Tauri Plugin for Aptabase

This plugin allows you to instrument your app with events that can be analyzed in Aptabase, an Open Source, Privacy-First, and Simple Analytics for Mobile, Desktop, and Web Apps.

Install

Install the Core plugin by adding the following to your Cargo.toml file:

src-tauri/Cargo.toml

[dependencies]
tauri-plugin-aptabase = "1.3.0"

[dependencies]
tauri-plugin-aptabase = { git = "https://github.com/aptabase/tauri-plugin-aptabase" }

You can install the JavaScript Guest bindings using your preferred JavaScript package manager

npm add @aptabase/tauri

npm add https://github.com/aptabase/tauri-plugin-aptabase

Usage

First, you need to get your App Key from Aptabase, you can find it in the Instructions menu on the left side menu.

Then register the plugin with Tauri:

src-tauri/src/main.rs

#[tokio::main]
async fn main() {
    tauri::Builder::default()
        .plugin(tauri_plugin_aptabase::Builder::new("<YOUR_APP_KEY>").build()) // 👈 this is where you enter your App Key
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

And finally add aptabase:allow-track-event to your list Access Control List.

You can then start sending events from Rust by importing the tauri_plugin_aptabase::EventTracker trait and calling the track_event method on App, AppHandle or Window.

As an example, you can add app_started and app_exited events like this:

use tauri_plugin_aptabase::EventTracker;

#[tokio::main]
async fn main() {
    tauri::Builder::default()
        .plugin(tauri_plugin_aptabase::init("<YOUR_APP_KEY>".into()))
        .setup(|app| {
            app.track_event("app_started", None);
            Ok(())
        })
        .build(tauri::generate_context!())
        .expect("error while running tauri application")
        .run(|handler, event| match event {
            tauri::RunEvent::Exit { .. } => {
                handler.track_event("app_exited", None);
                handler.flush_events_blocking();
            }
            _ => {}
        })
}

The trackEvent function is also available through the JavaScript guest bindings:

import { trackEvent } from "@aptabase/tauri";

trackEvent("save_settings") // An event with no properties
trackEvent("screen_view", { name: "Settings" }) // An event with a custom property

A few important notes:

1. The plugin will automatically enhance the event with some useful information, like the OS, the app version, and other things.
2. You're in control of what gets sent to Aptabase. This plugin does not automatically track any events, you need to call trackEvent manually.
   • Because of this, it's generally recommended to at least track an event at startup
3. You do not need to await for the trackEvent function, it'll run in the background.
4. Only strings and numbers values are allowed on custom properties

Error Reporting

Error reporting is in beta. Reports appear on the Errors page of your Aptabase dashboard.

Use track_error to report errors you've caught and handled in Rust, through the tauri_plugin_aptabase::ErrorTracker trait on App, AppHandle or Window:

use tauri_plugin_aptabase::ErrorTracker;

if let Err(err) = std::fs::read_to_string("settings.json") {
    app.track_error(&err); // severity: error
}

The trackError function does the same from JavaScript. Add aptabase:allow-track-error to your Access Control List first:

import { trackError } from "@aptabase/tauri";

try {
  await saveSettings();
} catch (error) {
  trackError(error); // severity: error
}

For errors your app can't recover from, mark the report as fatal:

trackError(error, { fatal: true }); // severity: fatal

use tauri_plugin_aptabase::{ErrorReport, ErrorTracker};

app.track_error_report(ErrorReport::from_error(&err).with_fatal(true)); // severity: fatal

To also report crashes and uncaught errors automatically, enable crash reporting when you register the plugin:

tauri::Builder::default()
    .plugin(tauri_plugin_aptabase::Builder::new("<YOUR_APP_KEY>").with_crash_reporting().build())

A few important notes about error reporting:

1. A panic on the main thread ends your app: it's reported as a fatal crash, and the app waits up to three seconds for the report to be sent before it exits. A panic in an async command or a task on Tauri's async runtime ends only that task (taskException), and one on a thread of your own ends only that thread (unhandled): both are reported with severity error. A hook set with with_panic_hook still runs.
2. With crash reporting on, the webview's uncaught errors (unhandled) and unhandled promise rejections (taskException) are reported too. This needs the aptabase:allow-track-error permission.
3. Each report includes the error type, message, stack trace, severity (error or fatal) and how it was captured (handled, unhandled, taskException or crash). A Rust error is reported with its type name and the errors that caused it; a panic with its location and a backtrace.
4. Errors count against a separate monthly error quota. When it is exhausted, the server rejects new reports until it resets, and the plugin drops them instead of retrying.
5. Crashes that don't go through Rust's panic handler (a segfault or an abort in native code) aren't captured.

Providing the APTABASE_KEY via .env

It's possible to load the APTABASE_KEY from a .env file at compile time using the dotenvy_macro crate. The .env file needs to be in the src-tauri directory for the dotevny_macro crate to find it properly.

Add the use declaration to where you are building the tauri app (likely lib.rs for Tauri v2), and then call it where you would put the key.

use tauri_plugin_aptabase::EventTracker;
use dotenvy_macro::dotenv;

#[cfg_attr(mobile, tauri::mobile_entry_point)]
/// This function sets up and runs a Rust application using the Tauri framework, with various plugins
/// and event handlers.
pub fn run() {
    tauri::Builder::default()
        .build(tauri::generate_context!())
        .plugin(tauri_plugin_aptabase::Builder::new(dotenv!("APTABASE_KEY")).build())
        .expect("Error when building tauri app")
        .run(|handler, event| match event {
            tauri::RunEvent::Exit { .. } => {
                handler.track_event("app_exited", None);
                handler.flush_events_blocking();
            }
            tauri::RunEvent::Ready { .. } => {
                handler.track_event("app_started", None);
            }
            _ => {}
        });
}

Delivery

Events are queued in memory and sent in the background: every 60 seconds in release builds and every 2 seconds in debug builds (set flush_interval in InitOptions to change it), and whenever you call flush_events_blocking().

• Each request carries up to 25 events.
• If a request doesn't reach the server (no network, a timeout) or the server answers with a 5xx status, its events stay queued for the next flush.
• If the server answers with any other unsuccessful status, such as a 4xx, its events are dropped.
• The queue isn't saved to disk.

Requests use the system proxy settings on macOS and Windows, and the HTTP_PROXY, HTTPS_PROXY, ALL_PROXY and NO_PROXY environment variables on every platform.

TLS backends

The plugin sends events with reqwest. You choose its TLS backend with one of these Cargo features:

Feature	Backend
default-tls (default)	reqwest's default backend, currently rustls
rustls-tls	rustls
native-tls	The platform's TLS library: OpenSSL on Linux and Android, Security.framework on Apple platforms, SChannel on Windows

To switch backend, turn off the default features:

[dependencies]
tauri-plugin-aptabase = { version = "1.3", default-features = false, features = ["native-tls"] }

Neither default-tls nor rustls-tls needs OpenSSL, so you can cross-compile for Android and Linux without it.
