register-listeners

register multiple event listeners at once for nodeJS.

intro

Originally created in 24 - 01 - 2021

Normally, when you want to add multiple event listeners in JavaScript, you would do it like this:

const server = app.listen(port) // say for example you're using expressJS

server.on("listening", ()=> log.info("listening on port 3000..."));
server.on("error", ()=> log.error("error! 🔥️"));

Using register-listeners:

const server = app.listen(port)

registerListeners(server, {
	listening: ()=> log.info("listening on port 3000..."),
	error: ()=> log.error("error! 🔥️")
})

Using register-listeners is a lot cleaner if you're registering more and more event listeners.

Usage

registerListeners(on, obj)

argument	Description
on	The emitter that you want to listen for its' events, for example: the express server as shown in the example above.
obj	a key value pair representing the following:  the key: is the exact name of the event that you want to listen for. the value: a callback function that you want to execute if that event was emitted.

Side note about the log() function

The log.error() and log.info() functions that I used in the code above is from @samislam/log, it's a simple module that helps you to print colorful output to your console, which makes the development process a lot easier. to you can download it from npm.
