PubSub


A simple Pub/Sub implementation for JavaScript that also contains an ask/tell paradigm.

Here is some example usage from some of the tests:

``jsx
import { Pubsub } from 'js-pubsub'

var pubsub = new Pubsub();

it("publish to same topic receives callback with correct argument", () => {
//Arrange
var argResult;
pubsub.subscribe({ toTopic: "arg test", withCallback: result => argResult = result });

//Act
pubsub.publish({ toTopic: "arg test", withData: "it worked" });

//Assert
expect(argResult).to.equal("it worked");
});

it("should allow tellers to answer questions using parameters for context", () => {
//Arrange
//Act
pubsub.answerFor("topic", p1 => answer${p1});

//Assert
expect(pubsub.askFor("topic", 1)).to.equal("answer1");
});
