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
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:
- \
\src-tauri\target\release\bundle\nsis
