HMPL – Small Template Language for Rendering UI from Server to Client
Hi HN! Together with contributors, we've been making a small template language for a year now, which, in our opinion, can replace HTMX and Alpine.js. It is a mix between EJS and Handlebars, that is, you can make a request with a familiar syntax to the server in HTML right in the markup. Requests are made via fetch and are configured via javascript almost entirely, which is what is needed today to work with the server. The very essence of the template language comes down to minimizing the size of the bundle of the original web application by moving the components to the server and then…
In plain words
HMPL is a lightweight template language designed to render UI components from server to client, combining syntax elements from EJS and Handlebars. It enables developers to make server requests directly in HTML markup using familiar syntax, with fetch-based communication configured primarily through JavaScript. The tool targets developers seeking to reduce client-side bundle sizes by moving components to the server, allowing the client to progressively render elements as needed rather than loading a complete framework upfront.

Hi HN! Together with contributors, we've been making a small template language for a year now, which, in our opinion, can replace HTMX and Alpine.js. It is a mix between EJS and Handlebars, that is, you can make a request with a familiar syntax to the server in HTML right in the markup. Requests are made via fetch and are configured via javascript almost entirely, which is what is needed today to work with the server. The very essence of the template language comes down to minimizing the size of the bundle of the original web application by moving the components to the server and then storing them there. Thus, on the client we get a framework, where we insert components from the server brick by brick. We showed this template language a long time ago, but it was not so mature then, so people had a lot of questions: https://news.ycombinator.com/item?id=41204552 Thank you very much to everyone for your attention! Please tell me what you think about the project? It will be interesting to know!

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript.
