Example Tauri v1 app using Python sidecar

A native app built with Tauri v1 that spawns a Python sub-process (sidecar) which starts a FastAPI server.

Introduction

This example app uses Next.js as the frontend and Python (FastAPI) as the backend. Tauri is a Rust framework that orchestrates the frontend and backend(s) into a native app experience.

How It Works

Tauri takes your frontend UI written in html/javascript and displays it in a native webview. This makes the resulting file size smaller since it does not need to include a web browser.

Getting Started

Dependencies

Install dependencies for javascript:

pnpm install

To install python dependencies listed in requirements.txt:

pnpm dev-reqs

In case you dont have PyInstaller installed:

pip install -U pyinstaller

Run

To run the app in development mode with hot-reload (js):

pnpm tauri dev

Build

Compile python sidecar

Run this at least once before running pnpm tauri dev and each time you make changes to your python code. This command is also called by pnpm tauri build:

pnpm build:fastapi

Build app for production:

pnpm tauri build

This creates an installer located here:

• <project-dir>\src-tauri\target\release\bundle\nsis
