Backend Challenge - Random Number Generator API

Introduction

The "Random Number Generator API" challenge is designed to build a REST API that generates random numbers based on user-specified parameters.

Objectives

  • Set up a web server capable of handling API requests.
  • Implement an endpoint (/random) that generates random numbers.
  • Allow customization of the generated numbers (e.g., range, quantity).
  • Understand HTTP methods (GET for retrieving data) and status codes.

Instructions

  1. Objective: Develop a REST API that generates random numbers based on user input.

  2. Environment Setup: Choose your preferred programming language (e.g., JavaScript, Python, Java, C#) and set up the necessary environment.

  3. Implementation Details:

    • Create an endpoint (/random) that accepts parameters via HTTP GET requests.
    • Parameters could include min and max for range, and quantity for the number of random numbers to generate.
    • Implement logic to generate random numbers within the specified range and quantity.
    • Return the generated numbers as JSON in the response body.

  4. Testing: Test your API using a HTTP client (e.g., Postman, curl).

    • Send GET requests to the /random endpoint with different parameter values (e.g., min, max, quantity).
    • Verify that the response contains the expected number of random numbers within the specified range.

Possible Improvements

  • Additional Parameters: Add support for additional parameters like seed for reproducibility.
  • Error Handling: Implement error handling for invalid input parameters (e.g., negative range, non-numeric values).
  • Security: Consider security implications, especially if the API is exposed to the public internet.
  • Performance: Optimize the random number generation algorithm for performance, especially with large quantities.

Conclusion

By completing this challenge, you will gain practical experience in developing a REST API that generates random numbers and learn essential practices for backend development. Explore additional improvements and challenges to further enhance your skills.

Happy coding!
