4. Step-by-Step Guides, Tutorials, and Examples

4.1. Setting up a Lithe Project

Install Node.js: Download and install the latest version of Node.js from the official website.
Create a Project Folder: Create a new folder for your Lithe project.
Initialize npm: Open the project folder in your terminal and run npm init -y to create a package.json file.
Install Lithe: Run npm install lithe to install the Lithe framework.

4.2. Creating Your First API Endpoint

const Lithe = require('lithe');

const app = new Lithe();

app.get('/hello', (req, res) =&gt; {
  res.json({ message: 'Hello from Lithe!' });
});

app.listen(3000, () =&gt; {
  console.log('Server listening on port 3000');
});

This code creates a simple API endpoint that responds with a JSON object when accessed at the http://localhost:3000/hello URL.

4.3. Adding Middleware

const Lithe = require('lithe');
const morgan = require('morgan'); // Middleware library for logging requests

const app = new Lithe();

app.use(morgan('dev')); // Log requests to the console

app.get('/hello', (req, res) =&gt; {
  res.json({ message: 'Hello from Lithe!' });
});

app.listen(3000, () =&gt; {
  console.log('Server listening on port 3000');
});

This code adds a middleware function to log every incoming request to the console using the morgan library.

4.4. Handling Data with Databases

const Lithe = require('lithe');
const { MongoClient } = require('mongodb'); // MongoDB driver library

const app = new Lithe();

const uri = 'mongodb://localhost:27017'; // Replace with your MongoDB connection string
const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true });

app.get('/users', async (req, res) =&gt; {
  try {
    await client.connect();
    const db = client.db('mydatabase');
    const usersCollection = db.collection('users');
    const users = await usersCollection.find({}).toArray();
    res.json(users);
  } catch (error) {
    console.error(error);
    res.status(500).json({ error: 'Failed to fetch users' });
  } finally {
    await client.close();
  }
});

app.listen(3000, () =&gt; {
  console.log('Server listening on port 3000');
});

This code demonstrates how to interact with a MongoDB database using the mongodb driver library.
