SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Embedding and executing external binaries (sidecars) inside Tauri apps lets you extend functionality without shipping heavy dependencies or requiring users to install tools.

Core Features & Use Cases

Configuration and registration of sidecars in tauri.conf.json under bundle.externalBin.
Cross-platform binary naming with target triples and platform-specific variants.
Rust and JavaScript APIs for spawning, arguments, streaming output, and lifecycle management.
Real-world scenario: ship a data processor as a sidecar and run it from the app to perform tasks without embedding large toolchains.

Quick Start

Install and configure a sample sidecar, then invoke it from Rust or JavaScript to observe output.

FAQPage Schema

How do I embed and run external binaries in Tauri apps?▼

You can embed external binaries in Tauri apps by configuring them in tauri.conf.json under bundle.externalBin, then spawning and managing them at runtime using tauri_plugin_shell APIs in Rust or JavaScript.

What is a Tauri sidecar and when do I need it?▼

A Tauri sidecar is an external binary embedded inside your app to extend functionality without shipping heavy dependencies. You need it when your app must run platform-specific tools or data processors without requiring users to install them separately.

How do I configure cross-platform binaries in tauri.conf.json?▼

Configure cross-platform binaries in tauri.conf.json under bundle.externalBin by naming your binaries with platform-specific target triples, ensuring Tauri bundles the correct variant for each operating system at runtime.

Can I spawn a sidecar from JavaScript and stream its output?▼

Yes, you can spawn sidecars from JavaScript using tauri_plugin_shell APIs, which support passing arguments, streaming output, and managing the binary lifecycle directly from your frontend code.

Does Tauri support running Rust or JavaScript code to monitor sidecar processes?▼

Yes, Tauri provides both Rust and JavaScript APIs via tauri_plugin_shell to spawn, monitor, and communicate with sidecar processes, handling arguments, streaming output, and safe lifecycle management at runtime.

What are the limitations of embedding external binaries in Tauri?▼

Limitations of embedding external binaries include the need for careful configuration in tauri.conf.json, strict platform-specific binary naming with target triples, and the requirement to manually manage safe process lifecycles via tauri_plugin_shell.
