grove.memberBadges.set()

Replace native badges beside channel members.

Signature

grove.memberBadges.set(badges: {
  id: string; channelKey: string; memberKey: string;
  icon?: string; text?: string; tooltip?: string
  color?: 'neutral' | 'accent' | 'success' | 'warning' | 'danger'
}[]): void

Availability

Server-scoped runtimes with ui.member-badges. Reading authoritative target data requires the corresponding channel.members or channel.metadata capability separately.

Parameters

Parameter	Required	Description
`badges`	Yes	Full replacement array; [] clears all.
`id`	Yes	Local badge identity per target; trimmed/lowercased, capped at 64 characters, nonempty.
`channelKey`	Yes	Host-canonical channel key; nonempty, at most 200 UTF-8 bytes.
`memberKey`	Yes	Host-canonical member key; nonempty, at most 200 UTF-8 bytes.
`icon`	At least icon or text	SF Symbol name, single-line and capped at 64 characters.
`text`	At least icon or text	Single-line label, capped at 32 characters.
`tooltip`	No	Single-line explanation, capped at 120 characters.
`color`	No	Semantic tint, default neutral; unknown values use neutral.

Return value

Returns undefined; no validation report or list is returned.

Behavior and errors

The call replaces the whole list atomically. Mango retains at most two badges per target per instance and 8,192 total, inspecting at most 32,768 candidates. Duplicate target/id entries keep the first. Empty/unrenderable entries are omitted. Use canonical keys from snapshots instead of lowercasing display names yourself. Rendering requires the target to exist; registrations grant no access to a missing roster. Mango provides attribution and removes contributions when the instance stops.

Example

grove.on('channelSnapshots', ({ channels }) => {
  grove.memberBadges.set(channels.flatMap(channel => (channel.members || []).map(member => ({
    id: 'mode', channelKey: channel.channelKey, memberKey: member.memberKey,
    text: member.prefixes || 'member', color: 'neutral'
  }))))
})
