Express Server continuously throws 404 error - node.js

Question

I keep getting these errors.
Here's some of my code.
bin/www
#!/usr/bin/env node
/**
* Module dependencies.
*/
var app = require('../app');
var debug = require('debug')('server:server');
var http = require('http');
/**
* Get port from environment and store in Express.
*/
var port = normalizePort(process.env.PORT || '3000');
app.set('port', port);
/**
* Create HTTP server.
*/
var server = http.createServer(app);
/**
* Listen on provided port, on all network interfaces.
*/
server.listen(port);
server.on('error', onError);
server.on('listening', onListening);
/**
* Normalize a port into a number, string, or false.
*/
function normalizePort(val) {
var port = parseInt(val, 10);
if (isNaN(port)) {
// named pipe
return val;
}
if (port >= 0) {
// port number
return port;
}
return false;
}
/**
* Event listener for HTTP server "error" event.
*/
function onError(error) {
if (error.syscall !== 'listen') {
throw error;
}
var bind = typeof port === 'string'
? 'Pipe ' + port
: 'Port ' + port;
// handle specific listen errors with friendly messages
switch (error.code) {
case 'EACCES':
console.error(bind + ' requires elevated privileges');
process.exit(1);
break;
case 'EADDRINUSE':
console.error(bind + ' is already in use');
process.exit(1);
break;
default:
throw error;
}
}
/**
* Event listener for HTTP server "listening" event.
*/
function onListening() {
var addr = server.address();
var bind = typeof addr === 'string'
? 'pipe ' + addr
: 'port ' + addr.port;
debug('Listening on ' + bind);
}

Any suggestions on what I am doing wrong. It's a project that I started a couple of months ago and of course, didn't finish it. I just recently came back to it and can't seem to figure out why my server won't work. Seems to connect fine with the database.

Answer 1

As I can see, your typing '/' url, but in your code there is no '/' route.
Can you add the 'home' route as following, and check again please ?
app.use('/dashboard', eventsRouter);
app.use('/user', usersRouter);
// catch 404 and forward to error handler
// app.use(function(req, res, next) {
// next(createError(404));
// });
app.get('/', (req, res) => {
res.send('home');
});
// error handler
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
res.status(err.status || 500);
res.render('error');
});

#RickyMed have you defined any middleware for / route. Generally 404 Not Found came when url is not present. If not create one or try http://localhost:3000/user.
Check if this is working
