monologue.js | Observer pattern based pub/sub utility

monologue.js is a JavaScript library. monologue.js has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can install using 'npm i monologue.js' or download it from GitHub, npm.

monologue provides 'event-emitting' functionality - commonly referred to as "pub/sub" - that can be mixed into/inherited by your JavaScript objects. monologue's pub/sub implementation uses the observer pattern - meaning that subscribers should have a direct reference to the 'monologue-ized' object emitting the events. This is in contrast to monologue's sister library, postal.js, which uses the mediator pattern to relieve publishers and subscribers from the need to have a direct reference to each other. Putting a monologue instance in the prototype chain of an object turns it into an "event emitter". This is incredibly useful in organizing how other local (within a limited scope/module) instances are notified of something the object wants to publish. monologue is designed to be bridged with postal.js if you want to 'promote' an event into an app-level message - and the monopost add-on exists to do just that.
