THE AI-NATIVE LANGUAGE
One .nyx file compiles to a full-stack app with database, auth, and API. No webpack. No config files. No node_modules. Just code.
FULL-STACK BLOG · ONE FILE
table posts { title text required, body text }
security { login email password, protect /api/posts }
preset card { bg #1a1a2e, r 12px, p 2rem }
page / {
h1 "My Blog"
form /api/posts auth { input title, submit "Post" }
data posts = get /api/posts auth
each posts -> div preset=card { h3 .title, p .body }
}
→ SQLite DB + JWT auth + CRUD API + reactive UI. Zero config.

FEATURES
One language. One file. Full-stack.
Milliseconds. No webpack, no bundler, no waiting. Write, save, see. The entire compiler is a single TypeScript file.
Define tables in NyxCode. SQLite with WAL mode, auto-migrations, and auto-generated CRUD API. Zero SQL.
security { login email password, protect /api/posts }. JWT, bcrypt, rate limiting, middleware — all generated.
bg, r, p, fs, fw, c, m, d — plus layout attrs like flex=col center grid=3. Write CSS in shorthand, compile to real CSS.
form /api/posts auth { input title, submit 'Post', success -> reload }. Validation, auth headers, error handling — built in.
Reusable components with props, slots, and default values. Style presets for consistent design. Import across files.
SSE-based dev server. Edit your .nyx file, see changes instantly. No page refresh, no state loss.
Define colors and fonts once. Auto-apply to all elements. Change your entire design by editing 3 lines.
Compiles to clean HTML, CSS, and vanilla JS. Zero runtime dependencies. Deploy anywhere — Netlify, Vercel, Caddy, nginx.
