An Introduction to API-Centered Application Development with Node.js and MongoDB

Quest 8: Mongoose - Object Data Modeling

Great work getting here! You're a MongoDB with Node.js hero. And Leafie can access and add to his NYC deli database. That's super exciting!

Let's take our API even further. With the basic knowledge of routes and how to connect to MongoDB in Node.js, we'll look a bit at setting up an application following the Model-View-Controller (MVC) design pattern. Well, we don't have much a view necessarily, but let's tackle models and controllers. Let's start a new project in a mongoose_app directory.

Recall that starting a new Node.js project can be done with:

npm init

We can copy the dependencies from the package.json in our original project into this one to save some time. Another extremely common tool when working with a Node.js, Express, and MongoDB project is to use the Mongoose ORM package.

npm install --save mongoose

Let's start with our model inside a models subfolder. Mongoose allows us to define a schema to follow.

const mongoose = require('mongoose');

const deliSchema = mongoose.Schema({
    name: String,
    rest_id: Number,
    street: String,
    district: String,
    city: String,
    state: String,
    postal_code: Number,
    specialty: String

}, {collection: 'delis'});

module.exports = mongoose.model('Deli', deliSchema);
