We now use the userSchema object to add a virtual password field.

This helps us perform additional validation to ensure that our users are not submitting any random data to our database without us having to write tons of boilerplate code ourselves. However, Mongoose adds a layer of structure on top of the typical MongoDB way of doing things. Typically, NoSQL databases are super flexible, in that they allow us to put whatever we want in them without enforcing any specific kind of structure. We will start by importing the necessary dependencies at the top of our file and then create a new Mongoose Schema, userSchema which is an object with properties. Create a new file inside server/models/user.js. We are going to save user credentials and validate it using Mongoose in this section. To demonstrate, I am going to create a user data model with properties to save the user data when a new user registers with our application. If you are getting a message like below ( ignore the mongoose warning), this means our server is up and running and successfully connected to the local instance of the database. Let’s create a small server in the index.js file of the root of our web app. The most basic benefit is to make a connection between the Express app when it bootstraps and the MongoDB instance on our local machine. It also provides a schema-based solution to create data models and define them in our Node app.Īlthough MongoDB is a schema-less database, Mongoose helps our application understand the data structure and organize it at the same time. This helps write queries inside the Node server and create business logic behind it. I am going to use Mongoose as ODM ( Object Document Mapper).

Let us start by defining the MongoDB connection. Inside config directory, create a new file called dbConnection.js. Make sure add the dev script inside package.json. If you want to use a cloud service (free tier), please read the steps to set it up and consume in a Node server app here. Inside server, create a new file config/index.js and define the following inside it.įor MongoDB, I am going to use a local instance. The next step is to define the configuration you will need to proceed with server creation. To setup and learn what Babel is, please read here. We are going to bootstrap the server using Babel. To keep you from getting lost, I will leave a comment before each command using #.Īfter this step, make sure your root project looks like below with some extra files and folders. To get started, you need to follow the steps below by opening your terminal and typing these commands. The last in the above list are installed using npm.

Pre-requisitesīefore we get started, install all the tools we are going to need to set up our application. You can then use what you learn here for to make your own applications look better and be more functional.

MERN STACK APP TUTORIAL HOW TO

Along with building a simple web app, you will learn how to use the Material UI library to make the application look good. In this tutorial, I am going to show you how to build a small web application using this technology stack, step-by-step. Express is a Nodejs framework that helps you to build a server that communicates to and fro with a NoSQL database like MongoDB. React is the library you will use to build the front-end of the web application. Each of these technologies can be replaced with something comparable but it is common practice to use them together. MERN is full-stack because it consists of MongDB, Express, React and Nodejs. For some developers, UI can be the tricky part. One you have the data user will interact with, you need to focus on developing a functional User Interface ( UI) for your web application. Setting up the the back end and connecting it with a client-side library like React to fetch and display data is just the beginning. It can sometime be overwhelming to build a full-stack web application using a stack like MERN. Learn to build an authenticated full-stack application using MERN, styled with Material UI components.
