A React and Next.js UI Toolkit for LLMs
Hey HN, I wanted to share a UI toolkit project I’ve been working on recently, born out of how difficult I found it to build a great UX on top of LLMs, and keep application state in sync. I’ve built: - A React/JS front-end library for conversational interfaces, which makes it super easy to bootstrap AI assistants and ChatGPT style UX: https://github.com/nlkitai/nlux - A set of adapters that simplify integration with AI backends such as LangServe and HuggingFace The library is highly configurable, easy to theme, supports markdown streaming (that was tough to get…

In plain words
This React and Next.js UI toolkit helps developers build conversational interfaces and AI assistants. It provides a front-end library for chat-based UX and adapters for connecting to AI backends like LangServe and HuggingFace. The toolkit supports markdown streaming, custom component rendering, and theming, working with React, Next.js, and plain JavaScript. It's designed with modular architecture and zero dependencies.

ai-hooks – tiny useful AI tools for react2025 · ai-hooks.dev · ▲5Hi! My name is David and I wanted to show you a react (and solidjs) library I've built over the last months. The intention behind it is, that there are some actually useful use cases for AI on the frontend that are largely unexploited still. LLMs are particularly good at extracting structured information from unstructured text and thats really useful for any types of forms - which can be multimodal. Setting up server side logic for AI usage can take time. Streaming data to the frontend and parsing it there to make it usable can be frustrating. Imho thats one of the reasons why people…
- AJA JavaScript UI library for imperative JSX2024 · npmjs.com · ▲41
I've been building a web UI library for a side project of mine. I thought it might be useful to others, so I'm releasing it as open source. To put it simply, I realized that most of my pain points with React come from its declarative model ui=f(state). So I'm trying something that I'm calling "imperative JSX." Instead of treating JSX as the source of truth for your UI, it essentially becomes a query interface for DOM manipulation. I first had the idea for it a few months ago, and only began writing it in earnest last week, so it's extremely early and nowhere near production-ready. Still, I'd…
