📤 Helpers for managing state effects in boardgame.io.

This package provides a structured approach to triggering ephemeral “effects” in game code that can be consumed from state on the client. It provides a game plugin and a client-side extension that emits events for your effects.

npm i bgio-effects

Call effects from your moves or other game code:

function move(G, ctx) {
  ctx.effects.explode();
}

Listen for effects on the client:

const onExplode = () => {
  // render explosion/play sound/etc.
};

// With the plain JS emitter
emitter.on('explode', onExplode);

// With the React hook
useEffectListener('explode', onExplode, []);
