SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Embedding external binaries (sidecars) inside a Tauri application extends functionality without requiring users to install dependencies. This guide shows how to configure, name, and run sidecars from Rust and JavaScript.

Core Features & Use Cases

  • Register sidecars in tauri with bundle.externalBin and provide cross-platform binaries.
  • Use platform-specific naming (suffixes) to ensure correct executables on Linux, macOS, and Windows.
  • Execute sidecars from Rust via tauri_plugin_shell and from JavaScript via the plugin-shell, including long-running processes and argument passing.
  • Real-world use cases include bundling Python tools with PyInstaller, API servers, data processors, or language runtimes as sidecars.

Quick Start

Install and configure a sidecar in your Tauri app, then invoke it from Rust or JavaScript to execute the external binary.

Frequently Asked Questions about embedding-tauri-sidecars

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I embed and run sidecar binaries in a Tauri app?▼

To embed sidecar binaries in Tauri, register them under bundle.externalBin and invoke them using tauri-plugin-shell from either Rust or JavaScript to execute the external binary.

Why does my Tauri external binary fail to launch on different operating systems?▼

Tauri requires platform-specific binary naming with suffixes for Linux, macOS, and Windows. You must provide correctly suffixed executables under bundle.externalBin to ensure the correct binary runs on each OS.

Can I bundle a Python tool or API server inside a Tauri desktop application?▼

Yes, you can bundle Python tools packaged with PyInstaller or API servers as sidecars in cross-platform Tauri desktop apps, extending functionality without requiring users to install dependencies.

How do I execute a long-running sidecar process and pass arguments from JavaScript in Tauri?▼

You can execute long-running sidecar processes and pass arguments from JavaScript using the tauri-plugin-shell API, which handles invocation and communication with external binaries bundled in the Tauri app.

Do I need tauri-plugin-shell to run external binaries in Tauri?▼

Yes, tauri-plugin-shell is required to run external binaries in Tauri. It provides the necessary APIs to invoke sidecars from both Rust and JavaScript within your cross-platform desktop application.
