this.info_browser

Overview

The this.info_browser property provides detailed information about the user's browser, operating system, and device. This is powered by the my-ua-parser library and includes data such as the browser engine, OS, CPU architecture, and more. It is ideal for advanced browser detection and analytics.

Usage

To access detailed browser and system information, use this.info_browser in your class:

class MyApp extends JsBaseClass {
    async handle() {
        // Log detailed browser information
        this.console.log('User Agent:', this.info_browser.ua);
        this.console.log('Browser Name:', this.info_browser.browser.name);
        this.console.log('Browser Version:', this.info_browser.browser.version);
        this.console.log('Browser Engine:', this.info_browser.engine.name);
        this.console.log('Operating System:', this.info_browser.os.name);
        this.console.log('CPU Architecture:', this.info_browser.cpu.architecture);

        // Example: Apply OS-specific logic
        if (this.info_browser.os.name === 'Linux') {
            this.console.log('Running on a Linux system.');
        } else {
            this.console.log('Running on a different OS.');
        }
    }
}

// Initialize the app
const app = new MyApp();
app.init();
