@tauri-apps/plugin-shell

Access the system shell. Allows you to spawn child processes and manage files and URLs using their default application.

Security

This API has a scope configuration that forces you to restrict the programs and arguments that can be used.

Restricting access to the `open` API

On the configuration object, open: true means that the open API can be used with any URL, as the argument is validated with the ^((mailto:\w+)|(tel:\w+)|(https?://\w+)).+ regex. You can change that regex by changing the boolean value to a string, e.g. open: ^https://github.com/.

Restricting access to the `Command` APIs

The plugin permissions object has a scope field that defines an array of CLIs that can be used. Each CLI is a configuration object { name: string, cmd: string, sidecar?: bool, args?: boolean | Arg[] }.

• name: the unique identifier of the command, passed to the Command.create function. If it’s a sidecar, this must be the value defined on tauri.conf.json > bundle > externalBin.
• cmd: the program that is executed on this configuration. If it’s a sidecar, this value is ignored.
• sidecar: whether the object configures a sidecar or a system program.
• args: the arguments that can be passed to the program. By default no arguments are allowed.
  • true means that any argument list is allowed.
  • false means that no arguments are allowed.
  • otherwise an array can be configured. Each item is either a string representing the fixed argument value or a { validator: string } that defines a regex validating the argument value.

Example scope configuration

CLI: git commit -m "the commit message"

Capability:

{
  "permissions": [
    {
      "identifier": "shell:allow-execute",
      "allow": [
        {
          "name": "run-git-commit",
          "cmd": "git",
          "args": ["commit", "-m", { "validator": "\\S+" }]
        }
      ]
    }
  ]
}

Usage:

import { Command } from '@tauri-apps/plugin-shell'
Command.create('run-git-commit', ['commit', '-m', 'the commit message'])

Trying to execute any API with a program not configured on the scope results in a promise rejection due to denied access.
