promise.allsettled

promise.allsettled

ES Proposal spec-compliant shim for Promise.allSettled. Invoke its "shim" method to shim Promise.allSettled if it is unavailable or noncompliant. Note: a global Promise must already exist: the es6-shim is recommended.

This package implements the es-shim API interface. It works in an ES3-supported environment that has Promise available globally, and complies with the proposed spec.

Most common usage:

var assert = require('assert');
var allSettled = require('promise.allsettled');

var resolved = Promise.resolve(42);
var rejected = Promise.reject(-1);

allSettled([resolved, rejected]).then(function (results) {
	assert.deepEqual(results, [
		{ status: 'fulfilled', value: 42 },
		{ status: 'rejected', reason: -1 }
	]);
});

allSettled.shim(); // will be a no-op if not needed

Promise.allSettled([resolved, rejected]).then(function (results) {
	assert.deepEqual(results, [
		{ status: 'fulfilled', value: 42 },
		{ status: 'rejected', reason: -1 }
	]);
});
