Simplifying SCSS Compilation with Parcel.js

Creating an efficient and manageable workflow is crucial for any front-end developer. One way to improve your workflow is by utilizing SCSS and Parcel.js. SCSS is a preprocessor scripting language that extends CSS, while Parcel.js is a high-speed web application bundler that requires no configuration. This article will guide you through setting up Parcel.js to compile SCSS into CSS, enhancing your web development process.

Understanding SCSS and Parcel.js

SCSS (Sassy CSS):

  • SCSS is an extension of CSS that allows you to use variables, nested rules, mixins, functions, and more, all within your CSS file.
  • It makes your CSS more maintainable, readable, and reusable.


  • A web application bundler that offers a simplified setup process.
  • Automatically transforms and bundles your assets without the need for extensive configuration.

Setting Up Your Project

1. Install Node.js:
Ensure Node.js is installed on your system. You can download it from Node.js official website.

2. Initialize Your Project:
Create a new directory for your project and initialize it with npm.

mkdir my-project
cd my-project
npm init -y
Enter fullscreen mode Exit fullscreen mode

3. Install Parcel.js:
Install Parcel.js in your project directory.

npm install --save-dev parcel-bundler
Enter fullscreen mode Exit fullscreen mode

4. Project Structure:
Create a basic project structure. For instance:

  • index.html: Your main HTML file.
  • styles/: Directory for SCSS files.
  • styles/main.scss: Your main SCSS file.

5. Link SCSS to HTML:
In your index.html, link to the SCSS file (Parcel will handle the compilation to CSS).

<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My Project</title>
    <link rel="stylesheet" href="./styles/main.scss">
    <h1>Hello, World!</h1>
Enter fullscreen mode Exit fullscreen mode

Writing SCSS

In styles/main.scss, you can start writing your SCSS. For example:

$primary-color: #3498db;

body {
    font-family: 'Arial', sans-serif;
    color: $primary-color;
Enter fullscreen mode Exit fullscreen mode

Running Parcel

1. Add a Start Script:
Modify your package.json to include a start script.

"scripts": {
    "start": "parcel index.html"
Enter fullscreen mode Exit fullscreen mode

2. Run Your Project:
Start your project using npm.

npm start
Enter fullscreen mode Exit fullscreen mode

Parcel will automatically compile your SCSS to CSS and open your project in the browser. Any changes you make in your SCSS file will be instantly compiled and updated in the browser.


Using SCSS with Parcel.js simplifies the development process, making it more efficient and manageable. With automatic compilation and a zero-configuration setup, Parcel.js allows you to focus more on writing code and less on configuring your build tools. This setup is ideal for developers looking to streamline their workflow and enhance their web development experience.
