How do I set up a Node.js Express API with a database?

To set up a Node.js Express API with a database, you'll need to install Node.js, Express, and a database driver like Mongoose for MongoDB.

What are the steps to connect my Express app to MongoDB?

First, install Mongoose using npm. Then, create a connection using mongoose.connect() with your MongoDB URI.

Can you show me a sample code for connecting to MongoDB?

Sure! Here's a simple example:

const mongoose = require('mongoose');

mongoose.connect('mongodb://localhost:27017/mydatabase', { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() => console.log('MongoDB connected!'))
  .catch(err => console.error('MongoDB connection error:', err));

What about setting up routes for my API?

You can set up routes in Express using the app.get(), app.post(), etc. methods. Define your routes after initializing your Express app.
