Create a JSON map of file hashes, passing all files through.
var hash = require("gulp-hashmap"),
uglify = require("gulp-uglify");
// Uglify scripts, create a hashmap and write all to the dist directory
grunt.task("build", function() {
grunt.src("scripts/*.js")
.pipe(uglify())
.pipe(hash("hashmap.json"))
.pipe(grunt.dest("dist/"));
});MIT
