MEAN stack is a popular web development stack that includes MongoDB, Express, Angular, and Node.js. In this blog, we will show you how to install the MEAN stack on Ubuntu 20 Server.
Step 1: Update Ubuntu 20.04
Before we start, it’s always a good idea to update your Ubuntu server to the latest version. To do this, run the following commands:
sudo apt update
sudo apt upgrade
Step 2: Install Node.js and NPM
Node.js is a JavaScript runtime built on Chrome’s V8 JavaScript engine. To install Node.js and NPM, run the following command:
sudo apt install nodejs npm
Step 3: Install MongoDB
MongoDB is a popular NoSQL database that is used by many web applications. To install MongoDB, run the following commands:
sudo apt update
sudo apt install mongodb
After installation, start the MongoDB service and enable it to start on boot:
sudo systemctl start mongod
sudo systemctl enable mongod
Step 4: Install Angular CLI
Angular is a popular front-end JavaScript framework for building web applications. To install the Angular CLI, run the following command:
sudo npm install -g @angular/cli
Step 5: Install Express
Express is a popular web application framework for Node.js. To install Express, run the following command:
sudo npm install -g express
Step 6: Create a New MEAN Stack Application
Now that you have installed all the necessary components, you can create a new MEAN stack application. To do this, follow these steps:
Create a new directory for your application:
mkdir mean-app
cd mean-app
Initialize your application with NPM:
npm init -y
Install the necessary packages for your application:
npm install express mongodb mongoose body-parser cors
Create a new file called server.js and add the following code:
const express = require(‘express’);
const bodyParser = require(‘body-parser’);
const cors = require(‘cors’);
const mongoose = require(‘mongoose’);const app = express();
// Middleware
app.use(bodyParser.json());
app.use(cors());// Connect to MongoDB
mongoose.connect(‘mongodb://localhost:27017/mean-app’, { useNewUrlParser: true });const connection = mongoose.connection;
connection.once(‘open’, () => {
console.log(‘MongoDB database connection established successfully!’);
});// Start the server
const port = process.env.PORT || 4000;
app.listen(port, () => {
console.log(`Server running on port ${port}`);
});
Start the server:node server.js.
Open your web browser and navigate to http://localhost:4000. You should see a message indicating that the server is running.
Conclusion
In this blog, we have shown you how to install the MEAN stack on Ubuntu 20.04 . By following these steps, you can have a fully functional web development stack that includes MongoDB, Express, Angular, and Node.js. You can use this stack to build powerful web applications with ease.
