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.


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 🙏

a top level exception handle package





All Contributors Build Status codecov npm GitHub license Maintenance


This package was created to add a general way to handle exception for express application with the expectation to make it simpler to handle all possible requests.


add it to your project with npm install express-exception-handler or yarn add express-exception-handler


there are 2 different ways to integrate the main functionality of this package, either by adding the handle that gets injected to the router framework

var exceptionHandler = require('express-exception-handler')
const app = require('express')()

or by wraping manually the routes

var wrap = require('express-exception-handler').wrap'/', wrap(async (req, res) => {

it also integrates an extended class from Error that contains a message and a status that can be used to pass diferent information to the error handle

var httpError = require('express-exception-handler').exception'/', async (req, res) => {
    throw new HttpError('Great Message', 400, "{Response: awesome}")

last but not least it also contains a middleware that can be added directly to express that handles the previous named errors.

var middleware = require('express-exception-handler').middleware
const app = require('express')()


The handle and the wrap function allow configuration parameters to be passed. The default is:

  nextOnce: true,
  defaultJsonResponse: false,
  • nextOnce: makes sure next can only be called once
  • defaultJsonResponse: runs res.json by default when the internally returned value is an object.
