Interface: Reactor

The reactor coordinates the update of registered Reactions.

Reactions are created with createReaction()
reaction.track(effect) will run the effect and associate any engine read calls during the execution with the Reaction.
reaction.subscribe(handler) will invoke the handler whenever the engine read calls in the reaction might have changed after an update.

Methods#

createReaction(debugName?): Reaction;

Create and return a new Reaction that is associated with this Reactor.

Parameter	Type
`debugName?`	`string`

dispose(): void;

Dispose the reactor and all reactions. After this call, the reactor is no longer usable.

void

Property	Type	Description
`nextReaction`	`Promise`<`void`>	A promise that will resolve after the next update of the Reactor. This can be used to wait for the next update of the Reactor in an async function. `await reactor.nextReaction;` This is useful in situations where you want to make sure that the effects of a reactor update have propagated to any dependent code before continuing. Particularly, this can be used to ensure that the UI has updated before continuing with other operations.
