Longevity commands?

[Stoupedog]

Yes, you can replicate those commands with Nightbot by making use of the $(twitch) variable and custom api’s

@Minakie

a command that tells you how old your channel is (“Minakie has been sharing Stars for 3 years, 11 months and 29 days.”)

This can be achieved using the built-in $(twitch) variable:
!commands add !channelage Minakie has been sharing Stars for $(twitch Minakie "{{createdLength}}")

@Minakie

a command that let’s you know how long someone has been following you for (“BananaClause followed Minakie on 01-09-2016 11:11:36”)

This will return the date a viewer a viewer followed you:
!commands add !followsince $(urlfetch https://2g.be/twitch/following.php?user=$(touser)&channel=Minakie)

Alternatively, you could use this which will return how long a viewer has been following you:
!commands add !followage $(urlfetch https://api.rtainc.co/twitch/channels/Minakie/followers/$(touser)?format=[1]+has+been+following+[0]+for+[2])

Hope this helped!
