tauri-plugin-profiling

A Tauri v2 plugin for CPU profiling with flamegraph generation.

Provides actual CPU profiling using sampling-based techniques, complementing tauri-plugin-tracing which provides span timing (wall-clock time including I/O waits).

Installation

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

pnpm add @tauri-apps/plugin-profiling

Usage

Rust

use tauri_plugin_profiling::ProfilingExt;

tauri::Builder::default()
    .plugin(tauri_plugin_profiling::init())
    .setup(|app| {
        app.start_cpu_profile()?;
        // ... work ...
        let result = app.stop_cpu_profile()?;
        println!("Flamegraph: {:?}", result.flamegraph_path);
        Ok(())
    })

JavaScript

import { startCpuProfile, stopCpuProfile, withProfiling } from '@tauri-apps/plugin-profiling';

await startCpuProfile({ frequency: 100 });
await doExpensiveOperation();
const result = await stopCpuProfile();

// Or use the convenience wrapper
const { result, profile } = await withProfiling(async () => processData());
