from what i can see its starting the angular app and im trying to start express on port 3000

Here is my server.js file

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

app.use("/", api);

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

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

var server = http.createServer(app);

server.listen(port, function(){
    console.log("server running on 3k");

and here is my api.js file

var app = require('express');
var router = app.Router();
var mongocli = require('mongodb').MongoClient;
var objectid = require('mongodb').ObjectID;

const conn = function(closure){
    return mongocli.connect("mongodb://localhost:27017/newdb", (err, db)=>{
            return console.log(err);


let response ={
    message: null,

var sendError = function(err, res){
    response.status = 501;
    response.message = typeof err == "object" ? err.message : err;


router.get("/tutoral", (req,res)=>{
   = mycol ; 


module.exports = router;

i don't know if maybe my folder structure is to blame or just my code is a little of i would appreciate any help i can get with this issue

    ** NG Live Development Server is listening on localhost:4200, open your browser on http://localhost:4200/ **

    It looks like the dev server is running on port 4200. Looking at the code that means you probably have an environment variable set
