How to get the system information in Electron?

Retrieving system information in Electron can be achieved through multiple approaches, primarily involving Node.js's os module and Electron's own process module. Below, I will detail two primary methods and provide code examples to demonstrate implementation.

1. Using Node.js's os Module

Node.js's built-in os module provides various methods to retrieve system-level information, such as CPU details, memory usage, and the operating system. Since Electron is built on top of Node.js, we can directly utilize this module within Electron's main process.

Example code:

javascript
const os = require('os');

function getSystemInfo() {
    console.log('Operating System:', os.platform());
    console.log('System Type:', os.type());
    console.log('System Version:', os.release());
    console.log('Total Memory:', os.totalmem(), 'bytes');
    console.log('Free Memory:', os.freemem(), 'bytes');
    console.log('CPU Core Count:', os.cpus().length);
}

getSystemInfo();

In this example, we leverage multiple functions from the os module to output details such as the operating system type, version, memory usage, and CPU core count.

2. Using Electron's process Module

Electron's process module extends Node.js's process module, adding desktop application-specific features like retrieving the user's application data path.

Example code:

javascript
const electron = require('electron');

function getElectronSpecificInfo() {
    console.log('Electron Version:', process.versions.electron);
    console.log('Chrome Version:', process.versions.chrome);
    console.log('User Data Path:', electron.app.getPath('userData'));
}

getElectronSpecificInfo();

In this example, we retrieve the current Electron version and its embedded Chrome version via process.versions. Additionally, we use electron.app.getPath to obtain the user data path, which is commonly used for storing application configuration files and data.

Conclusion

By employing these two methods, we can effectively retrieve system information within Electron applications. Selecting the appropriate method based on requirements to obtain specific system information helps us better understand the user's runtime environment, thereby optimizing application performance and user experience.
