GitHub Issue Forms Body Parser

Test Release Conventional Commits zentered.co

Issue Forms is a great way to structure GitHub Issues to an expected format, and to make it easier to capture information from the user. Unfortunately, the schema only defined the input of the data, not the output. So the markdown body needs to be parsed to extract the information in a structured way and to make further processing easier.

We use this Action at the Cyprus Developer Community to create issues with event data for upcoming meetups etc. The parser extracts the information from the issues and provides structured data to create calendar entries (ie .ics files for calendar subscriptions with GitEvents), calling 3rd party APIs, etc.

Inspired by: Peter Murray's Issue Forms Body Parser with valuable feedback from Steffen

Parsers

  • date: checks if the value matches a common date format and returns a formatted date field (in UTC).
  • time: checks if the value matches a common time format and returns a formatted time field.
  • lists: automatically returns lists as arrays
  • duration: currently only the format XXhYYm is supported as duration, ie. 1h30m returns a duration object with hours and minutes.
