Lean React Project With Parcel

Open the terminal and run the commands bellow. I use Yarn, but obviously npm works just as well if you want to follow along.

$ mkdir react-parcel-demo
$ cd react-parcel-demo
$ yarn init -y
$ yarn add react react-dom
$ yarn add -D parcel-bundler babel-preset-react babel-preset-env
$ mkdir src
$ touch src/index.html
$ touch src/index.js
$ touch .babelrc


Parcel’s tag line is “zero configuration”. This is pretty much true, but two things need to be done.

"scripts": {
"dev": "parcel ./src/index.html",
"build": "parcel build ./src/index.html/"
"presets": ["env", "react"]

Hello World

And now for a wee bit of code. First of all a minimal html page …

<!DOCTYPE html>
<meta charset=”utf-8" />
<title>React Parcel Demo</title>
<div id=”app”></div>
<script src=”./index.js”></script>
import React from "react";
import { render } from "react-dom";
const App = () =>{
return (
<h1>Hello Parcel</h1>
render(<App />, document.getElementById("app"));

Bonus: SASS

I normally use SASS for styling and here Parcel really shines when it comes to simplicity! Obviously you need to install sass and add some styling:

$ yarn add -D node-sass
$ mkdir src/sass
$ touch src/sass/main.scss
$ touch src/main.css
,*::before {
margin: 0;
padding: 0;
box-sizing: inherit;
html {
font-size: 62.5%;
body {
background-color: #ecf0f1;
color: #d35400;
font-family: sans-serif;
font-size: 16px;
line-height: 1.7rem;
padding: 3rem;
h1 {
text-align: center;
margin-top: 5rem;
font-size: 6rem;
import “./sass/main.scss”
