πŸš€ HNG13 Stage 0 (Backend Track)

#hng #backend #api #node

Hey everyone πŸ‘‹

I just completed Stage 0 of the HNG13 Internship (Backend track), and it’s been an awesome start already!

For our first task, we were asked to build a Dynamic Profile Endpoint API that returns our personal information along with a random cat fact fetched from an external API. 🐱

πŸ’‘ What the task was about

The goal was to:

  • Build a simple backend API with Node.js and Express
  • Fetch data from a third-party API (Cat Fact API)
  • Return both static and dynamic JSON data
  • Implement rate limiting for better security and performance
  • Handle errors properly and follow clean API design principles
  • This project tested our understanding of APIs, JSON, error handling, and rate limiting; all essential backend skills.

🧰 Tech Stack

  • Backend: Node.js / Express
  • Rate Limiter: express-rate-limit
  • External API: Cat Fact API

βš™οΈ Setup Guide

To run the project locally:

Clone the repository 

git clone https://github.com/Jamal-09/hng_stage_0.git
Enter fullscreen mode Exit fullscreen mode

Navigate into the folder

GET /me

Returns my profile information, timestamp, and a random cat fact.

{
  "status": "success",
  "user": {
    "email": "napg.adekunle@gmail.com",
    "name": "Jamal Ademola",
    "stack": "Node.js/Express"
  },
  "timestamp": "2025-10-15T19:35:01.868Z",
  "fact": "A group of cats is called a β€œclowder.”"
}
Enter fullscreen mode Exit fullscreen mode
