Mbbrowser Anti-Association Browser

# Upgrading instructions for Playwright engine

# Playwright Automation Engine Support

New Feature | Major Update | Recommended

# 📋 Feature Overview

This update adds Playwright engine support to MBBrowser's automation script functionality, forming three major automation solutions together with existing Puppeteer and Selenium engines, providing users with more powerful and modern browser automation capabilities.

✅ Update Highlights: Supports JavaScript, Python, and Java languages, automatic environment configuration, zero-configuration usage!

# ✨ Core Features

# 1. Comprehensive Language Support

Language Engine Type Runtime Environment Features
JavaScript Playwright Node.js Native support, optimal performance
Python Playwright Virtual Environment Automatic virtual environment activation, environment isolation
Java Playwright JDK + Node.js Automatic driver extraction, automated configuration

# 2. Intelligent Environment Management

# Python Virtual Environment

# Auto-generated startup script
call Playwright\Scripts\activate
Playwright\Scripts\python.exe "script_path"

✅ Automatic virtual environment activation
✅ Environment isolation, avoiding conflicts

# Java Driver Auto-extraction

# Auto-extraction on first run
if not exist package\cli.js (
  jar xf lib\driver-bundle.jar
  move driver\win32_x64\package package
)

✅ Smart detection
✅ Automatic extraction and configuration

# Independent Bat File Management

Python non-debug mode:
Each script generates an independent bat file (named with SESSION_UNIQUE_ID)

✅ Avoid concurrent conflicts
✅ Automatic cleanup mechanism

# 3. Unified CDP Connection Method

All languages connect to the launched Chrome instance via Chrome DevTools Protocol (CDP):

// JavaScript
const browser = await chromium.connectOverCDP(ws_endpoint);

# Python
browser = p.chromium.connect_over_cdp(ws_endpoint)

// Java
Browser browser = playwright.chromium().connectOverCDP(ws_endpoint);

# 🆚 Three Engine Comparison

Feature Puppeteer Selenium Playwright (New)
Language Support JS only JS/Python/Java JS/Python/Java
Connection Method WebSocket WebDriver CDP (Faster)
API Modernization ⭐⭐⭐ ⭐⭐ ⭐⭐⭐⭐⭐
Cross-browser Chrome only Multiple browsers Chrome/Firefox/Safari
Auto-wait Manual required Limited support Smart auto-wait
Network Interception Supported Not supported Strong support
Multi-tab Supported Supported Native excellent support
Community Activity High High Very High (Microsoft maintained)

# 🔧 Technical Implementation Highlights

# 1. Intelligent Script Identification System

std::string g_sScriptFlag[3][3] = {
    {"std_mbscript_pup_js", "", ""},              // Puppeteer
    {"", "std_mbscript_sele_py", "std_mbscript_sele_jv"},  // Selenium
    {"std_mbscript_play_js", "std_mbscript_play_py", "std_mbscript_play_jv"}  // Playwright
};

✅ Automatically identifies script types through identifiers, ensuring correct runtime environment

# 2. Independent Bat File Management

Python Script Non-debug Mode:

  • Each script generates an independent bat file (named with SESSION_UNIQUE_ID)
  • Avoids multi-script concurrent conflicts
  • Automatic cleanup mechanism

Java Script Playwright Type:

  • Automatically detects and extracts drivers
  • Sets Node.js path
  • Intelligent error handling and prompts

# 3. Automatic Port and Key Replacement

Automatically replaces connection information in scripts at runtime:

// JavaScript & Python Playwright
size_t posStart = sJs.find("ws://localhost");
sJs.replace(sJs.begin() + posStart, sJs.begin() + posEnd, 
           pItem->sChromeKey.c_str());

// Java Playwright
size_t posStart = sJs.find("String ws_endpoint = \"");
sJs.replace(sJs.begin() + posStart, sJs.begin() + posEnd, 
           pItem->sChromeKey.c_str());

# 📝 Standard Script Templates

# JavaScript Playwright Template

const { chromium } = require('playwright');
const ws_endpoint = 'ws://localhost:9223/...';  // Auto-replaced

const browser = await chromium.connectOverCDP(ws_endpoint);
// Get existing page or create new page
// Execute automation operations...

