Supergroup (API Reference)

class Supergroup<TContext extends Context = Context>

Supergroup has the same API as Group — every method and property is identical. The only difference is the type discriminant.

Properties

Property	Type
`id`	`number`
`type`	`'supergroup'`
`title`	`string`
`messages`	`MessagesLog<TContext>`
`members`	`Map<number, Membership<TContext>>`

All methods are identical to Group. See Group for complete signatures.

Method	Description
`join(user)`	Add as member
`own(user)`	Set as creator
`promote(user, perms?)`	Make admin
`restrict(user, perms?)`	Restrict user
`changeMemberStatus(user, transition)`	Dispatch `my_chat_member`
`dispatchMemberUpdate(admin, target, status, opts?)`	Dispatch `chat_member`

Use newSupergroup() for modern groups (most Telegram groups are supergroups).
Use newGroup() when testing code that specifically checks chat.type === 'group'.
chats.defaultGroup is a Supergroup.
