Create React Component Module

• npm install -D react react-dom typescript @types/react
• npx tsc --init
• Modify tsconfig.json

{
  "include": ["src"],
  "exclude": [
    "dist",
    "node_modules"
  ],
  "compilerOptions": {
    "module": "esnext",
    "lib": ["dom", "esnext"],
    "importHelpers": true,
    "declaration": true,
    "sourceMap": true,
    "rootDir": "./src",
    "outDir": "./dist/esm",
    "strict": true,
    "noImplicitReturns": true,
    "noFallthroughCasesInSwitch": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "moduleResolution": "node",
    "jsx": "react",
    "esModuleInterop": true,
    "skipLibCheck": true,
    "forceConsistentCasingInFileNames": true,
  }
}

• Modify package.json:

{
  "name": "PACKAGE_NAME",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "build": "tsc"
  },
  "keywords": [],
  "author": "YOUR_NAME",
  "license": "ISC",
  "devDependencies": {
    "@types/react": "^18.0.12",
    "react": "^18.1.0",
    "react-dom": "^18.1.0",
    "typescript": "^4.7.3"
  }
}

• Create sample components in src/components
• Create index.ts inside src and export your components there.
• npm run build, should generate a dist folder at the root.
• git init and Create .gitignore file with contents of:

/node_modules
/dist
# Ignore test-related files
/coverage.data
/coverage/

# Build files

• npm install -D eslint eslint-plugin-react eslint-plugin-react-hooks @typescript-eslint/eslint-plugin @typescript-eslint/parser for linting
• Create an .eslintrc file at the root with content of:

{
  "root": true,
  "extends": [
    "eslint:recommended",
    "plugin:react/recommended",
    "plugin:@typescript-eslint/eslint-recommended",
    "plugin:@typescript-eslint/recommended"
  ],
  "parser": "@typescript-eslint/parser",
  "plugins": [
    "@typescript-eslint",
    "react",
    "react-hooks"
  ],
  "rules": {
    "react-hooks/rules-of-hooks": "error",
    "react-hooks/exhaustive-deps": "warn",
    "@typescript-eslint/no-non-null-assertion": "off",
    "@typescript-eslint/ban-ts-comment": "off",
    "@typescript-eslint/no-explicit-any": "off"
  },
  "settings": {
    "react": {
      "version": "detect"
    }
  },
  "env": {
    "browser": true,
    "node": true
  },
  "globals": {
    "JSX": true
  }
}

• Create .eslintignore, with content of:

/node_modules
/dist

• Modify package.json, add to script command:

"lint": "eslint \"{**/*,*}.{js,ts,jsx,tsx}\""

• npm run lint, for testing lint
• npm install -D eslint-config-prettier eslint-plugin-prettier prettier, for prettier.
• Create .prettierrc.json, with content of:

{
  "bracketSpacing": true,
  "singleQuote": true,
  "trailingComma": "all",
  "tabWidth": 2,
  "semi": false,
  "printWidth": 120,
  "jsxSingleQuote": true,
  "endOfLine": "auto"
}

• Modify .eslintrc, reference:

"plugins": [
  "@typescript-eslint",
  "prettier",
  "react",
  "react-hooks"
],
"extends": [
  "prettier",
  "plugin:prettier/recommended",
  "eslint:recommended",
  "plugin:react/recommended",
  "plugin:@typescript-eslint/eslint-recommended",
  "plugin:@typescript-eslint/recommended"
],

• npm run lint, testing lint again.
• Modify package.json script command:

"prettier": "prettier --write \"{src,tests,example/src}/**/*.{js,ts,jsx,tsx}\""

• Well, test linting again.
• npm install -D jest jest-canvas-mock jest-environment-jsdom ts-jest @types/jest @testing-library/react
• npm install --save-dev identity-obj-proxy css-loader
• Create jestconfig.json file at the root, with the content of:

