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 🙏

Readme

Parsimmon

Authors: @jneen and @laughinghan

Maintainer: @wavebeem

Parsimmon is a small library for writing big parsers made up of lots of little parsers. The API is inspired by parsec and Promises/A+.

Parsimmon supports IE7 and newer browsers, along with Node.js. It can be used as a standard Node module through npm (named parsimmon), or directly in the browser through a script tag, where it exports a global variable called Parsimmon. To download the latest browser build, use the unpkg version. For more information on how to use unpkg, see the unpkg homepage.

Common Functions

Questions

Feel free to ask a question by filing a GitHub Issue. I'm happy to help point you in the right direction with the library, and hopefully improve the documentation so less people get confused in the future.

Contributing

Contributions are not just pull requests.

Issues clearly describing bugs or confusing parts of Parsimmon are welcome! Also, documentation enhancements and examples are very desirable.

Feeling overwhelmed about contributing? Open an issue about what you want to contribute and I'm happy to help you through to completion!

Performance

Thanks to @bd82 we have a good benchmark comparing Parsimmon CPU performance to several other parser libraries with a simple JSON parser example.

Fantasyland

Parsimmon is also compatible with fantasyland. It implements Semigroup, Apply, Applicative, Functor, Chain, and Monad.
