👋 @Zach Klippenstein (he/him) [MOD] My workflow question of the day: can the lifetime of a Flow worker go beyond a single Action ? I want to subscribe to a Flow for the lifetime of a workflow, but it looks like any subsequent action would cancel the Flow immediately and you have to re-subscribe to the flow in the next render call. I remember reading that it’s possible to subscribe to external event sources, but this is not how I expect Flow worker to work so I’m probably doing something wrong.

[Ray Ryan]

The worker will keep running, and stay subscribed, so long as you make an identical runningWorker call on each render.

[Ray Ryan]

Where identical means that doesSameWorkAs returns true, and the optional key param to runningWorker matches.

[Ray Ryan]

For the kind of always-running thing you’re talking about, I’ll usually have that runningWorker call as the first line of my render, before when(state) or whatever.

Thanks Ray! it’s all working as expected now. I thought I needed to have the runningWorker call in one of the when(state) branch to avoid re-subscribing to the flow. The way it memorises existing worker is cool and it makes things look more declarative 👍

That was the intention, try to make things look as declarative as possible. Thanks for the feedback 🙂
