This is a simple URL shortener project built in Java. It uses Javalin to handle REST requests. It stores information about URLs in a database. You can currently choose between SQLite, MySQL and MongoDB.

There is also a frontend that is made with Svelte.

Users are required to have an account before they can create urls. They will receive an JWT token after logging in.

curl --location 'http://localhost:8020/api/auth/register' \
--header 'Content-Type: application/json' \
--data '{"username": "YOUR_NAME", "password": "YOUR_PASSWORD"}'

curl --location 'http://localhost:8020/api/auth/login' \
--header 'Content-Type: application/json' \
--data '{"username": "YOUR_NAME", "password": "YOUR_PASSWORD"}'

This command sends a POST request to the /api/create endpoint with the original URL as JSON data. The server will generate a short URL for the provided URL.

curl --location 'http://localhost:8020/api/create' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer YOUR_TOKEN_HERE' \
--data '{"url": "https://www.youtube.com/watch?v=dQw4w9WgXcQ"}'

The response will look like this

{"url":"tQYC5b"}

This command sends a GET request to the /api/stats/{code} endpoint, where {code} represents the short URL code. The server will return information about the URL, including the original URL and the number of redirects. Make sure to replace tQYC5b with the actual short URL code.

curl --location 'http://localhost:8020/api/stats/tQYC5b'

The response will look like this

{"original_url":"https://www.youtube.com/watch?v=dQw4w9WgXcQ","redirects":0,"shortened_url":"tQYC5b"}

Once a URL is shortened, you can access it using the shortened URL, for example:

http://localhost:8020/tQYC5b

To launch the frontend run the following command in the frontend directory

npm run dev -- --open
