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 🙏

@cycle/callbags

Build codecov code style: prettier

This is the set of callbags that will most likely be used in the next version of Cycle.js. They are written in TypeScript and export ES modules to allow for tree shaking. Also, the implementation is specifically tailored to the Cycle.js use case, so all of them are push-only. Using them with sink or operators that try to pull the sources here will most likely lead to bugs und weird behavior.

Building

This project uses pnpm, other package managers might work, but only pnpm has a lockfile that pins dependencies. To build run:

pnpm install
pnpm run build

Implemented operators

Currently, the following set of operators is implemented, others might follow. Note that this repo is not designed to become the "official" home of callbags, so after a basic set is implemented it is very unlikely that further operators will be added. This is no problem in practise as all of the callbags here adhere to the spec, so you can easily mix and match them with any callbag operator out there.
