Custom Events

The service in charge of the events is the EventManager service.

Usage

Registering

In order to register an event, use the @OnCustom() decorator like this:

import { OnCustom } from '@/decorators'

export class YourEventHandler {

    @OnCustom('myCustomEvent')
    handleMyCustomEvent() {

        console.log('I handled my custom event!')
    }
}

It should be placed under the src/events/custom/ folder.

Emitting

In order to emit an event, use the emit() method on any injected instance of EventManager:

import { Service } from '@/decorators'
import { EventManager } from '@/services'

@Service()
export class YourService {

    constructor(
        private eventManager: EventManager
    ) {}

    doSomething() {

        this.eventManager.emit('myCustomEvent')
    }
}

Parameters

Here is a simple example that demonstrates how to pass parameters to an event:

import { OnCustom } from '@/decorators'

export class YourEventHandler {

    @OnCustom('myCustomEvent')
    handleMyCustomEvent(x: number, name: string) {

        for (let i = 0; i < x; i++) {
            console.log(`Hello ${name}!`)
        }
    }
}

import { Service } from '@/decorators'
import { EventManager } from '@/services'

@Service()
export class YourService {

    constructor(
        private eventManager: EventManager
    ) {}

    doSomething() {

        this.eventManager.emit('myCustomEvent', 3, 'John Doe')
    }
}
