I am setting up my server.js file in angular following a tutorial. In the tutorial he has no errors while my fat arrow funtion is saying "expression expected". I am new to javascript and mainly know Java.


var express = require('express');
var bodyParser = require('body-parser');
var path = require('path');
var http = require(http);
var app = express();

var api = require('./server'/api);

app.use(bodyParser.urlencoded({extended: false}));

app.use(express.static(path.join(__dirname, 'dist')));

app.use('/', api);

app.get('*'), (req, res) => {
  res.sendFile(path.join(__dirname, "dist/index.html"));

var port = precess.env.PORT || '3000';
app.set('port', port);

var server = http.createServer(app);
server.listen(port, () => console.log("Server is running"));

You need to remove the bracket here

app.get('*', (req, res) => {
  res.sendFile(path.join(__dirname, "dist/index.html"));

Also you need to reposition your quote mark here to be at the end of the string

var api = require('./server/api');

Also, which version of node are you using, as there is a chance arrow functions are not supported?

I can see you've got a few errors:

var http = require(http); should be var http = require('http');

var api = require('./server'/api); should be var api = require('./server/api');

(both missing ')

var port = precess.env.PORT || '3000'; should be var port = process.env.PORT || '3000'; (typo in process)

and, app.get(... should be

app.get('*', (req, res) => { res.sendFile(path.join(__dirname, "dist/index.html")); })

(the end bracket is in the wrong place)

You have an error on the port property:

var port = precess.env.PORT || '3000';

change it to

var port = process.env.PORT || '3000';

Change the word precess to process.
