   Swap.js – a JavaScript micro-framework (HTML fragments over the wire)▲127

   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…

    Cami.js – A no build, web component based reactive framework▲113

    Hi Everyone! My main motivation for making this was that I wanted something as powerful as Svelte or React but I wanted no build steps, no JSON API, and I wanted something as close to vanilla js as much as possible. I'm mainly a backend developer, and I wanted to simply return html with some interactive islands when I need to (whose components get 'hydrated' with by backend language's templates). Some key ideas: • It's centered around light dom web components • Uses a "reactive element", which uses observables for fine-grained reactivity • Rendering is done through lit-html's tagged…

    µJS, a 5KB alternative to Htmx and Turbo with zero dependencies▲161

    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.…
