Welcome to the tutorial on how to create a project using the Command Line Interface (CLI). This guide will walk you through the steps to set up a new project from scratch.
Prerequisites
Before you start, make sure you have the following prerequisites:
- A basic understanding of how to use the command line.
- Node.js and npm installed on your system.
Step-by-Step Guide
1. Initialize a New Project
Open your terminal and navigate to the directory where you want to create your project. Then, run the following command:
npm init -y
This command will create a package.json file with default values.
2. Install Dependencies
Next, you can install any dependencies your project requires. For example, if you're building a web application, you might install Express:
npm install express
3. Create a Project Structure
Now, create a basic project structure. You can use the following commands:
mkdir src
mkdir src/models
mkdir src/routes
touch src/index.js
This will create a new directory structure with a src folder, containing models and routes subdirectories, and an index.js file.
4. Write Your Code
Open src/index.js in your favorite text editor and add the following code:
const express = require('express');
const app = express();
app.get('/', (req, res) => {
res.send('Hello, World!');
});
const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
console.log(`Server is running on port ${PORT}`);
});
This code sets up a basic Express server that responds with "Hello, World!" when you navigate to the root path.
5. Run Your Project
Finally, run your project using the following command:
node src/index.js
Your server should now be running, and you can access it at http://localhost:3000.
