NodeJs in Typescript

I would like to use this way when I'm writing app.ts file. There are some issues concerning .d.ts imports, I don't get full api exposed of express. The issue is that I don't get full autocompletion in Webstorm2016 (haven't tried it vscode - not relevant for me for now).

///<reference path="../../typings/main.d.ts"/>
import * as express from 'express';
import * as logger  from 'morgan';
import * as bodyParser from 'body-parser';
import {join} from 'path';

/* local imports*/
import * as env from '../../tools/tasks';


class Startup {
    private _app: express.Express;
    private _port: number;

    constructor() {
        this._app  = express();
        this._port = env.settings.PORT;

        this.initialize();
        this.setupViews();
        this.listener();
    }

    private initialize() : void {
        // this._app.[use] => not recognized
        this._app.use(logger('dev')); 
        this._app.use(express.static(join(__dirname, 'public')));
        this._app.use(bodyParser.json());
        this._app.use('/', this.router());
    }

    private setupViews() : void {
        // this._app.[engine] => not recognized
        // this._app.[set]    => not recognized
        this._app.engine('.html', require('ejs').__express);
        this._app.set("views", join(__dirname, "views"));
        this._app.set("view engine", "html");
    }

    private router(): express.Router {
        /* routes */
        let index: express.Router = this._app.get('/', (request: express.Request, response: express.Response) => {
            response.render('index', { title: 'This is express initial' });
        });
        return index;
    }

    private listener() : void {
        let server: any =  this._app.listen(this._port, () => {
            var listeningPort: number = server.address().port;
            console.log('The server is listening on port: ' + listeningPort);
        });
    }
}

declare var app = new Startup();

This is my compilation error list:

typings.json:

        {
          "ambientDependencies": {
             "body-parser": "registry:dt/body-    parser#0.0.0+20160317120654",

      }
    }

Actually have found an answer for that issue. For some reason typings stripping the two definitions of:

 - express-serve-static-core/express-serve-static-core.d.ts"
 - serve-static.d.ts

if you install both of them it's starting showing autocompletion.
