Static asset revisioning by appending content hash to filenames
unicorn.css→unicorn-d41d8cd98f.css
This project is feature complete.
Make sure to set the files to never expire for this to have an effect.

$ npm install --save-dev gulp-rev
const gulp = require('gulp');
const rev = require('gulp-rev');
gulp.task('default', () =>
gulp.src('src/*.css')
.pipe(rev())
.pipe(gulp.dest('dist'))
);Type: string
Default: rev-manifest.json
Manifest file path.
Type: string
Default: process.cwd()
Override the base of the manifest file.
Type: string
Default: process.cwd()
Override the current working directory of the manifest file.
Type: boolean
Default: false
Merge existing manifest file.
Type: object
Default: JSON
An object with parse and stringify methods. This can be used to provide a
custom transformer instead of the default JSON for the manifest file.
Original file paths are stored at file.revOrigPath. This could come in handy for things like rewriting references to the assets.
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.
const gulp = require('gulp');
const rev = require('gulp-rev');
gulp.task('default', () =>
// by default, gulp would pick `assets/css` as the base,
// so we need to set it explicitly:
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 build/assets/rev-manifest.json:
{
"css/unicorn.css": "css/unicorn-d41d8cd98f.css",
"js/unicorn.js": "js/unicorn-273c2cin3f.js"
}By default, rev-manifest.json will be replaced as a whole. To merge with an existing manifest, pass merge: true and the output destination (as base) to rev.manifest():
const gulp = require('gulp');
const rev = require('gulp-rev');
gulp.task('default', () =>
// by default, gulp would pick `assets/css` as the base,
// so we need to set it explicitly:
gulp.src(['assets/css/*.css', 'assets/js/*.js'], {base: 'assets'})
.pipe(gulp.dest('build/assets'))
.pipe(rev())
.pipe(gulp.dest('build/assets'))
.pipe(rev.manifest({
base: 'build/assets',
merge: true // merge with the existing manifest if one exists
}))
.pipe(gulp.dest('build/assets'))
);You can optionally call rev.manifest('manifest.json') to give it a different path or filename.
Because of the way gulp-concat handles file paths, you may need to set cwd and path manually on your gulp-concat instance to get everything to work correctly:
const gulp = require('gulp');
const rev = require('gulp-rev');
const sourcemaps = require('gulp-sourcemaps');
const concat = require('gulp-concat');
gulp.task('default', () =>
gulp.src('src/*.js')
.pipe(sourcemaps.init())
.pipe(concat({path: 'bundle.js', cwd: ''}))
.pipe(rev())
.pipe(sourcemaps.write('.'))
.pipe(gulp.dest('dist'))
)This plugin does not support streaming. If you have files from a streaming source, such as Browserify, you should use gulp-buffer before gulp-rev in your pipeline:
const gulp = require('gulp');
const browserify = require('browserify');
const source = require('vinyl-source-stream');
const buffer = require('gulp-buffer');
const rev = require('gulp-rev');
gulp.task('default', () =>
browserify('src/index.js')
.bundle({debug: true})
.pipe(source('index.min.js'))
.pipe(buffer())
.pipe(rev())
.pipe(gulp.dest('dist'))
);For more info on how to integrate gulp-rev into your app, have a look at the integration guide.
- gulp-rev-replace - Rewrite occurences of filenames which have been renamed
- gulp-rev-css-url - Override URLs in CSS files with the revved ones
- gulp-rev-outdated - Old static asset revision files filter
- gulp-rev-collector - Static asset revision data collector
- rev-del - Delete old unused assets
- gulp-rev-delete-original - Delete original files after rev
- gulp-rev-loader - Use rev-manifest with webpack
- gulp-rev-format - Provide hash formatting options for static assets (prefix, suffix, last-extension)