{
  "transform": {
    "^.+\\.(t|j)sx?$": "ts-jest"
  },
  "testRegex": "(/tests/.*|(\\.|/)(test|spec))\\.(jsx?|tsx?)$",
  "moduleFileExtensions": ["ts", "tsx", "js", "jsx", "json", "node"],
  "testEnvironment": "jsdom",
  "moduleNameMapper": {
    "\\.(scss|css)$": "identity-obj-proxy"
  }
}

• Create tests folder, with a file sample.test.tsx.

import * as React from 'react'
import { render } from '@testing-library/react'

import 'jest-canvas-mock'

import { Sample } from '../src'

describe('Common render', () => {
  it('renders without crashing', () => {
    render(<Sample />)
  })
})

• Modify package.json script command:

"test": "jest --config jestconfig.json"

• Modify package.json script command:

"build": "npm run build:esm && npm run build:cjs",
"build:esm": "tsc",
"build:cjs": "tsc --module commonjs --outDir dist/cjs",

• Modify package.json, content of:

"main": "./dist/cjs/index.js",
"module": "./dist/esm/index.js",
"types": "./dist/esm/index.d.ts",

"repository": {
  "type": "git",
  "url": "git+https://github.com/KenReyMozo/kenrey-ui.git"
}

"peerDependencies": {
  "react": ">=16",
  "sass": ">=1.69.5"
}

"files": [
  "dist",
  "LICENSE",
  "README.md"
]

"keywords": [
  "kenrey-project",
  "kenrey-ui",
  "kenrey-component"
]

"license": "MIT",

• npm login

• npm publish --dry-run

• npm publish

• To add automated build:

• at the root, Create .github/workflows/publish.yml, wit the contents:

# This is a name of the workflow
name: build
# Controls when the workflow will run
on:
  # Triggers the workflow on published releases
  release:
    types: [published]
# A workflow run is made up of one or more jobs that can run sequentially or in parallel
jobs:
  # This workflow contains a single job called "build"
  build:
    # The type of runner that the job will run on
    runs-on: ubuntu-latest
    # Steps represent a sequence of tasks that will be executed as part of the job
    steps:

      - name: Checkout
        # Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it
        uses: actions/checkout@v3

      - name: Setup Node
        # Setup node environment
        uses: actions/setup-node@v3
        with:
          # Node version. Run "node -v" to check the latest version
          node-version: 16.x
          registry-url: https://registry.npmjs.org/

      - name: Install dependencies
        run: yarn && yarn install

      - name: Build
        run: yarn build

      - name: Publish
        run: yarn publish

        env:
          # We need this to our NPM account
          NODE_AUTH_TOKEN: ${{ secrets.KENREY_UI_AUTOMATION_TOKEN }}

• NPM Setup:
• settings -> access tokens
• Generate New Token
• Copy the token
• GITHUB Setup:
• Repo -> settings
• Secrets -> Actions
• New repository secret
• Paste the token
• NOTE: secrets.SECRET_NAME_YOU_SET_IN_GITHUB

FOR HANDLING PLAIN CSS

• npm install --save-dev css-loader style-loader
• Modify package.json, added new command and update build command:

"scripts": {
  "build": "npm run build:esm && npm run build:cjs && npm run build:css-components && npm run build:css",
  "build:esm": "tsc",
  "build:cjs": "tsc --module commonjs --outDir dist/cjs",
  "build:css-components": "cp src/components/*.css dist/cjs/components && cp src/components/*.css dist/esm/components",
  "build:css": "cp src/index.css dist/cjs/ && cp src/index.css dist/esm/",
  // Other scripts...
}

• Make one entry point for your css files:
• put your css files in one folder
• create index.css in src, beside the index.ts:
• import your css files to the index.css with @import '<css-dir>'
• After installing the package, import your entry point css file to your app.ts:

import 'your-package-name/dist/cjs/index.css';

FOR HANDLING SCSS FILE / TEMPORARY

• npm install -D node-sass
• Modify package.json, add new command:

"scss": "node-sass src/scss -o src/components"
