I recently completed Stage 0 of the Backend.
The task involved creating a simple RESTful API endpoint that returns personal profile information along with a random cat fact fetched from a third-party API.
Task Overview

The main goal was to build a /me endpoint that:

  • Returns structured JSON data with the following fields:
  • - status
  • - user (containing email, name, and stack)
  • - timestamp (current UTC time in ISO 8601 format)
  • - fact (a random cat fact fetched from the Cat Facts API)
  • Handles API errors gracefully
  • Ensures each request returns a fresh cat fact and timestamp

**

Tech Stack

**

  • Backend Framework: Node.js (Express)
  • Language: TypeScript
  • Testing Tools: Jest & Supertest
  • Deployment Platform: (e.g., Railway / Render / AWS)
  • Version Control: GitHub

**

Key Features

**

  • Integrated a third-party API to fetch live data dynamically.
  • Implemented proper error handling and fallback mechanisms for API failures.
  • Used ISO 8601 format to ensure consistent timestamps.
  • Added automated tests to validate response structure and reliability.

**

What I Learned

**

  • How to consume and handle external API responses effectively.
  • Best practices for structuring a RESTful endpoint.
  • The importance of consistent response formatting and proper HTTP status codes.
  • How to test and verify endpoints using Jest and Supertest.
