Q.js – Smaller than React/Vue, yet more powerful (40KB gzipped)

In plain words

Q.js is a lightweight JavaScript framework built from a production platform used since 2011 to power social applications. At 40KB gzipped, it is smaller than React or Vue while offering comparable features. The framework lazy-loads components as they appear on screen and comes in a minimal version designed to be dropped into existing websites. Developers can start with Q.minimal.js and swap it for the full Q.js library if additional features are needed later.

All-In-One Front-End Web Framework from Qbix, alternative to jQuery, Angular, Vue, Ember etc. - Qbix/Q.js

In the maker’s words, at launch

Q.js is a lightweight JS framework that I recently distilled from our in-house Qbix platform that I’ve been building since 2011. It powers many of our social apps, which have all the features of Facebook, LinkedIn, X, etc. We’re not a big company like Google or Meta, so we never released it publicly. Now I’d like to…

  Minimal, no-JS web forum software2022 · github.com · ▲392

  Hello HN! I've found my SQL knowledge to be lacking, so I made a project that uses SQLite as a backend. As it is intended for self-hosting I aim to make it easy to set up and maintain. Getting it up & running takes no more than a few commands (bar setting up a proxy such as nginx, which is out of scope). I've set up a "demo" site at https://forum.agreper.com/ if you want to try out the UI.

  Swap.js – a JavaScript micro-framework (HTML fragments over the wire)2023 · github.com · ▲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…

  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…
