -> Build and deployment, and set the Source to GitHub Actions.

• PR Labels

  • Create next labels: patch minor major

  • When creating PR select release type, it will update version as requested (patch is default if not selected)

Installation

To create a new project from this template:

1. Click on the Use this template button in GitHub.

2. Clone the newly created repository:

   git clone git@github.com:yourusername/your-custom-lib.git
   cd your-custom-lib
   yarn install
   yarn storybook
   yarn build
   yarn release # make sure you have a valid NPM_PUBLISH_TOKEN
   
   # ci env simulate
   # yarn release --ci  --increment=patch

Material UI

For creating custom MUI components, install the needed dependencies

$ yarn add @mui/material @emotion/react @emotion/styled @mui/icons-material @fontsource/roboto

Storybook MUI setup (typescript, theme swithcing, etc):

• Integrate Material UI with Storybook

Development

• NO SDLC/GITHUB ACTIONS
  • don't create gitflow branches like feature/*, hotfix/*, release/* , so no actions would be triggered
  • yarn build
  • release-it update:
    • yarn release (for non-interactive: yarn release --ci --increment=patch)
  • manual update:
    • yarn version --patch

    • yarn publish

• SDLC:

  • gitflow:

    • Push to feature/*, hotfix/*

      • triggers .github/workflows/tests.yml
      • TODO: create prerelease if there is an open PR from this branch (so the prerelease can be installed via npm, may be helpful for integration tests/qa).

    • Make PR to development

      • Set label: patch,minor,major (necessary for calculating next version)
      • triggers .github/workflows/semver-check.yml when saved (checks if label above was set)
    • When merged:
      • triggers .github/workflows/release.yml
        • new tag created
        • new github release created
        • new build pushed to npmjs

        • new commit pushed to development (⚠️ fails on protected branches )

    - TODO: support dev/rc tags

Available Scripts

Here are the main scripts you can use:

yarn storybook

yarn test

Runs the test suite using react-scripts.

yarn build

Builds the component library using Rollup, outputting both esm and cjs formats.

yarn release

Prepares and publishes a new version to npm.

Configuration

TypeScript (tsconfig.json)

The provided tsconfig.json contains several options related to generated .d.ts - required by rollup-plugin-dts

• "declaration": true
• "declarationDir": "build/dts"
• "emitDeclarationOnly": true

Known Issues

• Release-it
  • NPM Classic Token bypasses 2FA: The token used for automated publishing bypasses two-factor authentication.
  • GitHub Actions fail on protected branches: If git.commit === true in the release-it configuration, the release.yml action will fail on protected branches. To resolve this, disable branch protection for the default branch. TODO: refactor flow without commiting to default branch
