p-is-promise Build Status

Check if something is a promise

Why not is-promise? That module checks for a thenable, not an ES2015 promise. This one is stricter.

You most likely don't need this. Just pass your value to Promise.resolve() and let it handle it.

Can be useful if you need to create a fast path for a synchronous operation.

Install

$ npm install --save p-is-promise

Usage

const pIsPromise = require('p-is-promise');
const Bluebird = require('bluebird');

pIsPromise(Promise.resolve('🦄'));
//=> true

pIsPromise(Bluebird.resolve('🦄'));
//=> true

pIsPromise('🦄');
//=> false
