tiny-emitter-cve-fixes

A tiny (less than 1k) event emitter library. This is a security-focused fork of the original tiny-emitter with fixed CVEs and prototype pollution protection.

Why this fork?

The original repository has not been updated for several years and contains dependencies with known vulnerabilities (CVEs). This fork aims to provide a drop-in replacement that:

• Fixes prototype pollution vulnerabilities.
• Replaces build tooling to avoid vulnerable dependencies

Install

npm

npm install tiny-emitter-cve-fixes --save

Usage

var Emitter = require('tiny-emitter-cve-fixes');
var emitter = new Emitter();

emitter.on('some-event', function (arg1, arg2, arg3) {
 //
});

emitter.emit('some-event', 'arg1 value', 'arg2 value', 'arg3 value');

Alternatively, you can skip the initialization step by requiring tiny-emitter-cve-fixes/instance instead. This pulls in an already initialized emitter.

var emitter = require('tiny-emitter-cve-fixes/instance');

emitter.on('some-event', function (arg1, arg2, arg3) {
 //
});

emitter.emit('some-event', 'arg1 value', 'arg2 value', 'arg3 value');

Instance Methods

on(event, callback[, context])

Subscribe to an event

• event - the name of the event to subscribe to
• callback - the function to call when event is emitted
• context - (OPTIONAL) - the context to bind the event callback to

once(event, callback[, context])

Subscribe to an event only once

• event - the name of the event to subscribe to
• callback - the function to call when event is emitted
• context - (OPTIONAL) - the context to bind the event callback to

off(event[, callback])

Unsubscribe from an event or all events. If no callback is provided, it unsubscribes you from all events.
