Fitfab-UI Component (Rollup, TypeScript, Babel, React styled-components)

With this release, I target ES6 JavaScript. ES6 is much closer to TypeScript and produces less code, which means faster loading times.

• This Library is meant to be used in modern browsers -- It doesn't support IE11.
• Other decisions: read more here

peerDependencies:

• react@^16.8.4
• react-dom@^16.8.4
• styled-components@^4.1.3

install

yarn add fitfab-ui

usage

import { prettyDate } from 'fitfab-ui'
const pretty = prettyDate('8/2/2019')
// pretty should be: 'August 2 2019'

See the Storybook setup

Using local copy of fitfab-ui

NPM LINK

• from the root of 'fitfab-ui' run: npm link
• from the root of your app run: npm link fitfab-ui

Then start using as normal:

import { Button } from 'fitfab-ui'

Script CMD explained.

NPM CMD: read about npm scripts

"prepublishOnly": "npm test && npm run lint"

• This run BEFORE the package is prepared and packed, ONLY on npm publish.

• A good place to verify that linting rules and tests are passing.

Rollup TypeScript & Babel setup

• Microsoft TypeScript Babel Setup

• Styled-components: babel-plugin-styled-components

Jest & Enzyme setup

NOTE: make sure that jsx is set to react { "jsx": "react" } within the tsconfig.json file.

• Reference: React TS Jest Enzyme Setup

Jest & React testing library setup

• create the file rtl.setup.ts

// See https://github.com/kentcdodds/react-testing-library#global-config
import '@testing-library/react/cleanup-after-each'
import 'jest-dom/extend-expect'

• Then add it to jest.config.js -- on this project I have a /config folder where the rtl.setup.ts lives.

    /***
     * Setup React-testing-library
     */
    setupFilesAfterEnv: ['<rootDir>/config/rtl.setup.ts'],

• Reference: @testing-library/react
• CheatSheet: @testing-library/react

Three-Shaking Gotcha

if you were to use export default , the bundle would not be three shaken.

// src/utils.js
export default {
    alert: msg => {
        console.log(msg)
    },
    sum: (x, y) => x + y,
}

// src/main.js
import utils from './utils'

const total = utils.sum(7, 4)
console.log(`This is the total: ${total}`)

The code will include alert eventhough it was NOT use in the main.js file.

Husky & lint-staged update 2021

• npx husky-init && npm install

  Note: Husky will create a prepare script command within package.json

• npx mrm@2 lint-staged

  This command will install and configure husky and lint-staged depending on the code quality tools from your project's package.json dependencies

creating a new husky hooks

• npx husky add .husky/pre-push 'npm test'

  Note: add the pre-push hook to only run the tests when pushing

• npx husky add .husky/commit-msg 'message'

  Note: This is to enforce Conventional Commits specification
