Hi I am getting an error and it is stumping me. I think its on line 33 in “server.js.” Here is all the things that were contributed in the coding.
Server.js
require('dotenv').config();
const express = require('express');
const bodyParser = require("body-parser");
const mongoose = require("mongoose");
const cors = require('cors');
const dns = require('dns');
const urlparser = require('url');
const app = express();
// Basic Configuration
const port = process.env.PORT || 3000;
mongoose.connect(process.env.DB_URI, { useNewUrlParser: true, useUnifiedTopology: true });
console.log(mongoose.connection.readyState)
const schema = new mongoose.Schema({url: 'string'});
const Url = mongoose.model('Url', schema);
app.use(bodyParser.urlencoded({extended: false}))
app.use(cors());
app.use('/public', express.static('${process.cwd()}/public'));
app.get('/', function(req, res) {
res.sendFile(process.cwd() + '/views/index.html');
});
// Your first API endpoint
app.post('/api/shorturl/new', function(req, res) {
console.log(req.body);
const bodyurl = req.body.url;
const something = dns.lookup(urlparser.parse(bodyurl).hostname, (error, address) => {
if (!address) => {
res.json({ error: "Invalid URL"})
} else {
const url = new Url({ url: bodyurl })
url.save((err, data) => {
res.json({
original_url: data.url,
short_url: data.id
})
}
)
}
console.log("dns", error);
console.log("address", address);
})
console.log("something", something);
});
app.get("/api/shorturl/:id", (req, res) => {
const id = req.params.id;
Url.findById(id, (err, data) => {
if(!data){
res.json({error: "Invalid URL"})
}else{
res.redirect(data.url)
}
})
})
app.listen(port, function() {
console.log('Listening on port ${port}');
});
.env
PORT=5000
