gulp-dom-src

Create a gulp stream from script, link, or any set of tags in an HTML file.

Example

var gulp = require('gulp');
var domSrc = require('gulp-dom-src');
var concat = require('gulp-concat');
var uglify = require('gulp-uglify');

gulp.task('default', function () {
	domSrc({ file: 'index.html', selector: 'script', attribute: 'src' })
        .pipe(concat('app.full.min.js'))
        .pipe(uglify())
        .pipe(gulp.dest('dist/'));
});

API

domSrc(config)

config.file

Type: String

The name of the HTML file to read the tags from.

config.selector

Type: String

Any valid CSS selector. You can use complex selectors to allow flexible include/exclude logic for your tags. For example, use a selector such as script[data-concat!="false"] and put data-concat="false" on any script tags you wish to exclude from a concat/minification stream.

config.attribute

Type: String

The name of the attribute that contains the file path. Typically src for script tags and href for links.

config.cwd

Type: String (Optional)

The directory where the paths in your tags are relative to. By default, the files references in your script or link tags are assumed to be relative to the HTML file they're read from.

config.options

Type: Object (Optional) Default: {}

Options passed through to the underlying vinyl-fs. Can include options like read and buffer.

domSrc.duplex(config)

Creates a stream that html files can be piped into -- html files in, script or style files out.

config.selector, config.attribute, config.cwd

End-to-End Concatenation and Minification

Combine gulp-dom-src with gulp-cheerio for a full concat & min workflow.

var gulp = require('gulp');
var domSrc = require('gulp-dom-src');
var concat = require('gulp-concat');
var cssmin = require('gulp-cssmin');
var uglify = require('gulp-uglify');
var cheerio = require('gulp-cheerio');

gulp.task('css', function() {
    return domSrc({file:'index.html',selector:'link',attribute:'href'})
    	.pipe(concat('app.full.min.css'))
        .pipe(cssmin())
        .pipe(gulp.dest('dist/'));
});

gulp.task('js', function() {
    return domSrc({file:'index.html',selector:'script',attribute:'src'})
        .pipe(concat('app.full.min.js'))
        .pipe(uglify())
        .pipe(gulp.dest('dist/'));
});

gulp.task('indexHtml', function() {
    return gulp.src('index.html')
        .pipe(cheerio(function ($) {
            $('script').remove();
            $('link').remove();
            $('body').append('<script src="app.full.min.js"></script>');
            $('head').append('<link rel="stylesheet" href="app.full.min.css">');
        }))
        .pipe(gulp.dest('dist/'));
});
