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

exchangerate.host API

This is an JavaScript/TypeScript SDK for the exchangerate.host. The API responses are based on official API documentation

Requirements

Because this SDK uses fetch both in Node and the Browser, and ESM, we require the following:

  • Node 18.0.0 or higher
  • A modern, version infinite, browser

The package contains both an ESM and CommonJS build, so you can use it in both Node and the Browser.

Running the example app

First install the dependencies:

yarn install

To run the app:

yarn run start

Creating a client instance

Creating an instance of the SDK is easy

import {ExchangerateHostApi} from '@checksanity/exchangerate-host-api';

const api = ExchangerateHostApi.create();

Each of these factory methods will return a ExchangerateHostApi instance, which you can use to make requests to the exchangerate.host API.

const result = await api.getLatest();
console.log(result);

Extensibility

All of the constructors support a configuration object that lets you override the default behavior of the SDK.

const defaultConfig: SdkConfiguration = {
    fetch: (req: RequestInfo | URL, init: RequestInit | undefined) =>
        fetch(req, init),
    url: '<your custom url>',
};

As a general rule, this options should be overridden when you create your instance of the client, and you probably won't have to change most of them unless you have some very specific requirements.

You can provide the options like this, to any of the constructors or static initialization methods:

const opts = {
    fetch: (req, init) => {
        console.log("Fire custom fetch first");
        return fetch(req, init);
    }
}

const sdk = ExchangerateHostApi.create(opts);

All the below examples are in TypeScript, but the same method signatures all apply to JavaScript - just without the Type information.

Running the tests

You can run the tests with yarn run test.
