Full-Stack Web Development with Vue.js and Node

Introducing REST APIs Chapter 4

const route = require("./controllers/" + file)

route.controller(app)

}

})

// catch 404 and forward to error handler

app.use(function(req, res, next) {

var err = new Error('Not Found');

err.status = 404;

next(err);

});

// 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');

});

module.exports = app;

app.listen(3000, function() {

console.log('listening on 3000')

})

Since this file is auto-generated when we build the application via command CLI, it uses

typescript syntax. If we want to use the ES 6 syntax, we can replace var with const.

In our models/User.js, we have the following:

const mongoose = require("mongoose")

const Schema = mongoose.Schema

const UserSchema = new Schema({

name: String,

email: String

})

const User = mongoose.model("User", UserSchema)

module.exports = User
