hashdirectory

Create an sha1 hash sum from a directory of files using the git algorithm.

Creating a hash for an entire directory, instead of for a single file, can be useful for cache busting. Using git's method of creating the hash just builds upon something consistent that is known to work.

This package does not requires git to be installed on the production server, however. It only reproduces the git algorithm for hashing files and folders (but not commits or tags).

Installation

npm install --save hashdirectory

Usage

var hashdirectory = require('hashdirectory');

// Synchronous, for before your webserver starts up.
var hashed = hashdirectory.sync('./public');

// Asynchronous, for everything else.
hashdirectory('./public', function(err, hashed) {
});

// Or, if promises are more your thing.
var hashedPromise = hashdirectory('./public');
