Fuset

Fuset combines multiple files together and returns them in the web response. Fuset will combine the files once at startup and the content in memory for faster responses.

Installation

This is a Node.js module available through the npm registry. Installation is done using the npm install command:

npm install @kiserit/fuset

Get started

Here's a sample Express app that uses Fuset:

const express = require("express");
const cachet = require('@kiserit/fuset');
const UglifyJS = require("uglify-js");

// optionally minify your code
const uglyMinifier = (content) => {
  const result = UglifyJS.minify(content);
  return result?.code || content;
}

const app = express();

app.get('/sample.js', fuset({
    files: [
      './public/sample1.js',
      './public/sample2.js',
      './public/sample3.js'
    ],
    cache: 'max-age=10800',
    mime: 'javascript/text',
    minifier: uglyMinifier,
  })
)

app.listen(3000);

You can also import fuset from '@kiserit/fuset' if you prefer.

Options

path

A relative or absolute path in which all files in the path will be combined.

files

An array of files to combine. These can be relative or absolute paths.

cache

This is the Cache-Control header to use when returning the file content.

mime

This is the Content-Type header to use when returning the file content. This will be used exactly as specified, but should be the mime type.

minifier

This is a function that takes one string parameter and returns a string. The function will be passed the raw content of the combined files. The result of the function will be used when returning the response content.
