Connecting to MongoDB in MEAN Stack

Library and data model

Data model specifies what data is present in a document, and what data should be there in a document. For this we’ll be using Mongoose — a data modelling library that specifies environment and structure for the data. You can install Mongoose as a npm module through the command line.

npm install — save mongoose

Alright, since I started to get more serious with my garden project — so I chose to centralise our MEAN exercise around vegetables 🥦🥒

Setting connection file — app/models/vegetables

var mongoose = require(‘mongoose’);
module.exports = mongoose.model(‘Vegetable’, { name : {type : String, default: ‘’} });

Create database connection configuration — config/db.js

module.exports = { url : ‘mongodb://localhost:27017/test’ }

Launch Robo 3t and create new database name “test”, new collection name “vegetables” :

Insert some data to this collection. Let’s pick Kale for now.

Project Structure

Run command to restart the server

npm start

You may use your favourite API testing tool (Postman, Insomnia etc) to access the same route.
