24 alternatives to Next.js-like Python web framework, built for Htmx with FastAPI
It's very early days for the project, but I wanted to share it to see if there is interest. It is the final piece of the FastAPI server-side rendering stack I started building with FastHX and htmy (the two dependencies of this project besides FastAPI). Think of it as a more powerful and convenient alternative to tools like FastHTML, powered by FastAPI (without any modifications). I hope you'll like it.

I love Streamlit but have run into many situation where taking it from PoC to MVP state is insurmountable. With all the recent HN hype around htmx and sematic html / classless css I decided to build a Streamlit alternative using these on top of FastAPI. This has a couple advantages: 1) easier to extend when you move past PoC since the FastAPI app is exposed (allowing adding more routes) and hstream acts more like a typical web stack 2) with htmx and html (plus MVP.css) doing the heavy lifting the package is alot less complex and easier to reason about - and hopefully more performant…

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…

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.

Hello HN, I'm releasing Hyperdiv (https://hyperdiv.io), a framework for rapidly developing reactive browser UIs in Python, with immediate-mode syntax and using Shoelace (https://shoelace.style) as its built-in component system. This short coding video will give you a good idea of what it is: https://www.youtube.com/watch?v=4XJKfxaqvGE I wrote a brief article about the motivation and approach: https://hyperdiv.io/intro.html Hyperdiv doesn't aim to compete with serious full-stack frameworks. The core aim was to make it easy and fast to…

Hi everyone! I've been working on a web search interface for Python's documentation as a personal project, and I think it's ready for other people to use... Please give it a go (and join me in praying to the server gods): https://pythondocs.xyz/ Here's the tech stack for those interested: - Parser: Beautiful Soup + Mozilla Bleach - Database: in-memory SQLite (aiosqlite) + SQLAlchemy - Web server: FastAPI + Uvicorn + Jinja2 - Front end: Tailwind CSS + htmx + Alpine.js I have ideas for future improvements but hopefully the current version is useful to someone. Let me know what…

Hi HN! I created this lib in the need of a simple and tiny framework to easily do AJAX-style navigation / replacement of fragments in the page, in a web application. For people who don't want to use client-side-rendering and complex frameworks à la React, there are nowadays a few "HTML-over-the-wire" libraries, like HTMX, Unpoly or this super-tiny one Swap.js :) One other key thing is that no external tool is needed: no bundler, no webpack, no TypeScript compiler, no minification needed. Just write HTML, JS (+ your preferred server-side language: PHP, Python, etc.) and it works. The…

Source https://github.com/dashborg/hibiki | Interactive Tutorial https://playground.hibikihtml.com/tutorial/ I love JavaScript, but for many projects -- especially internal tools and prototypes -- setting up a full frontend JavaScript stack (npm, webpack, babel, create-react-app, redux) and all of their configuration files, folders, and scaffolding is overkill. Hibiki HTML incrementally plugs into any backend, using any template language (even static HTML files) with a single script include. It includes a built-in frontend data model, Vue.js-like…

We're excited to announce Lowdefy V4, a full-stack web framework built on top of Next.js that simplifies building web applications, internal tools, admin panels, BI dashboards, and CRUD apps using YAML or JSON configuration files. New in V4: Next.js: Lowdefy now runs on top of the Next.js framework. All of Auth.js: App auth is now handled by Auth.js supported providers, adapters and callbacks and events, easy to configure, but all of which can be customized. Plugin extensibility: Apps can now be extended with any npm or pnpm workspace plugins. Our story: We have developed a simple…

Hey HN, I’m Pierce. Today I’m open sourcing a beta of Mountaineer, an integrated framework for building webapps in React and Python. I’ve written a good 25+ webapps over the last few years in almost every major framework under the sun. Python and React remain my favorite. They let you get started quickly and grow to scale. But the developer experience of linking these two worlds remains less than optimal: — Sharing typehints and schemas across frontend and backend code — Scattered fetch() calls to template data and modify server objects — Server side rendering / gateway support — Error…

I built µJS because I wanted AJAX navigation without the verbosity of HTMX or the overhead of Turbo. It intercepts links and form submissions, fetches pages via AJAX, and swaps fragments of the DOM. Single tag, one call to `mu.init()`. No build step, no dependencies. Key features: patch mode (update multiple fragments in one request), SSE support, DOM morphing via idiomorph, View Transitions, prefetch on hover, polling, and full HTTP verb support on any element. At ~5KB gzipped, it's smaller than HTMX (16KB) and Turbo (25KB), and works with any backend: PHP, Python, Go, Ruby, whatever.…

Hi! I made a React compatibility library for a Virtual DOM library (https://github.com/aidenybai/million). The idea is to have much faster rendering (a compiler optimizes virtual DOM beforehand) while ensuring the same developer experience React provides. This is very, VERY early stage, so be prepared for weird bugs / plugin incompatibility / etc. If you have any suggestions, I'd be more than happy if you replied in a comment with it! You can spin up the demo here >> https://stackblitz.com/github/aidenybai/million-react-compat

Hey HN! I think _hyperscript is an insanely cool language, and while designed for simple front-end DOM interactions, I thought it would be a cool back-end scripting language as well. So, I slapped together a TODO app with a _hyperscript bootstrapping script based on the original repository's node-hyperscript example. My repo isn't clean, just something I worked out over a weekend to prove the concept, also an excuse to play with htmx. :) Please read the README, and let me know how, if anyone's interested, I can work in some of my tweaks to the original repository. I'm kind of a noob with…

Hey HN , My product is targeted at developers who want to save 20+ hours writing the same boilerplate code. *Next Inject* is a CLI that lets you configure services such as payments, authentication, and SEO with a single command. *Next Inject* is straight to the point; you get exactly what you pay for, i.e. run `next-inject add stripe` and voila, you can now accept payments from users. Now there are products like shipfa.st that solve this problem, but for *6x* the price, and *20x* more boilerplate to overwhelm developers. Additionally, each Next Inject plugin has an optimized docs page to…
