Orchestrates JS and CSS bundle creation in an efficient and configurable manner.

## Install

```bash
npm i -D @userfrosting/gulp-bundle-assets
```

## Usage

```js
// gulpfile.mjs
import { BundleOrchestrator } from "@userfrosting/gulp-bundle-assets";
import Gulp from "gulp";
import cleanCss from "gulp-clean-css";
import concatCss from "gulp-concat-css";
import uglify from "gulp-uglify";
import concatJs from "gulp-concat-js";

export function bundle() {
const config = {
bundle: {
example: {
scripts: [
"foo.js",
"bar.js"
],
styles: [
"foo.css",
"bar.css"
]
}
}
};
const joiner = {
Scripts(bundleStream, name) {
return bundleStream
.pipe(concatJs(name + ".js"))// example.js
.pipe(uglify());
},
Styles(bundleStream, name) {
return bundleStream
.pipe(concatCss(name + ".css"))// example.css
.pipe(cleanCss());
}
};

return Gulp.src("src/**")
.pipe(new BundleOrchestrator(config, joiner))
.pipe(Gulp.dest("public/assets/"));
}
```

```bash
$ gulp bundle
```

### CJS Interoperability

This is an ES module package targeting NodeJS `>=22.0.0`, it can be used in CJS contexts via dynamic `import`. Note that ESM loaders like `@babel/loader` or `esm` likely won't work as expected.

```js
// gulpfile.cjs

// ...

module.exports.bundle = async function bundle() {
const { BundleOrchestrator } = await import("@userfrosting/gulp-bundle-assets");

// ...
}
```

## Integrating bundles into your app

A results callback can be provided as a third parameter. On completion, it will be provided with a mapping for bundles to their respective virtual file paths. Note that path transformations performed after the bundler (including `dest`) won't be reflected and should be accounted for.

The "DIY" approach to bundle resulting mapping is used to permit deeper integration with any system, such as generating a file in the target language to decrease integration cost.

## API

See [docs/api](./docs/api/index.md).

## Origins

This plugin was originally forked from [gulp-bundle-assets](https://github.com/dowjones/gulp-bundle-assets) to fix a CSS import bug. It has since undergone numerous refactors to improve performance and flexibility.
