Advanced Features Deep Dive
Auto-Waiting Mechanisms
One of the biggest differences in the Playwright vs Puppeteer comparison is how they handle waiting for elements:
// Puppeteer - Manual waiting
await page.waitForSelector('.content');
await page.click('.button');
// Playwright - Automatic waiting
await page.click('.button'); // Waits automatically
Network Interception
// Puppeteer
await page.setRequestInterception(true);
page.on('request', request => {
if (request.resourceType() === 'image')
request.abort();
else
request.continue();
});
// Playwright
await page.route('**/*.{png,jpg,jpeg}', route => route.abort());
Shadow DOM Handling
When comparing Puppeteer vs Playwright for modern web apps, Shadow DOM support becomes crucial:
// Puppeteer
await page.evaluateHandle(selector => {
return document.querySelector(selector).shadowRoot;
}, 'custom-element');
// Playwright
await page.locator('custom-element >> shadow=open').click();
Performance Optimization Guide
Memory Management in Long-Running Scripts
Both Playwright and Puppeteer need careful memory handling for production use:
// Common pattern for both tools
async function optimizedAutomation() {
const browser = await launch();
try {
const context = await browser.createIncognitoBrowserContext();
const page = await context.newPage();
// Your automation code here
await page.close();
await context.close();
} finally {
await browser.close();
}
}
Concurrent Execution Patterns
Feature | Playwright | Puppeteer |
---|---|---|
Browser contexts | Built-in isolation | Manual setup needed |
Worker threads | Native support | Requires extra setup |
Resource sharing | Automatic | Manual configuration |
Memory pooling | Built-in | Custom implementation |
Real-World Performance Tips
- Browser Instance Management
// Playwright's browser context
const browser = await playwright.chromium.launch();
const context1 = await browser.newContext();
const context2 = await browser.newContext();
// Puppeteer's approach
const browser = await puppeteer.launch();
const page1 = await browser.newPage();
const page2 = await browser.newPage();
- Resource Optimization
// Both tools - Optimal resource handling
await page.setRequestInterception(true);
page.on('request', request => {
if (request.resourceType() === 'image' || request.resourceType() === 'stylesheet')
request.abort();
else
request.continue();
});
Troubleshooting and Debugging
Common Error Patterns
When choosing between Playwright vs Puppeteer, debugging capabilities can be a deciding factor:
Error Type | Playwright Solution | Puppeteer Solution |
---|---|---|
Timeout | Built-in retry | Manual retry logic |
Element not found | Auto-waiting | Custom wait function |
Network issues | Automatic handling | Manual intervention |
Browser crashes | Auto-recovery | Manual recovery |
Advanced Debugging Features
// Playwright's trace viewer
await context.tracing.start({ screenshots: true, snapshots: true });
// ... your test code ...
await context.tracing.stop({ path: 'trace.zip' });
// Puppeteer's debugging
await page.evaluate(() => {
debugger;
});
