Using async/await with Bluebird in Node 7.6.0.

test.js

/* eslint no-console: false */
const bluebird = require('bluebird');

function isBluebirdPromise(promise) {
  return promise.constructor === bluebird;
}

function respond() {
  return new bluebird((resolve) => {
    setTimeout(() => resolve('hi'), 2000);
  });
}

async function respondAsync() {
  return respond();
}

async function intermediate() {
  let promise = respond();
  console.log('`respond` returns Bluebird promise:', isBluebirdPromise(promise));
  return await promise;
}

async function main() {
  console.log('can you await bluebird promises?', await respond() === 'hi');
  console.log('will async avoid double-wrapping bluebird promises?', await respondAsync() === 'hi');

  console.log('but look at the mixed types in the following logs');
  let promise = intermediate();
  console.log('`intermediate` returns Bluebird promise:', isBluebirdPromise(promise));
}

main();
