Gulp task to replace the src attribute of an html script element so the browser doesn't cache it.

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

function cache_version() {
    return (Math.floor((Math.random() * 1000) + 1)).toString(); 
}

gulp.task('version', function () {
    var version = cache_version();
    var regex = /src(\s)?=(\s)?["'][\S]*(\.)js/g;
    gulp.src('src/*.html')
    .pipe(replace(regex, function (found) {
        return found += '?v=' + version;
    }))
    .pipe(gulp.dest('build'));
});
