‪“‬In what way is JS any more maintainable than CSS? How does writing CSS in JS make it any more maintainable?”

‪Happy to chat about this. There’s an obvious disclaimer that there’s a cost to css-in-js solutions, but that cost is paid specifically for the benefits it brings; as such it’s useful for some usecases, and not meant as a replacement for all workflows. ‬

‪(These conversations always get heated on twitter, so please believe that I’m here to converse, not to convince. In return, I promise to listen to you too and change my opinions; I’ve had mad respect for you for years and would consider your feedback a gift. Also, some of the stuff I’m writing might seem obvious to you; I’m not trying to tell you if all people of some of the details, but it might be useful to someone else who bumps into this who doesn’t have context)‬

So the big deal about css-in-js (cij) is selectors.

Note:

When this guide is more complete, the plan is to move it into Prepack documentation.
For now I put it out as a gist to gather initial feedback.

A Gentle Introduction to Prepack (Part 1)

If you're building JavaScript apps, you might already be familiar with some tools that compile JavaScript code to equivalent JavaScript code:

Babel lets you use newer JavaScript language features, and outputs equivalent code that targets older JavaScript engines.

	import * as glob from 'glob';
	import * as fs from 'fs';
	import * as path from 'path';

	async function changePackage(ppp: any) {
	try {
	const filesToUpdate: string[] = await new Promise((resolve, reject) => {
	glob(ppp, function(err, files) {
	if (err) return reject(err);
	return resolve(files);

	// Inspired by https://twitter.com/coderitual/status/1112297299307384833 and https://tapajyoti-bose.medium.com/7-killer-one-liners-in-javascript-33db6798f5bf

	// Remove any duplicates from an array of primitives.
	const unique = [...new Set(arr)]

	// Sleep in async functions. Use: await sleep(2000).
	const sleep = (ms) => (new Promise(resolve => setTimeout(resolve, ms)));
	// or
	const sleep = util.promisify(setTimeout);

	(function (context, trackingId, options) {
	const history = context.history;
	const doc = document;
	const nav = navigator \|\| {};
	const storage = localStorage;
	const encode = encodeURIComponent;
	const pushState = history.pushState;
	const typeException = 'exception';
	const generateId = () => Math.random().toString(36);
	const getId = () => {

	import React from 'react';

	export class StateDispatcher extends React.Component {
	constructor(props) {
	super(props);
	this.state = props.state \|\| {};
	this._dispatch = this.dispatch.bind(this);
	}

	dispatch(action) {

	// Node os module
	// The os module provides a number of operating system-related utility methods.
	// It can be accessed using:
	const os = require('os');
	// Using a single monolithic configuration file impacts comprehension and
	// removes any potential for reusability.
	// As the needs of your project grow, you have to figure out the means to manage
	// webpack configuration more effectively.
