How to force a re-render?

[pbastowski]

Nice library, thanks for creating it.

I want to re-render my component based on some condition, such as an updated in an imported reactive store. In lit-element I would call this.requestUpdate() to do that.

How do I request an update (re-render) in fuco?

You can use a reducer that always returns a different value with useReducer to force update.
Here is an example:

const [, forceUpdate] = useReducer<number, void>(x => x + 1, 0);

function subscribe() {
  forceUpdate();
}
