Url Shortener

Main target of this project was to learn Docker and Docker Compose.
But to dockerize some app, you first need to create this app, huh.
And I think an url shortener is one of the best apps for this purpose.
It is simple application that able to shorten specified link.
Example: https://very-long.domen.com/article-title -> https://sh.com/Hd51d
MongoDB is used as a data base to make app fast.
iOS client: https://github.com/theimaginationless/url-shortener-ios-client

How to build and run App + MongoDB using Docker

  • cd ./url-shortener
  • docker-compose up --build

Now you can access url-shortener at localhost:8080 and mongodb at localhost:27017.
MongoDB data is persisted between containers restarts.
Db name and credentials may be found in application.properties.

How to use

Once application is started you can post long url to receive shortened version:

  • POST /shortenUrl with body { "sourceUrl": "https://very-long.domen.com/article-title" }
  • Receive something like { "sourceUrl": "https://very-long.domen.com/article-title", "shortenedUrl": "http://localhost/Hd51d" }

And than

  • GET /Hd51d to be redirected to https://very-long.domen.com/article-title
