fly-rev

2.3.0 • Public • Published

fly-rev Build status npm package

Prepare front-end assets for cache-busting / versioning / hashing.

This plugin includes three functions:

  1. rev(): Rename files by appending a unique hash, based on contents.
  2. revManifest(): Create a manifest that maps old filenames to newly versioned filenames. (optional)
  3. revReplace(): Update all references to versioned files. (optional)

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

Install

npm install --save-dev fly-rev

Usage

The rev() task is the core method; thus is required for anything to occur.

Both revManifest() and revReplace() are optional plugins.

exports.default = function * (fly) {
  yield fly.source('app/**/*')
    .rev({
      ignores: ['.html', '.jpg', '.png']
     })
    .revManifest({
      dest: 'dist',
      file: 'manifest.json',
      trim: str => str.replace(/app\/client/i, 'assets')
    })
    .revReplace({
      ignores: ['.php']
    })
    .target('dist');
}

API

.rev(options)

Generate a unique hash (based on a file's contents) and append it to the filename.

bundle.js
//=> bundle-{hash}.js
bundle.min.js
//=> bundle-{hash}.min.js

Any files that are processed will receive two new keys: orig and hash. In addition, the base key will be updated with the new, versioned filename.

options.ignores

Type: array
Default: ['.png', 'jpg', '.jpeg', '.svg', '.gif', '.woff', '.ttf', '.eot']

A list of file extensions that should NOT be renamed/processed.

revManifest(options)

Create a manifest file that relates old filenames to versioned counterparts.

options.file

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

The name of the manifest file to be created.

options.dest

Type: string
Default: fly.root

The directory where your manifest file should be created. Defaults to Fly's root directory (where flyfile.js is found).

options.sort

Type: boolean
Default: true

Whether or not the manifest's contents should be sorted alphabetically. (Does not add any performance / usage benefits.)

options.trim

Type: string or function
Default: .

Edit the final keys & values within the manifest. If string, the value will be resolved relative to Fly's root directory. Using a function provides more fine-tuned control.

yield fly.source('app/client/*.js').rev()
  .revManifest({trim: 'app'}).target('dist');
  //=> "client/demo.js": "client/demo-1abd624s.js"
 
yield fly.source('app/client/*.js').rev()
  .revManifest({
    trim: str => str.replace(/app\/client/i, 'assets')
  }).target('dist');
  //=> "assets/demo.js": "assets/demo-1abd624s.js"

revReplace(options)

Update references to all versioned files within a given source.

Matching files from within fly.source() are available for inspection & modifications. Because of this, it is recommended that all your rev-* usage is extracted to a separate, production-only task whose source includes all development files.

options.ignores

Type: array
Default: ['.png', 'jpg', '.jpeg', '.svg', '.gif', '.woff', '.ttf', '.eot']

A list of file extensions whose content should not be updated.
