JavaScript Write Tree Shaking Friendly Modules (ECMAScript)
April 13, 2022CommonJS modules usually involves module.exports
and require
.
ECMAScript/ES2015/ES6 modules usually involve export
and import
.
NOTE: I believe ECMAScript/ES6
is better for size optimization / tree-shaking as compared to CommonJS
, but I might be wrong.
Sample ECMAScript/ES6 modules: ~/libs/client.js
// import RelativeTime from '@yaireo/relative-time'
export function simpleSlugify(str) {
return str.toLowerCase()
.replace(/\s+/g, '-') // Replace spaces with -
.replace(/[^\w\-]+/g, '') // Remove all non-word chars
.replace(/\-\-+/g, '-') // Replace multiple - with single -
.replace(/^-+/, '') // Trim - from start of text
.replace(/-+$/, ''); // Trim - from end of text
}
export function isMobile() {
if (/iPhone|iPad|iPod|Android/i.test(navigator.userAgent))
return true
return false
}
export function ago(date) {
// I am not sure if this approach will work well (or made it worse)
const RelativeTime = require('@yaireo/relative-time')
const relativeTime = new RelativeTime();
return relativeTime.from(date)
}
export default {
simpleSlugify, isMobile, ago
}
How to import
import { extractDomain } from '~/libs/client'
NOTE: I am using Nuxt, which uses Webpack for tree-shaking.
