fastapi-vue 0.8.3

Serves Vue assets on a FastAPI app. Use fastapi-vue-setup tool to add Vue build to your package.

fastapi-vue

Implements Single-Page-App serving at site root with FastAPI, that the standard StaticFiles module cannot handle. This also caches and zstd compresses the files for lightning-fast operation. This is primarily meant for use with Vue frontend, but technically can host any static files in a similar manner.

Installation

Script fastapi-vue-setup should normally be used to convert or create a project with connection between FastAPI and Vue. The target project will depend on this package to serve its static files.

uvx fastapi-vue-setup --help

Refer to instructions below for further configuration.

Usage

from contextlib import asynccontextmanager
from fastapi import FastAPI
from fastapi_vue import Frontend

frontend = Frontend(
    Path(__file__).with_name("frontend-build"),
    spa=True,
    cached=["/assets/"],
)

@asynccontextmanager
async def lifespan(app: FastAPI):
    await frontend.load()
    yield

app = FastAPI(lifespan=lifespan)

# Add API routes here...

# Final catch-all route for frontend files (keep at end of file)
frontend.route(app, "/")

Configuration

• directory: Path to static files directory
• spa: Enable SPA mode (serve index.html for unknown routes)
• cached: Path prefixes for immutable cache headers (browser won't check for changes)
• favicon: Path to serve at /favicon.ico (e.g., "/logo.png" will be served as image/png)
• zstdlevel: Compression level (default: 18)
