@my-swu/simulator-client / isStaleLobbySnapshot

Function: isStaleLobbySnapshot()

isStaleLobbySnapshot(current, incoming): boolean

Defined in: packages/ts-sdk/src/resources/lobby-snapshot.ts:26

Reports whether incoming is older than the snapshot already held.

Lobby snapshots arrive over two paths — the lobby socket and the snapshot embedded in every HTTP access response — and the two can race. Every persisted lobby change increases revision, so a lower revision is stale and must not replace newer state. Equal revisions are accepted (live connected flags may differ within one revision), and a snapshot without a revision (older server) is never treated as stale.

Example:

import { isStaleLobbySnapshot } from '@my-swu/simulator-client'
import type { LobbySnapshot } from '@my-swu/simulator-client'

export function keepNewestLobbySnapshot(
  current: LobbySnapshot | undefined,
  incoming: LobbySnapshot,
) {
  return isStaleLobbySnapshot(current, incoming) ? current : incoming
}

Parameters

import { isStaleLobbySnapshot } from '@my-swu/simulator-client'
import type { LobbySnapshot } from '@my-swu/simulator-client'

  return isStaleLobbySnapshot(current, incoming) ? current : incoming
}
