Package Exports

promise-to-call

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (promise-to-call) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Promise to Call

Replace callbacks with promises.

Targets to call can be methods of objects (useful "this") or functions (useless "this").

Installation

$ npm install promise-to-call

Usage

const promiseTo = require('promise-to-call');

promiseTo.$callMethod(someObject, 'someMethod', 2, 3)
    .then((data) => { ... })
    .catch((err) => { ... });

promiseTo.$callFunction(someFunction, 2, 3)
    .then((data) => { ... })
    .catch((err) => { ... });

Example

const AWS = require('aws-sdk');
const promiseTo = require('promise-to-call');

function whoAmI() {
    const stsService = new AWS.STS({ region: 'us-east-1' });
    return promiseTo.$callMethod(stsService, 'getCallerIdentity', {})
        .then((data) => {
            return data.Account;
        })
        .catch(console.error);
}

whoAmI().then(console.log); // -> 123456789012

Options

This module uses Promise by default. If you want to use some other class, do this:

promiseTo.usePromiseClass(SomePromiseClass);

promiseTo.usePromiseClass(); // back to using Promise

Tests

$ npm test
