Portals is a library for dealing with asynchronous event-driven architecture in two ways. The first is the run-of-the-mill event bus with a different way of handling context. The second provides a way of declaring services with multiple endpoints for those that don’t like the “ping-pong” concept in all cases; endpoints are tappable, lockable, and securable.

Install

npm install @ao-framework/portals

Global Reference Location

import Portals from "@ao-framework"

export default new Portals();

Event Bus

import portals from "./global.reference"

class AppState {
    public constructor() {
        portals.bus("app.state")
            .on("something", this.doSomething, this)
            .on("something.else", this.doSomething, null)
    }

    public doSomething() {}

    public unregister() {
        portals.bus("app.state")
            .removeListener("something", this.doSomething)
            .removeListener("something.else", this.doSomething)
    }
}

Service

class AppState {
    public constructor() {
        portals.service("app.state")
            .route("get.users", this.getUsers, this)//can be changed and tapped
            .routeTap("get.users", logger.debugSync, logger)
            .routeLock("get.users", this.getUsers, null)//cannot be changed
            .routeLockSec("get.users", this.getUsers, null)//cannot be tapped
    }
    //...
}

portals.services("app.state")
    .request("get.users", ...args)
    .then(users => console.log(users))
