gulp-rev-versionhash

Static asset revisioning by appending content hash to filenames unicorn.cssunicorn.css?v=d41d8cd98f

Install

$ npm install --save-dev gulp-rev-versionhash

Usage

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

API

rev()

rev.manifest([path], [options])

path

Type: string Default: "rev-manifest.json"

Manifest file path.

options

base

Type: string Default: process.cwd()

Override the base of the manifest file.

cwd

Type: string Default: process.cwd()

Override the cwd (current working directory) of the manifest file.

merge

Type: boolean Default: false

Merge existing manifest file.

transformer

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 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-versionhash');
 
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 build/assets/rev-manifest.json:

{
    "css/unicorn.css": "css/unicorn.css?v=d41d8cd98f",
    "js/unicorn.js": "js/unicorn.js?v=273c2cin3f"
}

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():

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

Sourcemaps and gulp-concat

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:

var gulp = require('gulp');
var rev = require('gulp-rev-versionhash');
var sourcemaps = require('gulp-sourcemaps');
var concat = require('gulp-concat');
 
gulp.task('default', function () {
    return gulp.src('src/*.js')
        .pipe(sourcemaps.init())
        .pipe(concat({path: 'bundle.js', cwd: ''}))
        .pipe(rev())
        .pipe(sourcemaps.write('.'))
        .pipe(gulp.dest('dist'));
