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 🙏

micro-problems

NPM Travis Codecov Greenkeeper badge David David Dev

A companion library to micro which helps in responding to requests with application/json+problem

Installing

# npm
npm install -s micro-problems

# yarn
yarn add micro-problems

Usage

// out-of-credit.js
import declareProblem from "micro-problems";

// First off, you want to declare the type of problem your application could encounter.
const { handler, Problem, decorator } = declareProblem({
  type: "https://example.com/api/probs/out-of-credit",
  status: 403,
  title: "You do not have enough credit.",
  detail:
    "Your current balance is lower than the cost of what you are trying to purchase."
});

export { handler, Problem, decorator };

In the rest of this example, I leave it up to the reader to pick their preferred method of routing requests. Assume in this example that any file in the api folder would be routed as the corresponding route (minus the file extension).

// api/probs/out-of-credit.js

import { handler } from "../../out-of-credit";

// If you are the one serving the URI connected to the problem, you can use `handler` to respond to it.
export default handler;
// api/purchases.js

import {
  Problem as OutOfCreditProblem,
  decorator as withOutOfCreditProblem
} from "../out-of-credit";

// A handler which could encounter the problem, should use a combination of the Problem and decorator
export default withOutOfCreditProblem(async (req, res) => {
  const purchase = await json(req);
  const account = await determineAccount(req);
  if (account.credit < purchase.cost) {
    const notification = await account.addFailedPurchaseNotification(purchase)
    throw new OutOfCreditProblem(
      `Your current balance is ${account.credit}, but that costs ${purchase.cose}.`,
      {
        balance: account.credit,
        accounts: [account.uri, purchase.seller.uri]
      },
      notification.uri
    );
  }
});
