NewsBytes Backend Assignment | UrlShortner

# Problem Statement

Write a URL Shortener Service which provides below functionalities
1. Get Short Url from Long Url
2. Get Long Url from Short Url

This Project also contains the utility functions for DynamoDB CRUD operation in Python

Note:- This Project only handles the url having BASE URL = https://www.newsbytesapp.com/

# Tech / Framework Used

• DynamoDB

# APIs Details

1. Get Shorl Url

{{host}}/api/v1/urlShortner/tiny-url?long_url=https://www.newsbytesapp.com/......

2. Get Original Url

{{host}}/api/v1/urlShortner/long-url?short_url=https://www.newsbytesapp.com/......

# Approach used in the Project

• I have used md5 hash to generate unique identifoer for each url, chances of collision of md5 hash is approximately: 1.47*10-29
• Used DynamoDB to store tiny_url and long_url
• DynamoDB ---- primary_key -- tiny_url
• Used NoSQL DB for scalability and as no SQL operations are required

# Example :-

Long URL ---
