The only one i've used before is Bluebird's `promisifyAll` method.

So when you require libraries, you can do so like:

    const fs = Promise.promisifyAll(require('fs'))
    // ... later    
    const fileContents = await fs.readFileAsync('filename.txt')

Basically it just adds "Async" after all functions that use node style callbacks.
