Plan

What did I do next:

Backend

  1. clear database design, relation between url and user
  2. clear role in the system, guess vs signed-in user
  3. apply clean-architecture => in progress
  • check where JwtModule is placed

  1. setup circle-ci for unit test => OK

5.1 1st Option: how to automatically delete record on postgresql at an expected time will delete when we found that an shortened link requested by an user has expired

  • using pg_cron extension
  • using pgAgent extension
  • using pg_schedule extension
  • using pg_timetable extension 5.2 2nd Option:
  • expose an endpoint to list all expired links and delete them
  • implement a simple batch job to send request to the endpoint above

Frontend

  1. using gatsby to implement UI
  2. base UI to short a link
  3. list of shorten links related to a signed-in user, shorten link will expire in 1 months
  4. list of 10 shorten links generated by guess to guessed, shorten link will expire in 24 hours
