We need your help migrating a legacy social network service.
This service have users that can friend other users and offers an HTTP API to do so.
The solution can be implemented either in Java 11 or Kotlin.
The use cases that need to be implemented are:
- Sign up
- A new user requests to register to our service, providing its username and password.
- Username must be unique, from 5 to 10 alphanumeric characters.
- Password from 8 to 12 alphanumeric characters.
- Request friendship
- A registered user requests friendship to another registered user.
- A user cannot request friendship to himself or to a user that already has a pending request from him.
- Accept friendship
- A registered user accepts a requested friendship.
- Once accepted both users become friends forever and cannot request friendship again.
- Decline friendship
- A registered user declines a requested friendship.
- Once declined friendship can be requested again.
- Friends
- List friends of a registered user.
Make sure docker is started and execute:
No database needed, you can persist everything in memory.
We expect from you to apply good practices and be proud of what you do. Good luck!
