How do I set up a database with Express?

To set up a database with Express, you typically use a database like MongoDB or PostgreSQL. Which one are you considering?

I'm thinking of using MongoDB. What are the steps?

First, install MongoDB and the Mongoose library. Then, connect to your database in your Express app using Mongoose.

Can you show me a code example for the connection?

Sure! Here's a basic example:

const mongoose = require('mongoose');

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