gulp-file-bundle

A Gulp plugin for bundling js and css resources as an external reference.

Overview

The plugin is minimalistic and simple. It generates the bundle file on the fly and adds it to the stream of files passing through it.

For example, the following folder structure:

+ src
    - file1.js
    + fldr
        - file1.js
        - file2.js

And gulp task:

gulp.task('bundle.js', function() {
    return gulp.src('src/**/*.js')
        .pipe(bundle('bundle.js', {
            type: 'js', //can be ommited, it is the default
            base: 'src'
        }))
        .pipe(gulp.dest('dst'));
});

Results in a directory like so:

+ dst
    - bundle.js
    - file1.js
    + fldr
        - file1.js
        - file2.js

And a bundle.js content like so:

document.write('<script src="file1.js"></script>');
document.write('<script src="fldr/file1.js"></script>');
document.write('<script src="fldr/file2.js"></script>');

A css bundling task is similar and looks like this:

gulp.task('bundle.css', function() {
    return gulp.src('src/**/*.css')
        .pipe(bundle('bundle.css', {
            type: 'css',
            base: 'src'
        }))
        .pipe(gulp.dest('dst'));
});

The content of the bundle.css is the following:

@import url(file1.css);
@import url(fldr/file1.css);
@import url(fldr/file2.css);

Parameters

bundle(bundleName, options)

bundleName

Type: String

The name of the bundle file. This file is added to the stream of files passing through the plugin. It is a gulp only file, and must be saved using gulp.dest or a similar facility to be available in the file system.

options

options.emitInputFiles

Type: Boolean Default value: true

By default, the plugin emits all input files before it emits the bundle file, so it add one file to the stream of files. Setting this option to false, will cause the plugin to filter out all input files and only emit the bundle file.

options.type

Type: String Default value: 'js'

Either 'js' or 'css'. Determine the type of the bundle file i.e wether it uses <script src=""> or <link rel=""> tag to reference the external files.

options.base

Type: String

The base to use for the bundle file and the input file. Determines the relative path used for the href and src attributes.
