Tauri Plugin system-info

TypeScript Documentation: https://huakunshen.github.io/tauri-plugin-system-info Rust Documentation: https://docs.rs/crate/tauri-plugin-system-info

This is a Tauri plugin for reading system information.

• Rust Crate: https://crates.io/crates/tauri-plugin-system-info
• TypeScript API: https://www.npmjs.com/package/tauri-plugin-system-info-api

Installation

If you are installing from npm and crates.io package registry, make sure the versions for both packages are the same, otherwise, the API may not match.

For Tauri v1 app, use version 1.x, for Tauri v2 app, use version 2.x. (this applies to both npm and crates.io packages)

Rust Install

cargo add tauri-plugin-system-info within src-tauri to add the package.

Or add the following to your Cargo.toml for the latest unpublished version (not recommanded).

1tauri-plugin-system-info = { git = "https://github.com/HuakunShen/tauri-plugin-system-info", branch = "v1" } # use v2 branch for Tauri v2 plugin

NPM Install

Run the following to install JavaScript/TypeScript API package.

1npm i tauri-plugin-system-info-api
2# npm add https://github.com/HuakunShen/tauri-plugin-system-info # or this for latest unpublished version (not recommended)

In main.rs, add the following to your tauri::Builder:

1fn main() {
2    tauri::Builder::default()
3        .plugin(tauri_plugin_system_info::init())
4        .run(tauri::generate_context!())
5        .expect("error while running tauri application");
6}

Info Supported

• CPU
• Network
• Process
• Memory
• Hostname
• Kernel Version
• OS Version
• Battery

Third Party Libraries Used

• sysinfo

API

TypeScript

All TypeScript APIs can be found in api.ts.

Return type of each API is added. The object structures can be found in type.ts.

Valibot was used to define type schema and infer TypeScript types. You can import the types exported from the npm package.

The exported Valibot schemas can be used to parse data and make sure the data returned from rust APIs match the desired structure defined in schema.

1import {
2  allSysInfo,
3  memoryInfo,
4  staticInfo,
5  cpuInfo,
6  AllSystemInfo,
7  StaticInfo,
8  MemoryInfo,
9  CpuInfo,
10  batteries,
11  Batteries,
12} from "tauri-plugin-system-info-api";
13
14console.log(AllSystemInfo.parse(await allSysInfo()));
15console.log(MemoryInfo.parse(await memoryInfo()));
16console.log(StaticInfo.parse(await staticInfo()));
17console.log(CpuInfo.parse(await cpuInfo()));
18console.log(Batteries.parse(await batteries()));

Rust

The API functions in Rust are all exported, so that you can also build your own commands.

Here is a simple example:

1use tauri_plugin_system_info::utils::{SysInfo, SysInfoState};
2use tauri_plugin_system_info::commands;
3use tauri_plugin_system_info::model::Cpu;
4
5#[tauri::command]
6fn cpu_count() -> Result<usize, String> {
7    let state = SysInfoState::default();
8    let sysinfo = state.sysinfo.lock().unwrap();
9    let cpu_count = sysinfo.cpu_count();
10    Ok(cpu_count)
11}

See https://docs.rs/crate/tauri-plugin-system-info/ for full rust documentation.

SysInfo is the API struct that can be used to access all information. It's like a wrapper for sysinfo APIs and other crates. The reason for doing this is, some structs in third party libraries cannot be cloned or serialized, and thus cannot be sent to the frontend.

I aggregate all the APIs, do structure conversion and serilization with custom code.
