Hello,
We're currently using arangochair (@voondo 's fork in fact, because of authentication issues) and are rather happy with it !
Nevertheless, it would be great to be able to subscribe to insert and update events separately.
This page says that "Separate events for insert and update are currently not possible but will be part of a future update."
Any roadmap for this please ?
Thanks
Please add type 2301 for edge insertion/update events
Do you want help, and in that case have you considered creating a roadmap, documenting how to contribute, adding eslint, unit tests and such?
We are using the latest arangodb version (official docker image for arangodb) and we are getting following error:
This is simple info taken from arangodb dashboards:

@baslr ,
I tried to use ArangoChair inside Arangodb 3.1.21, but later I realised that Arangodb has not implemented http and https node modules. It will be great if you can make this compatible with Arangodb foxx.
Thanks & Regards,
Sajeev Ramakrishnan
Have you noticed any performance problems with ArangoDB while running this? I'm seeing the CPU utilization of ArangoDB running a fairly consistent 30% CPU when running and the HD seems very active. This isn't necessarily a bug of this project, but wanted to verify that others are seeing this happen as well.
For anyone trying to use the library.
I was trying to use the keys filter, this initially didn't return any value.
Dug a little and discovers on line 96:
if (0 !== keys.size && !events.has(key)) return;
Should be:
if (0 !== keys.size && !keys.has(key)) return;
when a collection is renamed, arangochair cant find any updates.
cause: the wal writes the old collection name.
