gulp-rev-dist-clean

gulp-rev-dist-clean is a gulp package to ease clean-up of temporary and legacy files created by the gulp-rev plugin.

How It Works

The plugin parses the rev-manifest.json file created by gulp-rev and compares it to your directory tree, deleting tempory files that you do not wish to keep.

For instance, according to the following rev-manifest.json file:

{
  "css/libs.css": "css/libs-beaeb26c53.css",
  "css/main.css": "css/main-3b7de4f4f1.css",
  "js/libs.js": "js/libs-a90857797b.js",
  "js/main.js": "js/main-beaeb26c53.js"
}

and the following directory tree:

build/assets
├─── css
│    ├─── libs.css
│    ├─── libs-beaeb26c53.css
│    ├─── main.css
│    ├─── main-3b7de4f4f1.css
│    ├─── old-file.css
│    └─── old-file-55900dd045.css
├─── js
│    ├─── libs.js
│    ├─── libs-a90857797b.js
│    ├─── main.js
│    └─── main-beaeb26c53.js
└─── rev-manifest.json

the plugin will always delete the following files, because they are not listed in the manifest:

• build/assets/css/old-file.css
• build/assets/css/old-file-55900dd045.css

It can optionally remove either the revised files (via the keepRenamedFiles option):

• build/assets/css/libs-beaeb26c53.css
• build/assets/css/main-3b7de4f4f1.css
• build/assets/js/libs-a90857797b.js
• build/assets/js/main-beaeb26c53.js

and/or the original files (via the keepOriginalFiles option):

• build/assets/css/libs.css
• build/assets/css/main.css
• build/assets/js/libs.js
• build/assets/js/main.js

and/or the manifest file itself (via the keepManifestFile option):

• build/assets/rev-manifest.json

Prerequisites

You already have a task creating a manifest file via the gulp-rev plugin:

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

gulp.task('default', () =>
    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())
        .pipe(gulp.dest('build/assets'))
);

Installation

First, install the plugin via npm:

npm install --save-dev gulp-rev-dist-clean

Usage

Add the plugin to the imported node modules and create a new task as following. The plugin will clean all the matching directories according to the specified manifest file.

const gulp = require('gulp');
const rev = require('gulp-rev');
const revDistClean = require('gulp-rev-dist-clean');

gulp.task('default', () =>
    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())
        .pipe(gulp.dest('build/assets'))
);

gulp.task('rev-dist-clean', () =>
    gulp.src(['build/assets/**/*'], {read: false})
        .pipe(revDistClean('build/assets/rev-manifest.json'))
);

Notes

• the plugin doesn't need to access the content of your files, hence you can add the read: false optimization in gulp.src()
• the plugin only deletes files (sub-directories are emptied but wont be deleted)

Options

Options can be passed as the second parameter:

gulp.src(['build/assets/**/*'], {read: false})
    .pipe(revDistClean('build/assets/rev-manifest.json', {keepRenamedFiles: false}))

keepOriginalFiles

Type: boolean

Default: true

Keep the original files? [yes/no] (cf. How It Works for an example)

keepRenamedFiles

Type: boolean

Default: true

Keep the revised files generated by gulp-rev's rev() method? [yes/no] (see How It Works for an example)

keepManifestFile

Type: boolean

Default: true

Keep the manifest file generated by gulp-rev's rev.manifest() method? [yes/no] (see How It Works for an example)

emitChunks

Type: boolean

Default: false

Set to true if you need to pipe() the files to another gulp plugin.

When set to false nothing will get emitted to the stream.

forceDelete

Type: boolean

Default: false

Set to true if you want force delete files in your directory. This option remove error

Cannot delete files/folders outside the current working directory. Can be overriden with the `force` option.
