gulp-hash

gulp-hash

Cachebust your assets by adding a hash to the filename

npm install --save-dev gulp-hash

Basic usage

var hash = require('gulp-hash');

gulp.src('./js/**/*.js')
	.pipe(hash()) // Add hashes to the files' names
	.pipe(gulp.dest('public/js')) // Write the renamed files
	.pipe(hash.manifest('assets.json')) // Switch to the manifest file
	.pipe(gulp.dest('public')); // Write the manifest file

The "manifest" is a JSON file that maps the original filenames to the renamed ones.

Streaming

The plugin has full streaming support. If you encounter any problems, please open an issue on GitHub and I'll look into it!
