BDC – Ergonomic, sub 1KiB virtual DOM library
BDC is a simple library for updating the DOM to match a javascript description. Does not require JSX or a compilation step. clobber( document.body, h("marquee", [ h("span", {"style": "font-weight: bold"}, "Hello"), ", ", h("blink", "world"), "!", ]), ); Very fast to first render, moderately slow on subsequent updates. Prompted by the post on millionjs, which compiles user code to hit the same outrageously small size target.
In plain words
BDC is a lightweight virtual DOM library under 1 kilobyte that updates the DOM based on JavaScript descriptions without requiring JSX or compilation. Developers write code using simple function calls to create and modify HTML elements. The library prioritizes extremely small file size and fast initial rendering, though subsequent updates are slower. It's designed for developers seeking minimal dependencies and straightforward DOM manipulation without build tools.

Hello, HN - I wanted to share this puzzle game I made during my vacation. I'm rather fond of the pipes puzzle where your goal is to restore a scrambled network of connections by rotating tiles. It's usually played on a grid of squares and this all started when I decided to make a programmatic solver for that kind of puzzle. Then I realized that with some minor changes the solver could generate new puzzle instances. I thought about what kind of puzzle to make and someone suggested a hexagonal grid. Adapting the generator wasn't too hard but then I had to create a way to play this variant. So…

We're building Parsnip to create a "tech tree" of cooking skills that allows anyone to level up on the building blocks of cooking knowledge while tracking their progress over time. It took us a few iterations to figure out the right product; here's the story of our latest pivot: [https://parsnip.substack.com/p/a-new-hope] The goal is to create a personalized way to learn any recipe on the Internet, then use this as a springboard to help home cooks of all levels solve the problem of repeated meal planning in a 10x better way:…
