Display Angular 4 in Linux Web Hosting

in my Web Hosting Linux has 512 of RAM and therefore the ng build could not be completed so I resorted to transfer the / dist (locally generated) to the hosting and when I tried to run it with node it does not work.

This is my server.js code

const express = require('express');
const app = express();

app.use(express.static(__dirname + "/dist"));
app.use('/*',function(req, res) {
    res.sendfile(__dirname + '/dist/index.html');
});

app.listen(process.env.PORT || 8080);

and in package.json
