description	Assists users with migrating Tauri applications from v1 to v2 stable, and from v2 beta to v2 stable, covering breaking changes, configuration updates, API migrations, and plugin system changes.

Tauri Migration Guide

This skill covers migrating Tauri applications to v2 stable from either v1 or v2 beta.

Migration Paths

Source Version	Target	Complexity
Tauri v1.x	v2 stable	High - significant breaking changes
Tauri v2 beta	v2 stable	Low - minor breaking changes

---

Automated Migration

Both migration paths support automated migration via the Tauri CLI:

# Install latest CLI first
npm install @tauri-apps/cli@latest

# Run migration
npm run tauri migrate
# or: yarn tauri migrate | pnpm tauri migrate | cargo tauri migrate

IMPORTANT: The migrate command automates most tasks but is NOT a complete substitute for manual review. Always verify changes after running.

V1 to V2 Migration

Configuration File Changes

BREAKING: Top-Level Structure Changes

Before (v1):

{
  "package": {
    "productName": "my-app",
    "version": "1.0.0"
  },
  "tauri": {
    "bundle": { ... },
    "allowlist": { ... }
  }
}

After (v2):

{
  "productName": "my-app",
  "version": "1.0.0",
  "mainBinaryName": "my-app",
  "identifier": "com.example.myapp",
  "app": { ... },
  "bundle": { ... }
}

Key Renames

v1 Path	v2 Path
package.productName	productName (top-level)
package.version	version (top-level)
tauri	app
tauri.bundle	bundle (top-level)
tauri.bundle.identifier	identifier (top-level)
tauri.systemTray	app.trayIcon
build.distDir	frontendDist
build.devPath	devUrl

BREAKING: New Required Field

Add mainBinaryName matching your productName - this is no longer automatic:

{
  "productName": "My App",
  "mainBinaryName": "My App"
}

Bundle Configuration Reorganization

Platform-specific bundle configs moved under their platform key:

Before:

{
  "tauri": {
    "bundle": {
      "dmg": { ... },
      "deb": { ... }
    }
  }
}

After:

{
  "bundle": {
    "macOS": {
      "dmg": { ... }
    },
    "linux": {
      "deb": { ... }
    }
  }
}

Updater Configuration

If using the app updater, add to bundle config:

{
  "bundle": {
    "createUpdaterArtifacts": "v1Compatible"
  }
}

Use "v1Compatible" for existing distributions to maintain backward compatibility.

---

BREAKING: Allowlist Replaced with Capabilities

The v1 allowlist system is completely replaced with a capability-based ACL system.

Creating Capabilities

Create JSON files in src-tauri/capabilities/:

src-tauri/capabilities/default.json:

{
  "identifier": "default",
  "description": "Default capabilities for the main window",
  "windows": ["main"],
  "permissions": [
    "core:default",
    "shell:allow-open",
    "dialog:allow-open",
    "fs:allow-read-text-file"
  ]
}

The tauri migrate command auto-generates capabilities from your v1 allowlist.

---

Cargo.toml Changes

Removed Features

These features no longer exist in v2:

• reqwest-client
• reqwest-native-tls-vendored
• process-command-api
• shell-open-api
• windows7-compat
• updater
• system-tray

New Features

• linux-protocol-body - Custom protocol request body parsing support

BREAKING: API Module Removal

The entire api module is removed. Functionality moved to plugins:

v1 API	v2 Replacement
tauri::api::dialog	tauri-plugin-dialog
tauri::api::http	tauri-plugin-http
tauri::api::process	tauri-plugin-process
tauri::api::path functions	tauri::Manager::path

BREAKING: Rust API Changes

Removed APIs

v1	v2 Alternative
App::clipboard_manager	tauri-plugin-clipboard-manager
App::global_shortcut_manager	tauri-plugin-global-shortcut
App::get_cli_matches	tauri-plugin-cli
tauri::updater	tauri-plugin-updater

Renamed Types/Methods

v1	v2
Window	WebviewWindow
Manager::get_window	Manager::get_webview_window

Menu API Changes

Before:

use tauri::{Menu, CustomMenuItem};
let menu = Menu::new()
    .add_item(CustomMenuItem::new("quit", "Quit"));

After:

use tauri::menu::{MenuBuilder, MenuItemBuilder};
let menu = MenuBuilder::new(app)
    .item(&MenuItemBuilder::with_id("quit", "Quit").build(app)?)
    .build()?;

Tray API Changes

Before:

use tauri::SystemTray;
SystemTray::new().with_menu(menu);

After:

use tauri::tray::TrayIconBuilder;
TrayIconBuilder::new()
    .menu(&menu)
    .on_menu_event(|app, event| { ... })
    .on_tray_icon_event(|tray, event| { ... })
    .build(app)?;

---

BREAKING: JavaScript API Changes

Package Renames

v1	v2
@tauri-apps/api/tauri	@tauri-apps/api/core
@tauri-apps/api/window	@tauri-apps/api/webviewWindow

Core API Reduction

The core @tauri-apps/api package now only includes:

• core
• path
• event
• webviewWindow

All other APIs require plugin packages.

