Setting Up Node.js and Express

To create a RESTful API, start by setting up a Node.js project and installing Express. Use npm to manage dependencies.

Creating API Routes

Define different routes for your API using Express.Router(). Implement CRUD operations by handling HTTP methods like GET, POST, PUT, and DELETE.

Middleware and Error Handling

Utilize middleware functions to enhance your API, such as parsing JSON and handling CORS. Implement error handling middleware to deal with various types of errors.

Database Integration

Connect your API to a database (e.g., MongoDB) using libraries like Mongoose. Create models and perform database operations to store and retrieve data.
