You can run external binaries in a Tauri app by configuring them as sidecars in the tauri.conf.json file under bundle.externalBin, then using Rust or JavaScript APIs to spawn and manage the process lifecycle.

A sidecar in Tauri is an external binary embedded within your application to extend functionality, allowing you to run auxiliary processes like data processors or API servers without bundling heavy runtimes into the main app bundle.

You configure external binaries in tauri.conf.json under the bundle.externalBin setting, ensuring you apply platform-specific binary naming conventions so Tauri can correctly locate and spawn the sidecar process on different operating systems.

Yes, you can manage long-running background services with Tauri sidecars by using the Rust and JavaScript APIs to spawn the external binary and handle its lifecycle for continuous auxiliary tasks like local API servers or language runtimes.

Yes, spawning sidecars in Tauri requires platform-specific binary naming conventions to ensure the cross-platform desktop app can correctly identify and execute the external binaries across different operating system environments.

Using a Tauri sidecar allows you to execute auxiliary processes like data processors without bundling heavy runtimes into the main application, simplifying cross-platform execution and keeping the core app bundle lightweight.
