Path issue for Angular 2 app from node js routing

I am trying to serve an Angular 2 app from node js routing. After serving index.html it is giving below errors

localhost:3000/client/src/styles.css 404 (Not Found)

localhost:3000/client/srcsystemjs.config.js 404 (Not Found)

localhost:3000/client/srcsystemjs.config.js 404 (Not Found)

Below are my files and folder structure

1)routes/index.js

router.get('/', function (req, res, next) {
res.sendFile('/angular2/login-module/client/src/index.html');

});

2)index.js

app.use(express.static(__dirname + 'client'));

3)App folder structure

Please someone help. Thanks in advance.
