Signals

Lightweight signal libs used as dependancies for my projects.

Signals

Following behaviors may not be properly implemented yet:

• .trigger() should be protected against re-entry.
• removing source/listener should prevent listeners calls even if during trigger.
•  adding listener should trigger in the NEXT event (as it will be called once due to initial).
•  adding source should not cause issue as previous trigger should have been canceled.

Events

import Event from "./?"

const ev = new Event("name"); // name is used for debug.
ev.listen( () => {...} ); // unlisten to stop listening
ev.trigger();

(Un)subscribe(To|From)

• TODO...

EventListener

Recommanded to listen events :

import Event from "./?"
import EventListener from "./?"

const ev = new Event("name");
const l  = new EventListener(ev, () => {});

// called twice.
ev.trigger();
ev.trigger();

import Event from "./?"
import EventListener from "./?"

const ev = new Event("name");
const l  = new EventListener(ev, () => {}, {once: true});

// called once.
ev.trigger();
ev.trigger();

import Event from "./?"
import EventListener from "./?"

const ev = new Event("name");
const l  = new EventListener(ev, () => {}, {ack: true});

// called twice.
ev.trigger();
ev.trigger(); // not called.
l.ack();
ev.trigger();
ev.trigger(); // not called.
