🧠 tauri-plugin-hwinfo

A cross-platform Tauri plugin to fetch detailed system hardware information from the user's device, including CPU, RAM, GPU, and OS metadata — all accessible through both Rust and JavaScript/TypeScript APIs.

⚠️ Platform Support: Desktop-only. Mobile returns placeholder values.

⚠️ Testing: Only Windows is tested and confirmed working so far.

🔧 Features

• ✅ CPU Info (manufacturer, model, threads, max frequency)
• ✅ RAM Info (total memory in MB)
• ✅ GPU Info (model, manufacturer, VRAM in MB, CUDA support, Vulkan support)
• ✅ OS Info (OS name and version)
• ✅ Full Tauri v2 permissions support
• ✅ JS/TS bindings via @tauri-apps/api/core::invoke

📦 Installation

From Crates.io (Rust)

cargo add tauri-plugin-hwinfo

From GitHub (bleeding edge)

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

🛠️ Usage (Rust Backend)

Option 1: Auto-bind commands via invoke_handler (if calling from JS/TS manually)

#[cfg_attr(mobile, tauri::mobile_entry_point)]
pub fn run() {
    tauri::Builder::default()
        .plugin(tauri_plugin_hwinfo::init())
        .invoke_handler(tauri::generate_handler![
            tauri_plugin_hwinfo::get_cpu_info,
            tauri_plugin_hwinfo::get_gpu_info,
            tauri_plugin_hwinfo::get_ram_info,
            tauri_plugin_hwinfo::get_os_info
        ])
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

Option 2: Plugin-only setup (if using only the frontend API)

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

Use Option 1 if you want to manually expose commands to JS via invoke().

Use Option 2 if you're only using tauri-plugin-hwinfo's built-in TS API.

Add this to your src-tauri/capabilities/default.json:

{
  "permissions": [
    "hwinfo:allow-cpu-info",
    "hwinfo:allow-gpu-info",
    "hwinfo:allow-ram-info",
    "hwinfo:allow-os-info"
  ]
}

📌 Frontend API (JS/TS)

Install:

npm i tauri-plugin-hwinfo

Usage:

import {
  getCpuInfo,
  getRamInfo,
  getGpuInfo,
  getOsInfo,
} from "tauri-plugin-hwinfo";

async function logSystemInfo() {
  const cpu = await getCpuInfo();
  const ram = await getRamInfo();
  const gpu = await getGpuInfo();
  const os = await getOsInfo();

  console.log("CPU Info:", cpu);
  console.log("RAM Info:", ram);
  console.log("GPU Info:", gpu);
  console.log("OS Info:", os);
}
