p-reflect

> Make a promise always fulfill with its actual fulfillment value or rejection reason

Useful when you want a promise to fulfill no matter what and would rather handle the actual state afterwards.

Install

``
$ npm install p-reflect
`

Usage

Here, Promise.all would normally fail early because one of the promises rejects, but by using p-reflect, we can ignore the rejection and handle it later on.

`js
import pReflect from 'p-reflect';

const promises = [
getPromise(),
getPromiseThatRejects(),
getPromise()
];

const results = await Promise.all(promises.map(pReflect));

console.log(results);
/*
[
{
status: 'fulfilled',
value: '🦄'
isFulfilled: true,
isRejected: false
},
{
status: 'rejected',
reason: [Error: 👹]
isFulfilled: false,
isRejected: true
},
{
status: 'fulfilled',
value: '🐴'
isFulfilled: true,
isRejected: false
}
]
*/

const resolvedString = results
.filter(result => result.isFulfilled)
.map(result => result.value)
.join('');

console.log(resolvedString);
//=> '🦄🐴'
`

The above is just an example. Use p-settle if you need exactly that.
