URL Shortener (Backend)

Design and develop the backend of URL shortener service that takes in a valid URL and returns a shortened URL, redirecting the user to the previously provided URL

Also keep track of total visits/clicks on the URL

Routes

• POST/URL - Generates a new short URL and returns the shortened URL in the format example.com/random-id
• GET/:id - Redirects the user to the original URL
• GET/URL/analytics/:id - Returns the clicks for the provided short id

Technologies Used

• Used shortid library of npm to generate short id of the given urls
• Used MongoDB to store and track urls data
• Used Express as a middleware to parse incoming bodies
• Used Postman for REST API routes call and check status

Steps to start the project

• npm install should install all the dependencies of this project
• npm start runs the index.js file
• open a new terminal and type mongosh to start connecting the MongoDB database
• Enter Command show dbs lists the number of database created
• Then show collections -> urls
• Next db.urls.find({}) -> It will be blank first but after creating the shortId and redirectURL it shows list of urls as object
• download postman locally to get access to REST API calls for the local project otherwise if you use web version of postman it will show error
