EngineeringEmotion
The Syntax of Emotion
Framework builds product. Product generates data. Data drives research. One pipeline, no seams. Everything feeds everything.
WHO WE ARE
Builder's Perspective:
HUA Labs builds the full stack. Framework, product, research — every layer, in-house, connected.
Not a wrapper. Not a template. 16 packages, 4 production apps, agent-native documentation, AI workflow automation. Built to scale with machines, not just people.
Depth over breadth.
WHAT WE BUILD
1. FRAMEWORK & SDK
Component Library: 100+ production React components. Built from scratch, built to ship. Dark mode, accessibility — standard.
Motion System: 41 animation hooks. Scroll, parallax, magnetic. Declarative API, zero layout shift.
i18n Framework: SSR, namespaces, type-safe translations. A multilingual system that tolerates zero flicker.
2. EMOTION
PRODUCTS
Sum Diary: Not your typical AI diary. A space where writing becomes knowing.
Contextual Analysis: Not a mood score. 'A quiet evening alone' and 'being left alone' are different. It reads the difference.
3. OPEN SOURCE
Framework, Open: 12 packages on npm @hua-labs. Components, hooks, motion, i18n — all open source. Take them.
Built With HUA: This site, Sum Diary, the docs — all built on HUA. Fast iteration? That's our survival strategy.
HOW WE OPERATE
Build the framework. Components, hooks, utilities — from scratch. Agent-ready docs, 13 AI workflow skills, automated context generation. An ecosystem built for the AI era.
Ship the product. A framework that exists for the product. We build what we need and use it ourselves.
Research the impact. Real users, refined emotion data. How can AI safely understand how people feel — we study it, we publish it.
