Bundle Single Static .mjs File without Any Modules using Vite: A Step-by-Step Guide

Are you tired of dealing with complex bundle configurations and numerous dependencies in your JavaScript projects? Do you want to simplify your development process and focus on writing clean, modular code? Look no further! In this article, we’ll explore how to bundle a single static .mjs file without any modules using Vite, a powerful and lightweight development server.

What is Vite?

Vite is a modern development server that provides a fast and efficient way to build and serve JavaScript applications. It’s designed to work seamlessly with modern JavaScript frameworks and libraries, making it an ideal choice for building fast and scalable applications. Vite’s core features include:

• Lightning-fast development server with Hot Module Replacement (HMR)
• Out-of-the-box support for modern JavaScript features, including ES6 syntax and TypeScript
• Zero-config setup for many popular frameworks and libraries, including React, Vue, and Svelte
• Native support for modern JavaScript features, including Import Maps and Native ESM

Why Bundle a Single Static .mjs File?

Bundling a single static .mjs file without any modules can be beneficial in several scenarios:

• **Simplified Development Process**: By bundling a single file, you can focus on writing clean, modular code without worrying about complex bundle configurations or dependencies.
• **Improved Performance**: A single, optimized bundle file can reduce the number of HTTP requests, improving page load times and overall application performance.
• **Easy Deployment**: A single bundle file is easier to deploy and manage, especially in scenarios where you need to upload files to a CDN or server.

Step-by-Step Guide to Bundling a Single Static .mjs File using Vite

To get started, make sure you have Node.js and npm installed on your system. Then, follow these steps:

Step 1: Create a New Project Directory and Initialize a New npm Project

mkdir vite-bundle-example
cd vite-bundle-example
npm init -y

Step 2: Install Vite as a Development Dependency

npm install --save-dev vite

Step 3: Create a New .mjs File

Create a new file called `main.mjs` in the project root directory:

touch main.mjs

Step 4: Write Your JavaScript Code

In the `main.mjs` file, add the following code:

// main.mjs
console.log('Hello, World!');

Step 5: Create a `vite.config.js` File

Create a new file called `vite.config.js` in the project root directory:

touch vite.config.js

Step 6: Configure Vite to Bundle a Single Static .mjs File

In the `vite.config.js` file, add the following configuration:

// vite.config.js
import { defineConfig } from 'vite';

export default defineConfig({
  build: {
    lib: {
      entry: 'main.mjs',
      name: 'main',
      fileName: 'main',
    },
  },
});

In this configuration, we’re telling Vite to:

• Use the `main.mjs` file as the entry point
• Output a single file named `main.js` in the `dist` directory

Step 7: Run Vite and Bundle the File

Run the following command to start Vite and bundle the file:

npx vite build

Vite will create a new `dist` directory and generate a single, optimized bundle file called `main.js`.

Inspecting the Bundle File

Let’s take a closer look at the generated bundle file:

Bundle File Contents

// dist/main.js
console.log('Hello, World!');

As expected, the bundle file contains the original code from the `main.mjs` file.

Bundle File Size and Optimization

The generated bundle file is highly optimized, with a minimal file size:

// File size: 34 bytes

Vite has automatically removed any unnecessary code and optimized the file for production use.

Conclusion

Bundling a single static .mjs file without any modules using Vite is a straightforward process that requires minimal configuration. By following these steps, you can simplify your development process, improve performance, and deploy a single, optimized bundle file. With Vite, you can focus on writing clean, modular code and let the development server handle the rest.
