gulp-rev

Static asset revisioning by appending content hash to filenames unicorn.css → unicorn-098f6bcd.css

Make sure to set the files to never expire for this to have an effect.

Install

$ npm install --save-dev gulp-rev

Usage

var gulp = require('gulp');
var rev = require('gulp-rev');

gulp.task('default', function () {
	return gulp.src('src/*.css')
		.pipe(rev())
		.pipe(gulp.dest('dist'));
});

Options are intentionally missing as the default should work in most cases.

Original path

Original file paths are stored at file.revOrigPath. This could come in handy for things like rewriting references to the assets.

Asset hash

The hash of each rev'd file is stored at file.revHash. You can use this for customizing the file renaming, or for building different manifest formats.

Asset manifest

var gulp = require('gulp');
var rev = require('gulp-rev');

gulp.task('default', function () {
	// by default, gulp would pick `assets/css` as the base,
	// so we need to set it explicitly:
	return gulp.src(['assets/css/*.css', 'assets/js/*.js'], {base: 'assets'})
		.pipe(gulp.dest('build/assets'))  // copy original assets to build dir
		.pipe(rev())
		.pipe(gulp.dest('build/assets'))  // write rev'd assets to build dir
		.pipe(rev.manifest())
		.pipe(gulp.dest('build/assets')); // write manifest to build dir
});

An asset manifest, mapping the original paths to the revisioned paths, will be written to dist/rev-manifest.json:

{
	"css/unicorn.css": "css/unicorn-098f6bcd.css"
}
