evtm
A lightweight zero-dependency event manager with flexible event type matching
Usage
Initialization:
import {EventManager} from 'evtm';
let eventManager = new EventManager();
Adding a handler of a specific event type:
eventManager.addListener('task started', event => {
console.log(event);
});
Of all events matching the pattern:
eventManager.addListener(/^task\s/, event => {
console.log(event);
});
With captured parameters:
eventManager.addListener(/^(\S+)\s(?<status>.*)$/, event => {
console.log(event.params[0], event.params.status);
});
Adding a handler of all events dispatched to the eventManager
instance:
let listener = eventManager.addListener('*', event => {
console.log(event);
});
Dispatching an event of a specific type and properties:
eventManager.dispatch('task started', {x: 42});
Removing a previously declared listener:
listener.remove();
