After creating the directory you will need to change into that directory. For this demo I am creating a directory called node-demo. To get started I would recommend creating a new database that will contain our application. We will be using an API to define when we add data to our database and when we read from the database. Restful APIĪ RESTful API is an application program interface that uses HTTP requests to GET, PUT, POST and DELETE data. In this example you will be providing examples of Creating new data into the database and then Reading the data from the database. It is used to describe the process of having your data persisted into a database.

CRUDĬRUD is an acronym that means Create, Read, Update and Delete. After that we will start building our example. It will also show all items that have been entered into the database.īefore we get started I will describe a few terms that you will frequently hear when creating a MEAN stack application.

We will be creating a very simple Node application, that will allow users to input data that they want to store in a MongoDB database.

In this tutorial I will show you how to use Express.js, Node.js and MongoDB.js. A promise provides two methods that will handle both of these scenarios.The MEAN stack is used to describe development using MongoDB, Express.js, Angular.jS and Node.js. This save will either finish successfully or it will fail. A promise is what is returned when the save to the database completes. Mongoose will return a promise on a save to the database. Once we have it then we just need to enter the command “save”. We will pass into this instance the user’s input. To save the data into the database, we need to create a new instance of our model that we created early. Our body-parser middleware, will convert the user’s input into the JSON format for us. Mongoose provides a save function that will take a JSON object and store it in the database. var express = require("express") var app = express() var port = 3000 app.get("/", (req, res) => )) Saving data to database

In our app.js we are going to add the following code to build a very simple Node.js Application. The first step is to create a file that will contain our code for our Node.js server. Here are the answers I gave to the prompts.

Once we are in the directory we will need to create an application and we can do this by running the command npm init The MEAN stack is used to describe development using MongoDB, Express.js, Angular.jS and Node.js.
