gulp-hash NPM version Build Status

Cachebust your assets by adding a hash to the filename

npm install --save-dev gulp-hash

Basic usage

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


The plugin fully supports both buffers and streams. If you encounter any problems, please open an issue on GitHub and I'll look into it!
