nexy 2.1.1

The Modern Fullstack Python Meta-Framework: Build high-performance web apps .

Nexy

Nexy is a full-stack Python meta-framework that bridges FastAPI backends with Vite-powered frontends (React, Vue, Svelte, Solid, Preact). Sub-second startup, sub-100ms HMR.

Quick start

uvx nexy new
cd my-project
nexy dev

No pip install needed. uvx runs Nexy directly — your project gets its own isolated environment.

The .nexy format

One file. Python logic, Jinja2 template, optional interactive islands.

---
title : prop[str] = "Dashboard"
from "@/components/Chart.tsx" import Chart
---

<h1>{{ title }}</h1>
<Chart data="{{ api_data }}" />

• --- blocks: Python — props, imports, logic
• Body: Jinja2 — server-rendered HTML
• <script>: JavaScript/TypeScript — client interactivity via Vite

Routing

Pattern	URL
index.nexy	/
about.mdx	/about
blog/[slug].nexy	/blog/:slug
api/users.py	/api/users

File-based for small projects, module-based (NestJS-style) for enterprise.

Supported frontends

React, Vue, Svelte, Solid, Preact — or none for vanilla SSR.
