[wzmdbt7v2k-cmyk]

1. Use

npm create tauri-app@latest

to create the default project, keeping all options at their defaults.
2. Follow the Quick Start (30 seconds) tutorial to complete the integration.
3. Modify the frontend homepage code to call:

invoke('plugin:crabcamera|initialize_camera_system', {
  params: {
    camera_index: 0,
    resolution: "1920x1080",
    fps: 30,
    format: "MJPEG"
  }
})

4. Print the error message in the console.

Tauri Plugin Permissions Setup Notes

Background

I found that I was able to resolve this issue using some approaches, but since I’m not very familiar with Rust and can’t fully guarantee the correctness of the code, I didn’t submit a merge request.

Currently, Tauri requires Permissions in order to access plugin commands.

---

Command Registration

The following code defines the command list used by the plugin:

const COMMANDS: &[&str] = &[
    "initialize_camera_system",
    "get_available_cameras",
    "get_platform_info",
    "test_camera_system",
    "get_current_platform",
    "check_camera_availability",
    "get_camera_formats",
    "get_recommended_format",
    "get_optimal_settings",
    "get_system_diagnostics",
    "request_camera_permission",
    "check_camera_permission_status",
    "get_permission_status_string",
    "capture_single_photo",
    "capture_photo_sequence",
    "capture_with_quality_retry",
    "start_camera_preview",
    "stop_camera_preview",
    "release_camera",
    "get_capture_stats",
    "save_frame_to_disk",
    "save_frame_compressed",
    "set_frame_callback",
    "set_camera_controls",
    "get_camera_controls",
    "capture_burst_sequence",
    "set_manual_focus",
    "set_manual_exposure",
    "set_white_balance",
    "capture_hdr_sequence",
    "capture_focus_stack_legacy",
    "get_camera_performance",
    "test_camera_capabilities",
    "validate_frame_quality",
    "validate_provided_frame",
    "analyze_frame_blur",
    "analyze_frame_exposure",
    "update_quality_config",
    "get_quality_config",
    "capture_best_quality_frame",
    "auto_capture_with_quality",
    "analyze_quality_trends",
    "get_config",
    "update_config",
    "reset_config",
    "get_camera_config",
    "get_full_quality_config",
    "get_storage_config",
    "get_advanced_config",
    "update_camera_config",
    "update_full_quality_config",
    "update_storage_config",
    "update_advanced_config",
    "start_device_monitoring",
    "stop_device_monitoring",
    "poll_device_event",
    "get_monitored_devices",
    "capture_focus_stack",
    "capture_focus_brackets_command",
    "get_default_focus_config",
    "validate_focus_config",
];

---

Automatic Permission Generation

After applying the above modification, the plugin will automatically generate a permissions directory.
Inside the autogenerated and schemas subdirectories, TOML files for all commands will be generated automatically.

Example:

# Automatically generated - DO NOT EDIT!

"$schema" = "../../schemas/schema.json"

[[permission]]
identifier = "allow-analyze-frame-blur"
description = "Enables the analyze_frame_blur command without any pre-configured scope."
commands.allow = ["analyze_frame_blur"]

[[permission]]
identifier = "deny-analyze-frame-blur"
description = "Denies the analyze_frame_blur command without any pre-configured scope."
commands.deny = ["analyze_frame_blur"]

---

Enabling Permissions in the Application

The plugin permissions must then be declared in the application configuration, for example:

src-tauri/capabilities/default.json

{
  "$schema": "../gen/schemas/desktop-schema.json",
  "identifier": "default",
  "description": "Capability for the main window",
  "windows": [
    "main"
  ],
  "permissions": [
    "core:default",
    "opener:default",
    "crabcamera:allow-initialize-camera-system"
  ]
}

With this configuration, the plugin commands can be used normally in the project.

---

Required Cargo.toml Configuration

For the permission generation to take effect, the plugin crate must follow Tauri’s plugin naming conventions.

The Cargo.toml must be configured as follows:

[package]
name = "tauri-plugin-crabcamera"
links = "tauri_plugin_crabcamera"

Without this configuration, automatic permission generation will not work.

---

Application Initialization

The application can then be initialized in the usual way:

#[cfg_attr(mobile, tauri::mobile_entry_point)]
pub fn run() {
    tauri::Builder::default()
        .plugin(tauri_plugin_opener::init())
        .plugin(crabcamera::init())
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

After this, the plugin functions correctly as expected.
