Node.js Documentation

Learn how to use Node.js in your BackendGlitch project.

Installing Node.js

To get started with Node.js, you ll need to install it on your system. Follow the instructions for your operating system:

Install Homebrew if you haven t already:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Install Node.js using Homebrew:
```
brew install node
```
Verify the installation:
```
node --version
```

Running Your Node.js Application

Once you have Node.js installed, you can run your BackendGlitch application:

Navigate to your project directory:
```
cd /path/to/your/backendglitch/project
```
Install dependencies:
```
npm install
```
Start your application:
```
npm start
```

Basic Node.js Concepts

Here are some fundamental Node.js concepts used in your BackendGlitch project:

Modules

Node.js uses a module system to organize code. Here's how you can use modules in your project:

// Importing a module
const express = require('express');

// Exporting a module
module.exports = {
  someFunction: function() {
    // Function code here
  }
};

Asynchronous Programming

Node.js uses asynchronous programming to handle I/O operations efficiently. Here's an example using Promises:

function fetchData() {
  return new Promise((resolve, reject) => {
    // Simulating an API call
    setTimeout(() => {
      resolve({ data: 'Some data' });
    }, 1000);
  });
}

async function getData() {
  try {
    const result = await fetchData();
    console.log(result.data);
  } catch (error) {
    console.error('Error:', error);
  }
}

getData();
