userVariables$

Built with
1updateMeta(_meta): Promise<void>

Merges the provided keys into the call’s custom metadata bag, preserving existing keys not mentioned in _meta. To replace the entire bag instead, use setMeta.

The merged metadata is observed via call.meta$ on all connected peers.

Not yet implemented in v4. This method is on the API surface and will throw when called.

Parameters

_meta
Record<string, unknown>Required

Keys to merge into the metadata bag. Other existing keys are preserved.

Returns

Promise<void> — once implemented, resolves after the server has propagated the merged metadata.

Throws

Throws unconditionally — implementation pending.

See

  • setMeta — full-replace alternative.
  • meta$ — observable of the current metadata.
