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 🙏

MangaRock Image Decoder

Decode images from MangaRock's proprietary format

MangaRock has a nice API to work with, but obscures images by encoding them as bitwise xor'd .webp images. This codebase is a web microservice that decodes images into their native .webp format for easy consumption outside of MangaRock.

This microservice was built for the poketo library.

Usage

This package is available on npm, or as a microservice deployed to https://mri-image-decoder.now.sh. To use the microservice, pass the image's URL to the ?url query parameter like so:

https://mri-image-decoder.now.sh?url=https://f01.mrcdn.info/file/mrfiles/i/6/n/l/T3.3BZTN7p5.mri

This will return the image with the correct content type set, so you can simply load or use it like any other image URL:

<img src="https://mri-image-decoder.now.sh?url=https://f01.mrcdn.info/file/mrfiles/i/6/n/l/T3.3BZTN7p5.mri" />

JS API

To use this package from npm, install it:

npm install manga-rock-image-decoder

This package exports a single function, decode which accepts a .mri image buffer and returns a converted .webp buffer

const decode = require('manga-rock-image-decoder');

const webpImageBuffer = decode(mriImageBuffer);

You can use an image conversion tool, such as sharp, to convert the .webp image to
