Backend API Development

Welcome to Module 3! In this module, we shift our focus to the server-side. We will be building the backend for our Task Manager application using Hono.js.

What You Will Learn

In this module, we will cover:

• Routing Fundamentals: Handling different HTTP methods (GET, POST, etc.) and route parameters.
• Middleware: Intercepting requests for logging, authentication, and error handling.
• Mocking APIs: Creating placeholder endpoints to unblock frontend development.
• API Testing: Using Postman to test and verify your API endpoints.

The Role of the Backend

The backend is the brain of our application. It handles:

1. Data Persistence: Storing and retrieving tasks from the database (we’ll mock this first).
2. Business Logic: Validating data and enforcing rules (e.g., “a task must have a title”).
3. Security: Ensuring only authorized users can access their data.

Our Tech Stack

• Framework: Hono.js (Fast, lightweight, web-standard based)
• Runtime: Cloudflare Workers (Serverless)
• Testing Tool: Postman
