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 🙏

Usage

Installation

Using npm:

  • npm install @transferwise/approve-api-action-helpers

Using CDN and script tags:

  • <script src="https://unpkg.com/@transferwise/approve-api-action-helpers@latest/dist/main.js"></script>

Note that to use this library with Internet Explorer (11) fetch and Promise must be polyfilled. For example: https://polyfill-fastly.io/v3/polyfill.min.js?features=fetch%2CPromise. Comment out the script in the demo (demo/src/inex.html) to see it in action.

Consuming

This library exports a create function for SCA protected requests. It returns a request wrapper that can be used like a regular fetch request. Use it as follows:

import { create, Mode } from '@transferwise/approve-api-action-helpers';

const request = create({ mode: Mode.PRODUCTION });

const res = await request('https://my-backend-api.com/sca-protected-call', { method: 'GET', ... });

When the backend returns that SCA is required, it will run the user through an SCA flow and retry that request. Also, it will throw an error if you get a 4xx or 5xx response.

NB! make sure that your backend proxies 'x-2fa-approval' response header to the frontend and forwards it back to Wise when this library passes it back. Also please reflect the response status (403) back to the frontend.

Configuration options

| key | optional | default | alternatives | |------|----------|----------------------|--------------| | mode | yes | Mode.PRODUCTION | Mode.SANDBOX |

Demo

In /demo directory you'll find a simple demo of the flow.
