var cache = require('gulp-cache');
var browserSync = require('browser-sync').create();
gulp.task('browser-sync', function() {
    browserSync.init({
        injectChanges: true,
        proxy: "http://localhost:8888/project/source/"
    });
    gulp.watch("source/**/*").on("change", function(e) {
        cache.clearAll();
        return gulp.src(e.path)
            .pipe(browserSync.reload({stream: true}));
    }); 
});
