Description

Session Goal

The session aimed to develop and debug the backend of a JSON-based web application using Node.js and Express.

Key Activities

• Backend Setup: Initiated the setup of a web server using Node.js and Express, focusing on reading JSON data and creating API endpoints.
• Error Resolution: Addressed common Node.js errors such as ‘server.js not found’ and ‘Cannot GET /’ by verifying file paths and defining root routes.
• Frontend-Backend Integration: Connected the frontend with the backend for a Minimum Viable Product (MVP) using AJAX requests to update the user interface.
• JavaScript Debugging: Resolved JavaScript errors, including Uncaught TypeError by ensuring proper DOM loading and script execution order.
• Server Verification: Conducted server and endpoint verification using Express and tools like Postman to ensure API functionality.

Achievements

• Successfully set up the backend server and established API endpoints.
• Resolved critical errors in Node.js and JavaScript, enhancing application stability.
• Integrated frontend and backend components, allowing dynamic data exchange.

Pending Tasks

• Further testing of API endpoints with varied data inputs.
• Optimization of JavaScript code for better performance and error handling.
