Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

co-authy

An Authy client for node.js using generators via co.

Status

This module has been deprecated in favour of authy-client, a complete Authy client with support for TOTP, OneTouch, Phone Verification and Phone Intelligence APIs.

maintenance status npm version build status

Installation

$ npm install co-authy

To use co-authy you must be running node 0.11.9 or higher for generator support and node must be ran with the --harmony flag.

API

AuthyClient(apiKey, options)

Initialize a new Authy Client.

  • apiKey
  • options (Optional)
    • host Defaults to production endpoint (https://api.authy.com).

registerUser(email, cellphone, code)

Enable two-factor authentication on a user. You should store the returned authy_id in your database for subsequent calls.

The code can be one of the following:

  • An ISO 3166-1 alpha-2 code (e.g. PT) (recommended);
  • A valid country calling code (e.g. 351);

The library automatically converts conforming country codes to the corresponding country calling code. For instance, if the code passed is PT, then the calling code will be set to 351 without requiring extra work from the developer. Defaults to US (1) if omitted.

The output that is sent to Authy is destructured by removing the international plus sign prefix and respective country calling code from the E164 format. Example:

  • Function Input:
    • cellphone: 915 555-555
    • code: PT
  • Internal E164 representation:
    • +351915555555
  • Output to Authy API:
    • cellphone: 915555555
    • country_code: 351

Country metadata returned by lib/countries (for native name and translations, among other things) is sourced from the awesome countries project by @mdledoze.

verifyToken(authyId, token, options)

Verify a token entered by the user. Enable the force parameter to verify the token regardless of the user login status.

The token format is verified through an TOTP token validator.

requestSms(authyId, options)

Request an SMS with a token for users that don't own a smartphone. If the Authy app is in use by the user, this request is ignored and a push notification is sent instead. Pass force to send an SMS regardless of this. You can also use the shortcode option to send the SMS using short code (available in US and Canada).

Available options: ['force', 'shortcode']

requestCall(authyId, options)

Request a call with a token for users that don't own a smartphone or are having trouble with SMS. If the Authy app is in use by the user, this request is ignored. Pass force to call the user regardless of this.

deleteUser(authyId)

Delete an user from the application.

getUserStatus(authyId)

Retrieve an user status.

registerActivity(authyId, type, ip, data)

Register an user activity.

getApplicationDetails()

Retrieves the application details.

getApplicationStatistics()

Retrieves the application statistics.

Usage

A basic example on how to register a user using the Authy client via the sandbox API. To use this example, you should register on Authy and then pass your own API secret key via the AUTHY_KEY environment variable.

var assert = require('assert');
var client = require('co-authy')(process.env.AUTHY_KEY, 'http://sandbox-api.authy.com');
var co = require('co');

co(function *() {
  var response = yield client.registerUser('[email protected]', '912345678', 'PT');

  assert('number' === typeof response.user.id);

  console.log('AuthyID:', response.user.id);
})();
$ AUTHY_KEY=<secret key> node --harmony index.js

How phone validation works

Authy documentation is not clear on how their phone number validation works, but if their js version is any indication, they use a generic regular expression that matches almost all possible phone combinations.

In general, this approach is fine for most applications, but sometimes a more precise control is needed to avoid programmer errors and also to provide a better UX to users. For instance, if a number is invalid for a certain region but apparently is in the correct format, Authy will report a success status when requesting an SMS, even though the message will never reach the destination. This will leave the end-user wondering why your service does not work properly.

This library uses the full-featured phone number validation library libphonenumber created by Google to power everything phone number-related on its Android 4.0 platform. There is also strong evidence that the same code is used to enable the phone validation check on their 2-Step Verification process. While validating phone numbers is a daunting task with many quirks and intricacies, the line of thinking is that if it works for Google, it should work for us too.

By using such a comprehensive library, one can provide out-of-box true phone number validation including region validation, i.e., making sure a phone number is valid for a specific region. This is common in the North American Numbering Plan (NANP), where a number like +1 408-550-3542 is valid in the United States but not in Canada, even though they share the same country calling code (+1).

Another common scenario is using a number with an International Dialing Prefix (IDD), e.g. 00 in most countries, 011 in the US or 0011 in Australia (and the list goes on) so that the final result is something like 0011 1 408-550-3542 to call a US phone from Australia - while this number is valid in the sense that it can be called from Australia, it is not considered valid for that region because the number is, in fact, a US-based one. This is interesting because by passing this number to #registerUser with an ISO 3166-1 alpha-2 of US, a validation error will occur. If you'd like to disable this check, omit the code as the last parameter and let the library deduce the country code from the phone number input (US in this case, the IDD is just an artifact).

To take advantage of all the validation features, you should pass an ISO 3166-1 alpha-2 code to #registerUser instead of a country calling code (e.g. 351), because there are situations where a country calling code matches multiple countries and validation becomes a mess. When there is a 1:1 match, validation is performed by comparing the country calling codes (e.g. 1 !== 351), otherwise the test is skipped.

To put it simply, avoid using country calling codes and use country codes as the source for country metadata instead.

Non-geographical entities

While non-geographical numbers (e.g. 800, 881, 882, etc.) are supported by this client implementation, they are not exposed on the list generated by lib/countries, which is more suited for UI presentation and validation (e.g. country selection dropdown). Again, Authy is not clear about which non-geographical numbers are supported, although +882 is listed on their official js client, so deal with care.

Tests

All public method are unit tested using nock for mocked responses.

$ npm test

If you wish to run the tests by hitting the actual URLs, you may disable nock entirely and pass your own API secret key via the AUTHY_KEY environment variable. The sandbox API is often reset which means tests may fail when running against the actual sandbox API endpoints.

$ NOCK_OFF=true AUTHY_KEY=<secret key> npm test
