Getting Started with Your First App

Welcome to the guide on building your first app with our platform! This document will help you set up your development environment and create a simple application.

Prerequisites

Before you begin, ensure that you have the following installed:

  • Node.js (version 14 or higher)
  • npm (Node Package Manager)

Setting Up Your Environment

  1. Install Node.js: Download and install Node.js from the official website.
  2. Verify Installation:
    node -v
npm -v
    Ensure that both commands return version numbers indicating successful installation.

Creating Your First App

Now that your environment is set up, let's create a simple application.

Step 1: Initialize Project

Open your terminal and run:

mkdir my-first-app
cd my-first-app
npm init -y

Step 2: Install Dependencies

Next, install the necessary package:

npm install express

Step 3: Create Your App

Create a file named app.js:

const express = require('express');
const app = express();
const PORT = process.env.PORT || 3000;

app.get('/', (req, res) => {
    res.send('Hello World!');
});

app.listen(PORT, () => {
    console.log(`Server is running on http://localhost:${PORT}`);
});

Step 4: Run Your App

Finally, start your application by running:

node app.js

Visit http://localhost:3000 in your web browser, and you should see the message "Hello World!" displayed.
