Question

I am getting following error
Function.Module._resolveFilename (module.js:547:15) at Function.Module._load (module.js:474:25) at Module.require (module.js:596:17) at require (internal/module.js:11:18) at Object.

PFB source code for your ref.
My server.js file
var express = require("express");
var app = express();
var mongoose = require("mongoose");
var methodOverride = require("method-override");
var port = process.env.PORT || 8080;
var database = require('./config/database');
var morgan = require("morgan");
var bodyParser = require("body-parser");
mongoose.connect('mongodb://localhost:27017', function(err){
if (err){
console.log(err);
}else{
console.log("Connected to DB");
}
});
app.use(express.static(__dirname + '/public'));
app.use(morgan('dev'));
app.use(bodyParser.urlencoded({'extended':'true'}));
app.use(bodyParser.json());
app.use(bodyParser.json({ type : 'application/vnd.api+json'}));
app.use(methodOverride());
require('./models/routes')(app);
app.listen(port);
console.log("App listining to port" + port);
My routes.js file
var Todo = require('./models/todo');
module.exports = function(app){
app.get('/api/todos', function(req, res){
Todo.find(function(err, todos){
if (err)
res.send(err)
res.send(todos)
});
});
// create todo and send back all todos after creation
app.post('/api/todos', function(req, res){
// create a todo, information comes from AJAX request from Angular
Todo.create({
text : req.body.text,
done : false
}, function(err, todo) {
if (err)
res.send(err);
//get and return all the todos after you create another
Todo.find(function(err, todos){
if (err)
res.send(err)
res.json(todos);
});
});
});
//delete a todo
app.delete('/api/todos/:todo_id', function(req, res){
Todo.remove({
_id : req.params.todo_id
}, function(err, todo){
if (err)
res.send(err);
//get and return all the todos after you create another
Todo.find(function(err, todos){
if (err)
res.send(err)
res.json(todos);
});
});
});
// server.js
// application -------------------------------------------------------------
app.get('*', function(req, res) {
res.sendfile('./public/index.html'); // load the single view file (angular will handle the page changes on the front-end)
});
};

The issue is in server.js file. Try with below updated solution
Server.js:
var express = require("express");
var app = express();
var mongoose = require("mongoose");
var methodOverride = require("method-override");
var port = process.env.PORT || 8080;
var database = require('./config/database');
var morgan = require("morgan");
var bodyParser = require("body-parser");
var routes = require('./app/models/routes');
mongoose.connect('mongodb://localhost:27017', function(err){
if (err){
console.log(err);
}else{
console.log("Connected to DB");
}
});
app.use(express.static(__dirname + '/public'));
app.use(morgan('dev'));
app.use(bodyParser.urlencoded({'extended':'true'}));
app.use(bodyParser.json());
app.use(bodyParser.json({ type : 'application/vnd.api+json'}));
app.use(methodOverride());
app.use('/api', routes); // you should add base path like this and assign routes
app.listen(port);
console.log("App listining to port" + port);
And in routes.js file remove /api because we added /api as base path in server.js
var Todo = require('./todo');
module.exports = function(app){
app.get('/todos', function(req, res){
Todo.find(function(err, todos){
if (err)
res.send(err)
res.send(todos)
});
});
// create todo and send back all todos after creation
app.post('/todos', function(req, res){
// create a todo, information comes from AJAX request from Angular
Todo.create({
text : req.body.text,
done : false
}, function(err, todo) {
if (err)
res.send(err);
//get and return all the todos after you create another
Todo.find(function(err, todos){
if (err)
res.send(err)
res.json(todos);
});
});
});
//delete a todo
app.delete('/todos/:todo_id', function(req, res){
Todo.remove({
_id : req.params.todo_id
}, function(err, todo){
if (err)
res.send(err);
//get and return all the todos after you create another
Todo.find(function(err, todos){
if (err)
res.send(err)
res.json(todos);
});
});
});
// server.js
// application -------------------------------------------------------------
app.get('*', function(req, res) {
res.sendfile('./public/index.html'); // load the single view file (angular will handle the page changes on the front-end)
});
};
The schema should be created below way but what you are doing is wrong
var mongoose = require('mongoose');
const Schema = mongoose.Schema;
const BlogPost = new Schema({
text : String,
done : Boolean
});
module.exports = mongoose.model('Todo', BlogPost);

I think you wrote bad path to routes.js file.
Try
require('./app/models/routes')(app);
instead of
require('./models/routes')(app);
