Build your library for any JavaScript environment without the complexity

Getting Started

SmartBundle makes it easy to bundle your library for any JavaScript environment. Just create a minimal package.json (see below), install SmartBundle, and run the build command.

{
  // Your package name
  "name": "my-package",         
  // Package version
  "version": "1.0.0",           
  // Must be true to avoid accidental publishing
  "private": true,              
  // SmartBundle supports only ES modules
  "type": "module",             
  // Entry point used by SmartBundle
  "exports": "./src/index.js",  
  "scripts": {
    // Run this to build your package
    "build": "smartbundle"      
  }
}

Need more details? See our package.json guide for a full explanation of each field. If you plan to use TypeScript, check out our TS guide for tailored advice.

To build your package:

1) Create the package.json as shown above 2) Install SmartBundle:

npm install --save-dev smartbundle@latest

3) Build your package:

npm run build

4) Your built files (including an auto-generated package.json) will be in the ./dist folder

We aim to support as many bundlers and runtimes as possible. If the bundled package doesn't work with your bundler, please let us know.

Tool Integration

SmartBundle automatically detects and integrates with your tools - just add what you need to your project.

TypeScript

Add typescript@^5.0.0 as a dev dependency and start creating .ts files. SmartBundle will handle the rest.

Babel

Add @babel/core@^7.0.0 as a dev dependency and create a Babel configuration file in your project root. SmartBundle will automatically apply your transformations.

React

Add react to your dependencies. SmartBundle automatically detects React and configures JSX transformations. Both modern and legacy modes are supported.

For detailed React configuration options, see our React guide.

Advanced Usage

SmartBundle enforces certain package.json conventions to ensure reliable builds. For detailed information about: - Required and banned fields - Configuration limitations - Package.json best practices

See our package.json guide.

FAQ

SmartBundle have an issue

Please, look at the known fixable issues before creating your own one. Some bugs already have a solution but cannot be fixed without user action.

Why don't you minify the output?

Minification is typically needed only for production. During development, readable, unminified output helps with debugging.

Why do you require third-party tools for building?

We prioritize keeping the node_modules size manageable and avoid unnecessary dependencies. If your package does not require TypeScript, for instance, you don’t need to install those specific tools.
