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 🙏

Installation

$ npm install es-http-error

Usage

throw new HttpError(404) // 'Not Found' as a default message
throw new HttpError(401, 'Unauthorized') // Custom Error Message
throw new HttpError(statusCodes.notFound); // Using with enums

Supported http status codes are here.

Example

import HttpError, {statusCodes} from 'es-http-error'

main()
async function main (id) {
  try {
    // retrieve some data from API server
    const res = await fetch('/api/something/great')
    // check the response and throw an error if it's not ok
    if (!res.ok) throw new HttpError(res.status)
    
    // for example, render the view by lit-html
    const render(view(await res.json()), document.body)
  } catch (e) {
    if (e instanceof HttpError) {
      if (e.code === 401) logout() // check the code simply by number
      if (e.code === statusCodes.notFound) notFound() // or via statusCodes
    } else throw e
  }
}

i18n

import HttpError, {statusCodes} from 'es-http-error/langs/ja'

try {
  throw new HttpError(404)
} catch (e) {
  console.log(e.message) // translated message "未検出"
}

Supported languages are listed here.

Serverside Usage (on Node.js)

This library also provides a CommonJS vesion complementally.

Note: there's no support for i18n for CommonJS version.

const HttpError = require('es-http-error')
const {statusCodes} = HttpError

throw new HttpError(statusCodes.notFound)

Motivation

There're some prior arts like below, but I couldn't find the one for browsers. So I made it.

...etc.
