The EventSub implementation is very basic right now, but it needs to be ready in the near future (https://discuss.dev.twitch.com/t/legacy-pubsub-deprecation-and-shutdown-timeline/58043). A few tasks that need to be done at some point (feel free to update) and I can't keep them all in my head or in the TODO.md file.

twitch-eventsub-ws

• Default of json_transform should be snake_case since it will be used most #5911
• Automatically infer timestamp for std::chrono types (currently json_tag=AsISO8601) #5912
• Get rid of clang-tidy warnings in generated code (trivial moves and unnamed arguments) #5913
• The generated implementation code (.cpp) starts with an empty line #5909
• Parse inner data of mutually exclusive fields as sum types (std::variant or similar) or using inheritance. channel.moderate's Event is currently 3336 bytes large (81% of a page on most systems) #5917
• Add unit tests (we already have googletest in the repository) #5918
• Run pytest in CI #5919

Chatterino Integration

• The websocket connections need to die when user is changed #5926
• Should the client reconnect when the auth token is updated? #5929
• Check on behavior if PubSub is shut down (Do we get errors? Do reward messages come through? etc.) #5928
• Deserialize types in-place (as opposed to returning a result<T> and moving) #5927
• Reconnect after network outage fix(eventsub): close connection after timeout #6059 fix(eventsub): check keepalive #6058
• Use Qt's logging instead of std::cerr fix: use qlogging in eventsub lib (through a hoop) #6161

PubSub Parity

• moderation.chatCleared (handled by channel.moderate clear feat(eventsub): implement clearchat #5981)
• moderation.messageDeleted (handled by channel.moderate (shared_chat_)delete feat(eventsub): implement (shared chat) delete #5993)
• moderation.modeChanged (handled by channel.moderate feat(eventsub): implement mode changes #5992)
• moderation.moderationStateChanged (handled by channel.moderate (un)mod feat(eventsub): implement (un)mod #6001)
• moderation.raidStarted (handled by channel.moderate raid feat(eventsub): Add support for /(un)raid #6002)
• moderation.raidCanceled (handled by channel.moderate unraid feat(eventsub): Add support for /(un)raid #6002)
• moderation.userBanned (handled by channel.moderate (shared_chat_)ban feat(eventsub): implement (shared-chat-)ban #5985 and (shared_chat_)timeout feat(eventsub): implement (shared-chat) timeout #5995)
• moderation.userUnbanned (handled by channel.moderate unban and shared_chat_unban feat(eventsub): implement unban #5990)
• moderation.userWarned (handled by channel.moderate warn feat(eventsub): Add support for channel.moderate Warn #5932)
• moderation.suspiciousMessageReceived (handled by channel.suspicious_user.message feat(eventsub): implement suspicious user message #6007)
• moderation.suspiciousTreatmentUpdated (handled by channel.suspicious_user.update feat(eventsub): implement suspicious user update #6012)
• moderation.autoModMessageCaught (handled by automod.message.hold feat(eventsub): implement automod message hold #6005 and automod.message.update feat(eventsub): implement automod message update #6010)
• moderation.autoModMessageBlocked (handled by automod.message.update) was superseded by autoModMessageCaught but never removed
• moderation.automodUserMessage (handled by channel.moderate {add,remove}_{permitted,blocked}_term feat(eventsub): implement AutoMod term actions #6000)
• moderation.automodInfoMessage (handled by channel.chat.user_message_{hold,update} feat(eventsub): implement channel.chat.user_message_(hold/update) #6008)
• Respect streamerModeHideModActions refactor(eventsub): Respect "Hide moderation actions" explicitly #6041
• Stack timeouts (feat(eventsub): implement timeout stacking #6013)

If you haven't done yet, please vote on "Allow getting realtime updates on polls/predictions/channel points redemptions through websockets for all users". We can't display reward information on channel point redemptions without PubSub. In EventSub, these subscriptions are hidden behind broadcaster authentication. There are ideas to work around that, but they require a dedicated server (RFC).

Some nice-to-have things:

• String could be 4 pointers large instead of 5 by using a custom SSO (i.e. union { QString, short-string, alloc'd string }) #5921
• Could we get rid of the .inc files? Either by manually writing the declarations for tag_invoke or by using a macro. #5922
• Avoid const in parsed values because it implicitly deletes move operations #5923
• Implement HTTP proxying for EventSub #5924
• Implement SOCKS5 proxying for EventSub (would require another dependency) #5925
• De-duping automod.message.hold matched terms #6006
• date.h should be included as a submodule #6047
