        if( ! error ) bs( options.bs );
    });
});

// If server side's coffee files change, compile these files,
// restart the server and then browser-reload.
gulp.task( 'server:restart', function() {
    gulp.src( serverCoffee )
        .pipe( coffee() )
        .pipe( gulp.dest( './apps' ) )
        .pipe( server() )
        .pipe( bs.reload({ stream: true }) );