---

BREAKING: Plugin Migration

All formerly built-in APIs are now separate plugins:

v1 Import	v2 Plugin Package
@tauri-apps/api/cli	@tauri-apps/plugin-cli
@tauri-apps/api/clipboard	@tauri-apps/plugin-clipboard-manager
@tauri-apps/api/dialog	@tauri-apps/plugin-dialog
@tauri-apps/api/fs	@tauri-apps/plugin-fs
@tauri-apps/api/global-shortcut	@tauri-apps/plugin-global-shortcut
@tauri-apps/api/http	@tauri-apps/plugin-http
@tauri-apps/api/notification	@tauri-apps/plugin-notification
@tauri-apps/api/os	@tauri-apps/plugin-os
@tauri-apps/api/process	@tauri-apps/plugin-process
@tauri-apps/api/shell	@tauri-apps/plugin-shell
@tauri-apps/api/updater	@tauri-apps/plugin-updater

Installing Plugins

# JavaScript
npm install @tauri-apps/plugin-fs

# Rust (add to Cargo.toml)
cargo add tauri-plugin-fs

Register plugins in your Rust code:

fn main() {
    tauri::Builder::default()
        .plugin(tauri_plugin_fs::init())
        .run(tauri::generate_context!())
        .expect("error running app");
}

BREAKING: File System Plugin Changes

Function renames in @tauri-apps/plugin-fs:

v1	v2
createDir	mkdir
readBinaryFile	readFile
writeBinaryFile	writeFile
removeDir	remove
removeFile	remove
renameFile	rename
Dir enum	BaseDirectory

BREAKING: Event System Changes

v1	v2
emit()	Broadcasts to ALL listeners (behavior change)
N/A	emit_to() - target specific event targets
listen_global	listen_any

BREAKING: Windows Origin URL

Production Windows apps now serve from http://tauri.localhost instead of https://.

Impact: IndexedDB and cookies will reset unless you preserve the old behavior:

{
  "app": {
    "windows": [{
      "useHttpsScheme": true
    }]
  }
}

BREAKING: Environment Variables

v1	v2
TAURI_PRIVATE_KEY	TAURI_SIGNING_PRIVATE_KEY
TAURI_KEY_PASSWORD	TAURI_SIGNING_PRIVATE_KEY_PASSWORD
TAURI_DEV_SERVER_PORT	TAURI_CLI_PORT
Platform variables	Now prefixed TAURI_ENV_

Mobile Support Setup

To target mobile alongside desktop:

1. Update Cargo.toml:

[lib]
name = "app_lib"
crate-type = ["staticlib", "cdylib", "rlib"]

2. Rename src/main.rs to src/lib.rs:

#[cfg_attr(mobile, tauri::mobile_entry_point)]
pub fn run() {
    tauri::Builder::default()
        .run(tauri::generate_context!())
        .expect("error running app");
}

3. Create new src/main.rs:

fn main() {
    app_lib::run();
}

---

V2 Beta to V2 Stable Migration

BREAKING: Core Permission Prefix

All core permissions now require the "core:" prefix:

Before (beta):

{
  "permissions": [
    "path:default",
    "event:default",
    "window:default"
  ]
}

After (stable):

{
  "permissions": [
    "core:path:default",
    "core:event:default",
    "core:window:default"
  ]
}

Simplified alternative: Use "core:default" to include all default core permissions:

{
  "permissions": ["core:default"]
}

---

BREAKING: Mobile Dev Server Configuration

The mobile development server no longer exposes across networks. Traffic tunnels directly from local machine to devices.

Before (beta):

const mobile = !!/android|ios/.exec(process.env.TAURI_ENV_PLATFORM);
export default {
  server: {
    host: mobile ? '0.0.0.0' : false
  }
};

After (stable):

const host = process.env.TAURI_DEV_HOST;
export default {
  server: {
    host: host || false
  }
};

Remove dependency on the internal-ip NPM package if previously used.

iOS Device Development: Requires additional steps. Use:

tauri ios dev --force-ip-prompt

Select the device's TUN address when prompted.

Common Issues

Issue	Solution
Permission denied errors	Check src-tauri/capabilities/ files for required permissions
IndexedDB/localStorage lost (Windows)	Set useHttpsScheme: true in window config
Plugin not found	Add to Cargo.toml, register with .plugin(), install npm package
Mobile build fails	Verify [lib] section in Cargo.toml and src/lib.rs with mobile entry point
