Command Line Interface (CLI)

GitHub npm crates.io

API Reference

Tauri enables your app to have a CLI through clap, a robust command line argument parser. With a simple CLI definition in your tauri.conf.json file, you can define your interface and read its argument matches map on JavaScript and/or Rust.

Supported Platforms

This plugin requires a Rust version of at least 1.77.2

Platform	Level	Notes
windows
linux
macos
android
ios

• Windows
  • Due to an OS limitation, production apps are not be able to write text back to the calling console by default. Please check out tauri#8305 for a workaround.

Setup

Install the CLI plugin to get started.

Automatic

Use your project’s package manager to add the dependency:

npm

npm run tauri add cli

yarn

yarn run tauri add cli

pnpm

pnpm tauri add cli

deno

deno task tauri add cli

bun

bun tauri add cli

cargo

cargo tauri add cli

Manual

1. Run the following command in the src-tauri folder to add the plugin to the project’s dependencies in Cargo.toml:

   cargo add tauri-plugin-cli --target 'cfg(any(target_os = "macos", windows, target_os = "linux"))'

   2. Modify lib.rs to initialize the plugin:

   src-tauri/src/lib.rs

   #[cfg_attr(mobile, tauri::mobile_entry_point)]
   pub fn run() {
       tauri::Builder::default()
           .setup(|app| {
               #[cfg(desktop)]
               app.handle().plugin(tauri_plugin_cli::init());
               Ok(())
           })
           .run(tauri::generate_context!())
           .expect("error while running tauri application");
   }

   3. Install the JavaScript Guest bindings using your preferred JavaScript package manager:
   npm

   npm install @tauri-apps/plugin-cli

   yarn

   yarn add @tauri-apps/plugin-cli

   pnpm

   pnpm add @tauri-apps/plugin-cli

   deno

   deno add npm:@tauri-apps/plugin-cli

   bun

   bun add @tauri-apps/plugin-cli

Base Configuration

Under tauri.conf.json, you have the following structure to configure the interface:

src-tauri/tauri.conf.json

{
  "plugins": {
    "cli": {
      "description": "Tauri CLI Plugin Example",
      "args": [
        {
          "short": "v",
          "name": "verbose",
          "description": "Verbosity level"
        }
      ],
      "subcommands": {
        "run": {
          "description": "Run the application",
          "args": [
            {
              "name": "debug",
              "description": "Run application in debug mode"
            },
            {
              "name": "release",
              "description": "Run application in release mode"
            }
          ]
        }
      }
    }
  }
}

Note

All JSON configurations here are just samples, many other fields have been omitted for the sake of clarity.

Adding Arguments

The args array represents the list of arguments accepted by its command or subcommand.

Positional Arguments

A positional argument is identified by its position in the list of arguments. With the following configuration:

src-tauri/tauri.conf.json

{
  "args": [
    {
      "name": "source",
      "index": 1,
      "takesValue": true
    },
    {
      "name": "destination",
      "index": 2,
      "takesValue": true
    }
  ]
}

Users can run your app as ./app tauri.txt dest.txt and the arg matches map will define source as "tauri.txt" and destination as "dest.txt".

Named Arguments

A named argument is a (key, value) pair where the key identifies the value. With the following configuration:

tauri-src/tauri.conf.json

{
  "args": [
    {
      "name": "type",
      "short": "t",
      "takesValue": true,
      "multiple": true,
      "possibleValues": ["foo", "bar"]
    }
  ]
}

Users can run your app as ./app --type foo bar, ./app -t foo -t bar or ./app --type=foo,bar and the arg matches map will define type as ["foo", "bar"].

Flag Arguments

A flag argument is a standalone key whose presence or absence provides information to your application. With the following configuration:

tauri-src/tauri.conf.json

{
  "args": [
    {
      "name": "verbose",
      "short": "v"
    }
  ]
}

Users can run your app as ./app -v -v -v, ./app --verbose --verbose --verbose or ./app -vvv and the arg matches map will define verbose as true, with occurrences = 3.

Subcommands

Some CLI applications have additional interfaces as subcommands. For instance, the git CLI has git branch, git commit and git push. You can define additional nested interfaces with the subcommands array:

tauri-src/tauri.conf.json

{
  "cli": {
    ...
    "subcommands": {
      "branch": {
        "args": []
      },
      "push": {
        "args": []
      }
    }
  }
}

Its configuration is the same as the root application configuration, with the description, longDescription, args, etc.

Usage

The CLI plugin is available in both JavaScript and Rust.

JavaScript

import { getMatches } from '@tauri-apps/plugin-cli';
// when using `"withGlobalTauri": true`, you may use
// const { getMatches } = window.__TAURI__.cli;

const matches = await getMatches();
if (matches.subcommand?.name === 'run') {
  // `./your-app run $ARGS` was executed
  const args = matches.subcommand.matches.args;
  if (args.debug?.value === true) {
    // `./your-app run --debug` was executed
  }
  if (args.release?.value === true) {
    // `./your-app run --release` was executed
  }
}

Rust

src-tauri/src/lib.rs

use tauri_plugin_cli::CliExt;

#[cfg_attr(mobile, tauri::mobile_entry_point)]
pub fn run() {
   tauri::Builder::default()
       .plugin(tauri_plugin_cli::init())
       .setup(|app| {
           match app.cli().matches() {
               // `matches` here is a Struct with { args, subcommand }.
               // `args` is `HashMap<String, ArgData>` where `ArgData` is a struct with { value, occurrences }.
               // `subcommand` is `Option<Box<SubcommandMatches>>` where `SubcommandMatches` is a struct with { name, matches }.
               Ok(matches) => {
                   println!("{:?}", matches)
               }
               Err(_) => {}
           }
           Ok(())
       })
       .run(tauri::generate_context!())
       .expect("error while running tauri application");
}

Permissions

By default all potentially dangerous plugin commands and scopes are blocked and cannot be accessed. You must modify the permissions in your capabilities configuration to enable these.

See the Capabilities Overview for more information and the step by step guide to use plugin permissions.

src-tauri/capabilities/default.json

{
  "$schema": "../gen/schemas/desktop-schema.json",
  "identifier": "main-capability",
  "description": "Capability for the main window",
  "windows": ["main"],
  "permissions": ["cli:default"]
}

Default Permission

Allows reading the CLI matches

• allow-cli-matches

Permission Table

Identifier	Description
cli:allow-cli-matches	Enables the cli_matches command without any pre-configured scope.
cli:deny-cli-matches	Denies the cli_matches command without any pre-configured scope.
