Good luck and have fun ☘️

Prerequisites:

The already built up code frame in this repo is a very basic API with limited functionality. Your task is to pick it up and develop new features on top of it.

You can change existing code structure however you can't add any external frameworks and third party classes.

There is an SQLite database (testDb.db) which is created and filled on the fly.

There is a basic routing in index.php which supports GET and POST calls in particular:

  • GET constructionStages
  • GET constructionStages/{id}
  • POST constructionStages

The API serves data and accepts payload only in JSON format.

Task 1:

Add a new API call PATCH constructionStages/{id} which to allow the API users to edit an arbitrary field of a selected (by id) construction stage. The API should touch only the fields which are sent by the user. Add validation which to ensure that if status field is sent it is either NEW, PLANNED or DELETED and throw a proper error if it is not.

Add another DELETE constructionStages/{id} API call which changes the status of the selected resource to DELETED.

Task 2:

Write a validation system which checks every posted field against a set of rules as follows:

  • name is maximum of 255 characters in length
  • start_date is a valid date&time in iso8601 format i.e. 2022-12-31T14:59:00Z
  • end_date is either null or a valid datetime which is later than the start_date
  • duration is skipped because it should be automatically calculated based on start_date, end_date and durationUnit
  • durationUnit is one of HOURS, DAYS, WEEKS or can be skipped (which fallbacks to default value of DAYS)
  • color is either null or a valid HEX color i.e. #FF0000
  • externalId is null or any string up to 255 characters in length
  • status is one of NEW, PLANNED or DELETED and the default value is NEW.

You should throw proper errors if a rule is not met.

Task 3:

Set a logic which automatically calculates duration based on start_date, end_date and durationUnit as you know that:

  • start_date is required and is a valid date&time in iso8601 format i.e. 2022-12-31T14:59:00Z
  • end_date is either null (then duration is also null) or a valid datetime which is later than the start_date
  • durationUnit is one of HOURS, DAYS, WEEKS where DAYS is the default fallback.
  • duration is a positive float value calculated in precision of whole hours (ignore minutes and seconds if any)
  • a week has 7 days and one day has 24 hours

Default task:

Add a nice phpDoc to every method you create!

Bonus task:

Add a system which generates a documentation out of your API!
