Roadmap

• Improve typing for event handlersDONE
• Improve documentation (2 hours)
  • Client-side security explanation
  • Explanation of broadcast vs. local events
  • Explain how to write handlers efficiently/easily
  • Clearly document which operations will not trigger Tyranid events
• TODO: show an example of imperative vs. event handler / i.e. around org-creation / project/plans transition around participants
• Increase context inside event handlers
  • access to current user
    • option 1 -- investigate continuation-local-storage / update Tyr.local
      (it used to be that this was not well-supported, but later versions of node.js added support for async hooks which might / might not make this a performant solution now)
      (4 hours to investigate feasibility + ? hours to implement)
    • option 2 -- ensure people are specifying auth on all tyranid requests
  • access to what was changed / $orig support
    We already support this on historical collections, one solution would be to enable this automatically if
    1. the collection is historical or
    2. the collection has event handlers (4 hours).
• Client-side cache invalidation ... ability to specify force querying a fresh copy in certain circumstances
• Multiple Event Handlers
  • Improve understanding how errors handled/propagated
  • Event transactions ... run all the handlers in a transaction when we go to mongo 4.0 (2 days)
  • Event sequencing -- monad, programmable-semicolon, sequencing
• Create Tyranid developer's document for people who would like to contribute to Tyranid
  investigate https://help.github.com/en/articles/setting-guidelines-for-repository-contributors
• Client-side Projection Management (3 days)
  Includes determining when a cache is missing needed fields.
• devtools for Tyranid
• Unify projection and population syntax
• Use MongoDB 3.6+ aggregations to perform queries that have population in one database operation. This would
  1. reduce the number of queries but also, more importantly, would
  2. allow you to do searching/filtering on populated values when doing a paged query.
• First class support for node.js mongodb driver bulk operations
• Services Roadmap
• Tyreant Roadmap
