gulp-rev-urlhash

Static asset revisioning by create manifest.json, you can get assets uri like xxx.js?v=hs27skvi from manifest.json

It comes from gulp-rev, and this plugin will not change your dist filename, but add url query v=XXXXXXXX in the manifest.json instead.

You can use manifest.json to get files' latest revisioned name.

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

Install

``
$ npm install --save-dev gulp-rev-urlhash
`

Usage

`js
var gulp = require('gulp');
var revUrlhash = require('gulp-rev-urlhash');

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

API

$3

$3

#### 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.

$3

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

$3

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.

$3

`js
var gulp = require('gulp');
var revUrlhash = require('gulp-rev-urlhash');

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(revUrlhash())
.pipe(gulp.dest('build/assets')) // write rev'd assets to build dir
.pipe(revUrlhash.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:

`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 revUrlhash.manifest():

`js
var gulp = require('gulp');
var revUrlhash = require('gulp-rev-urlhash');

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(revUrlhash())
.pipe(gulp.dest('build/assets'))
.pipe(revUrlhash.manifest({
base: 'build/assets',
merge: true // merge with the existing manifest (if one exists)
}))
.pipe(gulp.dest('build/assets'));
});
`

You can optionally call revUrlhash.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:

`js
var gulp = require('gulp');
var revUrlhash = require('gulp-rev-urlhash');
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(revUrlhash())
.pipe(sourcemaps.write('.'))
.pipe(gulp.dest('dist'));
`

Streaming

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-urlhash in your pipeline:

`js
var gulp = require('gulp');
var browserify = require('browserify');
var source = require('vinyl-source-stream');
var buffer = require('gulp-buffer');
var revUrlhash = require('gulp-rev-urlhash');

gulp.task('default', function () {
return browserify('src/index.js')
.bundle({debug: true})
.pipe(source('index.min.js'))
.pipe(buffer())
.pipe(revUrlhash())
.pipe(gulp.dest('dist'))
});
