I have built series of canvas libraries using Typescript, render engine, layout and CSS support.

The story is that I have spent decade writing a JavaScript UI library, I was hired during early days of jQuery movement, pivoted several times (html + images, html + css, flat html + css, canvas, canvas + webgl) however end up with unused tools and UI kit, few years later, during 2017 I have decided to rewrite some tools using Typescript and release as GPL2 (which I should change to LGPL2) and changed career.

I was dissatisfied with the available fixture/test data generation tooling for Obection.js and Knex, so I ported factory_bot from Ruby to Typescript. I’ve called it Fixture Riveter [0]. It’s more verbose than the other similar tools (factory_girl for javascript, Fishery for typescript), but it’s extremely versatile and supports factory_bot’s full api.

I was building a touchscreen music-production app for Windows, and I wanted it to have a phone/tablet style interface. It would have a stack of modal popup Views that the user could tap (or click) off of to close the top View and go back down. I ended up splitting the UI system off into a separate library and kept working on it. It now has DI (with scoping) and some other features. I've since used it for a few other…

Pretty neat. Is the Music app written somewhere ?

Also question to the room, is DI really worth it ? All that complexity to switch out sub-classes . A clean design but in practice it just feels like too much work for the benefit.

A Python program to make an embeddable search engine for a static website: https://github.com/joe-crawford/Static-Site-Search It indexes the site and generates search functionality in JavaScript (the index is just a static JSON file) that can be uploaded wherever JS/HTML/etc. files can be uploaded.

That’s pretty clever, I guess that for most personal blogs it will be more that sufficient.

Cheers, yes that was the idea!

I looked for a while to find something similar. I'm sure it must already be implemented out there, but to answer the question in the original post about why build something, I couldn't find an easily downloadable "tool" for doing it when I looked (2019) and it was simple enough to be "fun".

https://github.com/cnizzardini/cakephp-swagger-bake which builds out openapi from your cakephp applications meta data. One of many projects I took up to occupy myself during covid lockdowns.

I wasn't satisfied with writing the YAML or annotations manually.

I made Smocker[1]. It's a mock server we use extensively with my coworkers because we develop Go HTTP "micro" services and most of the tests we write are integration/component tests. We needed a way to mock the external services to test our service in an isolated way. Before that we used http-mock-server but it came short in a lot of ways: JSON config (very bad when you need to configure it to return JSON payloads), bad performances (our tests made it crash routinely), big memory and space footprint (a bit annoying for our CI and for our test machines). So we made Smocker to fix these issues and add more useful features. It does less than http-mock-server but is more focused IMO.

I wrote a cooperative multitasking system for Turbo Pascal because I needed to be able to stream data through a series of text pipes and it was easier than faking it with a bunch of temporary files. I also wrote a series of data entry routines to allow the quick creation of database editing programs. I haven't open sourced them because I doubt anyone would care about those old MS-DOS/TP7 tools now, and I'm not up for…

Maybe not a huge audience but I bet the people needing them would be hugely grateful. I use a couple old tools that I gladly contribute ( money ) to because despite being old they work great and there is no alternative.

I wrote a library for animating image backgrounds on the web using After Effects style filters and transitions: https://aeroheim.github.io/midori/ It's basically a post-processing pipeline implemented with Three.js and WebGL using a few shaders that I wrote. I created it primarily because I needed it for one of my current projects, so the use case is fairly niche and mostly only relevant for stuff like creative codin…

This is really cool! I’ve never seen a slideshow look that nice

I've built several extensions to vscode. My best one has to be a tool to help you upgrade dependencies in your package.json: https://github.com/pgsandstrom/package-json-upgrade I just felt that other extensions lacked polish. The UX wasn't very good, or they didn't read all npm config properly.

Wow I love it!
