MERN STACK APP TUTORIAL CODE

You can just write HTML, and it lets you insert the same piece of code in multiple locations (called partials) or pass server-side variables to be displayed on the front-end (such as a username). Learning a templating language can be easier than a JS framework. Other popular templating engines include Handlebars, Pug, and Nunjucks.Īfterwards, we will deploy our Node.js web app to DigitalOcean and cover domain names, SSL, reverse proxies, and process managers. But instead of using Angular or React, we will use a templating engine called EJS (Embedded JavaScript.) Our tech stack will be similar to the popular MEAN/MERN stack (MongoDB, Express, Angular or React, and NodeJS).

MERN STACK APP TUTORIAL HOW TO

( You should be in the same folder as the server.This tutorial will show you how to convert a static website that uses HTML, CSS and JavaScript (JS) to a dynamic one using MongoDB, Express, Static HTML, CSS, JS, and Node.js. Let’s test that we can start our server using the following command. These steps are very common for most apps that are built using Express. If you decide to push to a service like Heroku it will use whatever port is in the variable. For now since we are running server.js locally the port will be 5000.

Lastly we set the port and start listening for requests on that port.

Next we use Mongoose to connect to Mongo passing in the uri.

When we connect to Mongo it will create the database once we’ve inserted data. Notice we’ve tacked on what we want to our database name to be.

Then we specify the uri where we can connect to find mongo mongodb://localhost/313-demo-mern-db.

Next, we configure the app to accept json requests.

Then we setup an app through express and assign it to the app variable.

First we require all the libraries that we will be using.

Specify the Port where the backend server can be accessed and start listening on that portĬonst port = process.

MERN STACK APP TUTORIAL INSTALL

We’ll detail what each of these packages do after we show the command to install them.Ĭonst mongoose = require ( "mongoose" ) Ĭonst bodyParser = require ( "body-parser" ) Ĭonst db = ""mongodb : //localhost/313-demo-mern-db"

We’ll be installing body-parser, express, mongoose, and concurrently. Now we’ll install some of the dependencies we’ll be using with npm. "test": "echo "Error: no test specified " & exit 1" Save it as a dependency in the package.json file.Ībout to write to /Users /alexthompson /Google Drive / (OR01 ) Object Rocket - MASTER / 300- 399 / 313-Demo-MERN /package.json: Use `npm install ` afterwards to install a package and See `npm help json ` for definitive documentation on these fields It only covers the most common items, and tries to guess sensible defaults. This utility will walk you through creating a package.json file. We’ll put our new app in a directory called 313-Demo-MERN. Setup a MERN App Locally Part 1 Initializing the Projectįirst you’ll want to create a new directory for your new application. Some command line experience is recommended.Articles about the install process are easy to follow and after it’s installed you can typically start MongoDB with the mongod command which runs the Mongo Daemon. You should have MongoDB installed and running.Node comes with the node package manager (npm) which we’ll also need to install our packages. This is an increasingly common stack and we hope this tutorial can get you started with a simple app that you can build learn from or build into the app you’re envisioning. MongoDB is the database technology, Express is a Javascript framework that assists in easily creating routes, React is the front-end framework, and NodeJS allows you to run JavaScript on your backend server. The MERN stack is composed MongoDB, Express, React, and NodeJS. In this multi-part tutorial we’ll show you how to setup a basic MERN application on your locally.
