Node js form submit leads to following error - Error: Cannot POST / [duplicate]

This question already has an answer here:
Node js form submit TypeError: Cannot set property 'userId' of undefined

Closed 2 years ago.
I have added login/registration features to my application. These added features, when used in a separate folder work perfectly, as well as my application on its own. However, adding the login/registration features to my perfectly working application has led me to this error. This would happen when I would type in my details on the login page and click the register button (registering an account) to receive the following message on my browser tab 'Error: Cannot POST /' . I cannot understand why I am getting this error. Here is the code I am working with right now that gets me this errorr. I am new to node js etc so I apologise if this is simple! I am using MongoDB Compass Community as my database. Also, apologies for a lot of code but this is all the code necessary to use my login/registration features.

You are missing the first slash in the route post 'employee/login'
You just have to change this line:
router.post('employee/login', function (req, res, next) {
To be like that:
router.post('/employee/login', function (req, res, next) {
this should fix the route.
In your form you must change the action property to point to the route that handles the post request.
<form action="/employee/login" method="post">
That should fix.

Angular app hangs when POST request is given, Chrome console gives error ERR_EMPTY_RESPONSE?

So I am a newbie in MEAN world. I am referring to this book Write Modern Web Apps With The Mean Stack Mongodb Express Angularjs and Node.js. So in this book, they teach us how to build a Twitter close using the MEAN stack. I have just copied the code from the book but it is not working. Can you help me out?

ExpressJs - Finding records matching route parameter

I have been building out a tagging system for my ExpressJS application and I have been able to create my routing to pick up on the individual tags that are used for my record, but the issue I am running into is trying to display content associated with the selected tag. For instance a record has a tag "Mouse", when clicked the route correctly goes to /tag/mouse, but I'm not sure if I should use a loop within my template to display only those values or if I should really be using a method within my route. I'm currently using nothing and the value being displayed on the tag page is undefined. I have a feeling the route method is what I am looking for.
Here is the main focus of my routes file:
var express = require('express');
var router = express.Router();
var passport = require('passport');
var blogDB = require('../config/blogDB.js');
var Blogpost = require('./models/blogModel.js');
var paginate = require('express-paginate');
var http = require('http');
var path = require('path');
var aws = require('aws-sdk');

blogpost.title = req.body.title; // set the blog title
blogpost.featureImage = req.body.featureImage; // set the blog image
blogpost.blogUrl = blogpost.title.toLowerCase().replace(/\s+/g,"-");
blogpost.author = req.body.author; // set the author name
blogpost.tagline = req.body.tagline; // set the tagline
blogpost.content = req.body.content; // set the blog content
blogpost.category = req.body.category; // set the category
blogpost.tags = req.body.tags.trim().split(","); // set the tags
//Save Blog Post
blogpost.save(function(err) {
if (err)
res.send(err);
res.redirect(303, '/'); //NEEDS TO BE CHANGED
});
}) // END POST method
.get(isLoggedIn, function(req, res, blogpost) {
res.render('pages/blogpost-create', {

ExpressJS Link to Update Content

I am trying to be able to update my content via my editor, but I'm wondering what part of my application I should be modifying to be able to do this. I have a feeling that it is through the route file, but was wondering if there was a hyperlink method that I should be using from within my view to be able to generate my view with the content I want to edit.

Not being able to POST in MEAN single page app

I have only just started trying out NodeJS. Having a little experience with Angular, I thought of trying out a MEAN stack to-do app tutorial from scotch.
I understand what is happening and how angular, node and my view are supposed to be working together. But they just aren't. I've made sure not to miss anything. Here is my code.
Server.js is in the root folder
// server.js
// set up ========================
var express = require('express');
var app = express(); // create our app w/ express
var mongoose = require('mongoose'); // mongoose for mongodb
var mongodb = require('mongodb');
var morgan = require('morgan'); // log requests to the console (express4)
var bodyParser = require('body-parser'); // pull information from HTML POST (express4)
var methodOverride = require('method-override'); // simulate DELETE and PUT (express4)
// configuration =================
mongoose.connect('mongodb://<user>:<pass>#proximus.modulusmongo.net:27017/uwa8sIje'); // connect to mongoDB database on modulus.io
app.use(express.static(__dirname +'/public')); // set the static files location /public/img will be /img for users
app.use(morgan('dev')); // log every request to the console

My angular controller lies in the public folder along with my view
var Todoz = angular.module('Todoz', []);
function mainController($http, $scope) {
$scope.formData = {};
$http.get('/api/todos')
.success(function (data) {
$scope.todos = data;
console.log(data);
})
$scope.createTodo = function() {
$http.post('/api/todos', $scope.formData)
.success(function (data) {
$scope.formData = {};
$scope.todos = data;
})
.error(function (data) {
console.log('Error' + data)
})
}
$scope.deleteTodo = function(id) {
$http.delete('/api/todos/' + id)
.success(function (data) {
$scope.todos = data;
console.log(data);
})
.error(function (data) {
console.log(data)
});
};
Todoz.controller("mainController", mainController);
}
and my minimal view
<head>
<title>
To-Do-and-Node-To-Do
</title>
</head>
<body ng-app="Todoz">
<h1>The To-do-ist</h1>
<div ng-controller="mainController">

When I start the server with 'nodemon server.js' my console logs a /GET request and the app shows on my port 8080. However when I try to post a new item from my text-box and expect it to console.log, it doesn't do anything. My browser console returns this
POST http://localhost:8080/api/todos net::ERR_CONNECTION_REFUSED angular.js:8632
Error core.js:23
POST http://localhost:8080/api/todos net::ERR_CONNECTION_REFUSED angular.js:8632
Error core.js:23
Please help. I have no clue what is going wrong.
