Litestar Vite

Litestar Vite connects the Litestar backend to a Vite toolchain. It supports SPA, Template, Inertia, and meta-framework workflows, and it can proxy Vite dev traffic through your ASGI port or run Vite directly.

Features

• One-port dev: proxies Vite HTTP + WS/HMR through Litestar by default; switch to two-port with VITE_PROXY_MODE=direct.
• Framework-mode support: use mode="framework" (alias mode="ssr") for Astro, Nuxt, and SvelteKit. Litestar proxies everything except your API routes.
• Production assets: reads the Vite manifest from public/manifest.json (configurable) and serves under asset_url.
• Type-safe frontends: optional OpenAPI/routes export plus @hey-api/openapi-ts via the Vite plugin.
• Inertia support: stable v2 protocol with session middleware, optional script-element bootstrap, and optional SSR.

Install

pip install litestar-vite
npm install litestar-vite-plugin

Quick Start

import os
from pathlib import Path
from litestar import Litestar
from litestar_vite import PathConfig, ViteConfig, VitePlugin

DEV_MODE = os.getenv("VITE_DEV_MODE", "true").lower() in ("true", "1", "yes")

app = Litestar(
    plugins=[VitePlugin(config=ViteConfig(
        dev_mode=DEV_MODE,
        paths=PathConfig(root=Path(__file__).parent),
    ))]
)

litestar assets init --template vue
litestar assets install
litestar run --reload

Common Commands

• litestar assets init --template <name>: scaffold a frontend or framework app
• litestar assets install: install frontend dependencies with the configured executor
• litestar assets build: build production assets
• litestar assets serve: run the frontend toolchain directly
• litestar assets generate-types: export OpenAPI, routes, and Inertia page-prop metadata
• litestar assets doctor: inspect and optionally repair config drift

Development

# Install Python, docs, and JS dependencies; build package artifacts
make install && make build

# Run an example app
uv run litestar --app-dir examples/vue-inertia assets install
uv run litestar --app-dir examples/vue-inertia run

Replace vue-inertia with any other example app: vue, react, svelte, react-inertia, htmx, angular, astro, nuxt, or sveltekit.

For Inertia script-element bootstrap, enable InertiaConfig(use_script_element=True) on the Python side and keep createInertiaApp({ defaults: { future: { useScriptElementForInitialPage: true } } }) aligned in the browser entry and SSR entry when ssr=True is enabled.
