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 🙏

Easily manage cloudformation stacks in javascript





npm i @hydre/cfn


import { cfn, param } from '@hydre/cfn'

To print logs you'll need to add the DEBUG env variable with cfn*

DEBUG='cfn*' node my-app.js

Create an api instance (you can create as many as you want with different regions or keys)

const api = cfn(apiKey, secretKey, region)

// you can also use AWS_PROFILE env variable or AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY with a custom region
const api = cfn(...[, , region])
const api = cfn()

All functions return a promise

Validate a stack (resolve to true or false)

// the template as a JS object
// the optional name for debug logs purpose
.validate(template[, name])

Create or update a stack (resolve to void or throw an err)

// [, option] represent default params from the aws sdk when you either create or update a stack
// if you provide a StackName field in the option param it will override the name param
.createOrUpdate(name, template[, params][, options])

Delete a stack (resolve to void or throw an err)



import { cfn, param } from '@hydre/cfn'

const { AWS_KEY_FOO, AWS_SECRET_FOO } = process.env
const api = new cfn(AWS_KEY_FOO, AWS_SECRET_FOO, 'us-west-1')

const template = {
	AWSTemplateFormatVersion: '2010-09-09',
	Description: 'readme',
	Resources: []

void (async function() {
	await api.validate(template)

	await api.createOrUpdate('my-stack', template, [
		param('key', 'value'),
		param('key', 'value'),
		param('key', 'value'),
		param('key', 'value')

	await api.delete('my-stack')
