OnPromise

Solve promises using events

Install

npm install --save onpromise

Usage

Create a new emiiter.

const PromiseEmitter = require("onpromise");

var pe = new PromiseEmitter();

Resolve and create promise

// Resolve the 'add' promise
pe.resolve('add', (promise, a, b)=>{
	promise.resolve( a+b );
});

// Create a promise called 'add' and provide arguments. As many arguments as necessary can be supplied
pe.promise('add', 5, 4).then(
	(res) => {
		console.log('5 + 4 = ', res);
	}
);

Promises can also be created before a resolver exists.

pe.promise('multiply', 5, 4).then(
	(res) => {
		console.log('5 x 4 = ', res);
	}
);

pe.resolve('multiply', (promise, a, b)=>{
	promise.resolve( a*b );
});

A timeout can be set. If a promise is not resolved/rejected within the given timeout, it is automatically rejected. The default timeout is 1000ms

pe.promise(20, 'multiply', 5, 4).then(...); // Will timeout after approx 20 milliseconds
