resolve-nested-promises

What for?

To resolve nested promises in object properties, arrays, arrays of object with promises etc.

It is like Bluebird's Promise.props but with native promises, nested props, and arrays support!

Installation

Simply install through npm:

npm i resolve-nested-promises

Usage

From this package only one function is exported as a named export and a default export.

import { resolveNestedPromises } from 'resolve-nested-promises'
// or
import resolveNestedPromises from 'resolve-nested-promises'
// or
const resolveNestedPromises = require('resolve-nested-promises')

This function takes one parameter of any type, and always returns a Promise that resolves to:

1. That param - if it is a primitive
2. Promise resolve value - if it is a promise
3. Array of resolved values - if it is an array of promises (like Promise.all)
4. Object with resolved values in place of Promise properties (nested Promise properties too!) and rest of properties preserved.
5. Any mix of nested objects, arrays, arrays with object. All promises resolved!

Examples

Check tests folder for more examples!

resolveNestedPromises(null) // resolves to null

resolveNestedPromises('String value') // resolves to 'String value'

resolveNestedPromises([Promise.resolve('a'), Promise.resolve('b')]) // resolves to ['a', 'b']

resolveNestedPromises({ a: Promise.resolve('a'), b: 'b' }) // resolves to { a: 'a', b: 'b' }
