Web analytics master issue

[robbie-c]

Tasks

• Custom channel types
  • Add a preview when creating a new rule, that would show how much traffic from the last week would match that rule
  • Let people save some URLs for testing, and we can show what channel type it would be assigned to
  • Add suggestions for optional built-in rules, like AI or Newsletter. IMO these should continue to update over time, so we should store the IDs in the DB and add the rules at query-time, rather than just adding extra JSON to their custom channel types
• Paths tile
  • Add a button to expand the row, showing extra information about that path
  • Ideate what should go there (add or remove from this list)!
  • Open the toolbar (hint: get the URL with topK(1)(properties.$current_url) or any(properties.$current_url) to get around the fact that it's hard to go from a path-cleaned pathname to a real URL
  • Session replay
  • Error tracking
  • Web vitals
• Icons
  • Add emoji/svgs for device types/browser images
  • Add emoji/svgs for referrers
  • Write background job / something that runs on CI / your laptop that gets favicons for the most popular websites on the internet. Either saves to a DB or checks into version control. See https://github.com/PostHog/posthog/tree/99096dbfe41acccdd537be39ed3ae2068ebc9f03/frontend/public/services for what we have at the moment
  • Add emoji font to fix the problem with Windows Chrome not rendering flag emojis, solution: https://geyer.dev/blog/windows-flag-emojis/ (hard to test it's working on a Mac)
• Data export from web analytics
• Sessions table
  • Create a session view in Activity, showing recent sessions and their events
• Revenue tracking
  • Create clickhouse dictionary for currency conversion
  • Support tracking $ revenue from events
  • Support tracking other currencies
  • Support custom revenue properties from events
  • Support setting up data warehouses sources of revenue (e.g. Stripe, RevenueCat)
