HMPL – Small Template Language for Rendering UI from Server to Client

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.

🐜 Small template language for displaying UI from server to client. It is based on customizable requests sent to the server via fetch and processed into ready-made HTML. Reduce the size of js files and create interface like on a framework!

In the maker’s words, at launch

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…

  htmgo - build simple and scalable systems with golang + htmx2024 · htmgo.dev · ▲166

  Hey all, I just wanted to share a project I've been working on for the past month. After years of heavy frameworks, I really like the idea of using htmx, but it’s a little too low level for me and needs a thin layer above it to facilitate things like components, better syntax with complex JS inside of an attribute, etc To try and solve this problem with a very minimal stack (golang + htmx) that I've been really enjoying, I'm building this project to cater to my needs and was thinking it would be useful for other developers.

  I made a HTMX Playground 100% in the browser2024 · lassebomh.github.io · ▲482

  I recently dug up an old project in an attempt to improve on it. It's a code sandbox for playing around with HTMX in the browser, that runs a mock server within the sandbox iframe. The server "framework" is loosely based on Django, so if you're familiar with Django, you'll immediately understand what's going on. I recommend clicking through the examples. Github repo: https://github.com/lassebomh/htmx-playground Probably my favorite part is the lack of HTMX specific code. It's designed to mimic the client and server, but really nothing else. In principle, this means that…

  Mizu.js – Lightweight HTML templating library for any-side rendering2024 · mizu.sh · ▲225

  Hey HN, I'd like to share a fun project I've been working on: mizu.js. It's a js library that add functional attributes support into your html, designed to be a simple and flexible alternative to fully-fledged web frameworks (such as Vue, React, and Angular), while offering more capabilities than other lightweight options (like Alpine.js and htmx). As it's written using modern ES features and due to its isomorphic nature, it can be run in both browsers and runtimes (Node, Deno, Bun) without any changes. This makes it ideal for client-side and server-side rendering, as well as static site…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Kitten TTS – 25MB CPU-Only, Open-Source TTS Model▲1,003

  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…
