Jinsi ya Kutumia Lighthouse kwa Performance Audit

Google Lighthouse ni tool ya bure inayotathmini performance, accessibility, SEO, na best practices za website yako. Kutumia Lighthouse kunakusaidia kuboresha speed, usability, na search engine optimization ya website yako.

Jinsi ya Kutumia Lighthouse:

1. Kutumia Chrome DevTools:

Fungua website kwenye Google Chrome.

Bonyeza F12 au Ctrl+Shift+I kufungua DevTools.

Chagua tab ya Lighthouse.

Chagua category za audit (Performance, Accessibility, SEO, Best Practices).

Bonyeza Generate Report.

2. Kutumia CLI (Command Line Interface):
# Install Lighthouse globally
npm install -g lighthouse

# Run audit on website
lighthouse https://example.com --output html --output-path ./report.html

3. Kutumia Node.js API:
const lighthouse = require('lighthouse');
const chromeLauncher = require('chrome-launcher');

(async () => {
const chrome = await chromeLauncher.launch({chromeFlags: ['--headless']});
const options = {port: chrome.port, output: 'html'};
const runnerResult = await lighthouse('https://example.com', options);
require('fs').writeFileSync('report.html', runnerResult.report);
await chrome.kill();
})();


Ufafanuzi:

Lighthouse ina metrics kama First Contentful Paint (FCP), Largest Contentful Paint (LCP), na Cumulative Layout Shift (CLS).

Report itakuonyesha recommendations za kuboresha speed na usability.

Unaweza kutumia reports kwa presentations au internal audits.
