Sidecar (Embedding External Binaries)	Sidecar

import Alert from '@theme/Alert'

You may need to embed depending binaries in order to make your application work or to prevent users having to install additional dependencies (e.g. Node.js, Python, etc).

To bundle the binaries of your choice, you can add the externalBin property to the tauri namespace in your tauri.conf.json.

See more about tauri.conf.json configuration here.

externalBin expects a list of strings targeting binaries either with absolute or relative paths.

Here is a sample to illustrate the configuration, this is not a complete tauri.conf.json file:

{
  "tauri": {
    "bundle": {
      "externalBin": ["/absolute/path/to/bin1", "relative/path/to/bin2"]
    }
  }
}

This way, you may execute commands with Rust in your Tauri application.

Tauri provides some functions to handle standard cases (like loading platform specific binaries), such as:

• tauri::api::command::binary_command, which will append the current environment triplet to the input (useful for cross-environments). If you're creating your own binary, you'll have to provide a binary for each platform you're targeting by specifying the target triplets, e.g. "binaryname-x86_64-apple-darwin".

Target triplets can be found by executing the rustup target list command.

• tauri::api::command::relative_command that will relatively resolve the path to the binary.
