Why Angular 2 doesn't load default app-root component? - node.js

Question

I'm trying to start Angular app generated via angular CLI, but it seems like the default app-root component doesn't load. Need to say, that I'm using proxy for connection between angular app and express server, and I'm running two scripts at the same time: node bin/www for express/node.js start and ng serve --proxy-config proxy.config.json for starting Angular and creating proxy connection, it looks like this (the part of package.json):
"scripts": {
"start": "concurrently --kill-others \"node bin/www\" \"ng serve --proxy-config proxy.config.json\""
}
The index page loads fine, but it seems that app-root component (the default component, which was created from angular CLI ng new) doesn't loading:
Here is my node.js/express uses and a route:
var express = require('express');
var router = express.Router();
var app = express();
var path = require('path');
app.use(express.static('./src/client/'));
app.use(express.static('./'));
app.use(express.static('./tmp'));
app.use('/*', express.static(path.resolve('src/client/index.html')));
router.get('*', function(req, res) {
res.sendFile(path.resolve('src/client/index.html'));
});
module.exports = router;
And the structure of my project (if needed):
What did I miss? Why the default app-root component doesn't loading? (need to say, when I run ng serve, it starts the angular homepage as needed and the component is OK, so I think the problem is somewhere in express).
Thanks in advance

You should serve the contents of the dist/ folder after calling ng build --prod (the --prod is important, as the default is --dev). So, it would be something like this:
"scripts": {
"start": "ng build --prod && node bin/www"
}
And, more or less adapting your express script:
app.use(express.static('./dist'));
app.use('/*', express.static(path.resolve('dist/index.html')));
router.get('*', function(req, res) {
res.sendFile(path.resolve('dist/index.html'));
});
