Tauri 2.0.0-alpha.4 Released

Tauri 1.2 Launch Hero Image

A new alpha release for the 2.0 has been published. This release includes all changes from the upcoming Tauri 1.3 release, an important breaking change on the HTTP client and native mobile capabilities for Tauri plugins.

Updating dependencies

Make sure to update both NPM and Cargo dependencies to the latest alpha release. You can update the NPM dependencies with:

npm install @tauri-apps/cli@next @tauri-apps/api@next

Recreate the mobile projects to use the new features:

Terminal window
rm -r src-tauri/gen
tauri android init
tauri ios init

HTTP Client Breaking Change

The default HTTP client using attohttpc has been removed due to issues with the development server proxy on Windows. All reqwest-* feature flags have been removed because reqwest is now the client we use.

Native Mobile Functionality for Tauri Plugins

A Tauri plugin now can access iOS via Swift and Android APIs via Kotlin or Java code, simplifying usage of platform interfaces such as camera or geolocation. To bootstrap the iOS and Android projects on an existing plugin, run tauri plugin ios add and tauri plugin android add. New plugins automatically include all the configuration needed to write native mobile code.

Here’s an example of a plugin that takes a string value and resolves an object:

Android plugin:

package com.plugin.example
import app.tauri.annotation.Command
import app.tauri.annotation.TauriPlugin
import app.tauri.plugin.JSObject
import app.tauri.plugin.Plugin
import app.tauri.plugin.Invoke
class ExamplePlugin(private val activity: Activity): Plugin(activity) {
fun ping(invoke: Invoke) {
val value = invoke.getString("value") ?: ""
val ret = JSObject()
ret.put("value", value)

iOS plugin:

import UIKit
import WebKit
import Tauri
class ExamplePlugin: Plugin {
@objc public func ping(_ invoke: Invoke) throws {
let value = invoke.getString("value")
invoke.resolve(["value": value as Any])
func initPlugin(name: SRString, webview: WKWebView?) {
Tauri.registerPlugin(webview: webview, name: name.toString(), plugin: ExamplePlugin())

Rust code to initialize the plugin:

use tauri::{
plugin::{Builder, TauriPlugin},
Manager, Runtime,
#[cfg(target_os = "ios")]
pub fn init<R: Runtime>() -> TauriPlugin<R> {
.setup(|app, api| {
#[cfg(target_os = "android")]
api.register_android_plugin("com.plugin.example", "ExamplePlugin")?;
#[cfg(target_os = "ios")]

Frontend code to call the plugin command:

import { invoke } from '@tauri-apps/api/tauri';
invoke('plugin:example|ping', { value: 'Tauri' }).then(({ value }) =>
console.log('Response', value)
