resolve-value

Deeply resolve all promises in a value.

Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your ❤️ and support.

Install

Install with npm (requires Node.js >=10):

$ npm install --save resolve-value

Usage

const resolve = require('resolve-value');

Examples

assert.equal(await resolveValue(10), 10); //=> 10
assert.equal(await resolveValue(Promise.resolve(10)), 10); //=> 10

Functions

By default all functions are called.

assert.equal(await resolveValue(() => Promise.resolve(10)), 10); //=> 10
assert.equal(await resolveValue(async () => Promise.resolve(10)), 10); //=> 10

Pass a custom replacer function as the second argument to override this behavior.

const obj = { fn: () => 'do nothing', num: Promise.resolve(10) };

const result = await resolveValue(obj, (value, parent) => {
  if (parent && parent.someKey === true) {
    return value;
  }
  return value();
});

console.log(result.fn); //=> [Function: fn]

Objects

Resolves all property values, including functions.

const obj = { foo: async () => delay('bar', 10), num: Promise.resolve(10) };
const actual = await resolve(obj);
//=> { foo: 'bar', num: 10 }

Deeply nested

const obj = { foo: async () => delay('bar', 10), num: Promise.resolve(10) };
const arr = [obj, Promise.resolve(1), Promise.resolve(() => 2)];

const actual = await resolve(arr);
//=> [ { foo: 'bar', num: 10 }, 1, 2 ]