# Python Playwright Template

from playwright.sync_api import sync_playwright
ws_endpoint = "ws://localhost:9234/..."  # Auto-replaced

with sync_playwright() as p:
    browser = p.chromium.connect_over_cdp(ws_endpoint)
    # Automation operations...

# Java Playwright Template

import com.microsoft.playwright.*;

System.setProperty("playwright.skip.browser.download", "1");
Playwright playwright = Playwright.create(...);
Browser browser = playwright.chromium().connectOverCDP(ws_endpoint);
// Automation operations...

# 🚀 User Experience Enhancement

# Zero-Configuration Startup

  1. User only needs to select "Playwright" engine
  2. Select language (JS/Python/Java)
  3. Write script, run with one click
  4. All environment configuration completed automatically

# Environment Isolation

  • ✅ Python uses independent virtual environment (Playwright directory)
  • ✅ Java driver auto-extraction, no system pollution
  • ✅ JavaScript uses project-level node_modules

# Intelligent Error Handling

  • ✅ Missing driver? Auto-extract
  • ✅ Node.js not found? Auto-configure PATH
  • ✅ Detailed error logs and prompts

# 📊 Performance Comparison

Metric Selenium Puppeteer Playwright
Startup Speed 2-3 seconds 1-2 seconds 1-2 seconds
Operation Response Slower Fast Fastest
Stability ⭐⭐⭐ ⭐⭐⭐⭐ ⭐⭐⭐⭐⭐
Resource Usage Medium Low Low

# 📦 System Requirements

# From Selenium to Playwright

Selenium Python:

from selenium import webdriver
driver = webdriver.Chrome(...)
driver.get('https://example.com')

Playwright Python:

from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    browser = p.chromium.connect_over_cdp(ws_endpoint)
    page = browser.contexts[0].pages[0]
    page.goto('https://example.com')

# From Puppeteer to Playwright

Puppeteer:

const puppeteer = require('puppeteer-core');
const browser = await puppeteer.connect({...});

Playwright:

const { chromium } = require('playwright');
const browser = await chromium.connectOverCDP(ws_endpoint);

# 💡 Upgrade Recommendations

# ✅ Scenarios Suitable for Playwright

  • Need modern API and better asynchronous support
  • Need network layer control (intercept/modify requests)
  • Need multi-tab/multi-context management
  • Need cross-browser testing
  • Need more stable automation scripts

# ⚡ Scenarios to Continue Using Selenium

  • Existing large Selenium script base, high migration cost
  • Need mobile browser support (Appium)
  • Team more familiar with Selenium ecosystem

# ⚡ Scenarios to Continue Using Puppeteer

  • Only need Chrome/Chromium support
  • Simple scripts, no complex functionality needed
  • Pursuit of minimal dependencies

# ⚡ Quick Start

# Step 1: Select Engine

In the automation script management interface, select "Playwright" engine type

# Step 2: Select Language

Choose according to needs: JavaScript, Python, or Java

# Step 3: Write Script

System automatically generates standard templates for the selected language, including Chrome connection code

# Step 4: Run with One Click

Click run, system automatically:

  1. Detects and configures runtime environment
  2. Replaces connection endpoint and key
  3. Activates necessary virtual environment (Python)
  4. Extracts drivers (Java)
  5. Executes script and connects to Chrome instance

⚠️ Important Notes:

  • Using Java language requires installing corresponding language environment packages. You can download Java environment packages by creating a new script window, selecting Playwright script, and clicking Java language download
  • When using Playwright scripts with Python, if you need to install other components, please first execute "Playwright\Scripts\activate" and then call pip for installation
  • When running the script, it is recommended to first set the client to run in standalone mode
