From 0fd9d29d392ece68550977b3c7fce41cc147ba9f Mon Sep 17 00:00:00 2001 From: Alex Potsides Date: Wed, 25 Oct 2023 06:26:42 +0100 Subject: [PATCH] refactor!: remove isStarted method from Startable (#2145) We have an `isStarted` method on the `Startable` interface but we only really use it in tests. Our implementations tend to guard on being started twice so it just adds noise to every implementation. BREAKING CHANGE: the `isStarted` method has been removed from the `Startable` interface --- doc/migrations/v0.46-v1.0.0.md | 17 ++ .../src/pubsub/api.ts | 2 - packages/interface/src/startable.ts | 2 -
