From c635f6b9a2ba9c63ad5465be48bc6436202d43b7 Mon Sep 17 00:00:00 2001 From: UncleCode Date: Thu, 27 Mar 2025 21:35:13 +0800 Subject: [PATCH] refactor(browser): reorganize browser strategies and improve Docker implementation Reorganize browser strategy code into separate modules for better maintainability and separation of concerns. Improve Docker implementation with: - Add Alpine and Debian-based Dockerfiles for better container options - Enhance Docker registry to share configuration with BuiltinBrowserStrategy - Add CPU and memory limits to container configuration - Improve error handling and logging - Update documentation and examples BREAKING CHANGE: DockerConfig, DockerRegistry, and DockerUtils have been moved to new locations and their APIs have been updated. --- crawl4ai/browser/__init__.py | 14 +- .../browser/docker/alpine/connect.Dockerfile | 34 + .../browser/docker/alpine/launch.Dockerfile | 23 + crawl4ai/browser/docker/connect.Dockerfile | 32 +- .../browser/docker/debian/connect.Dockerfile | 23 + crawl4ai/browser/docker/launch.Dockerfile | 6 +- crawl4ai/browser/docker_config.py | 133 -- crawl4ai/browser/docker_registry.py | 140 +- crawl4ai/browser/docker_utils.py | 443 +++--- crawl4ai/browser/manager.py | 9 +- crawl4ai/browser/models.py | 143 ++ crawl4ai/browser/strategies.py | 1256 ----------------- crawl4ai/browser/strategies/__init__.py | 13 + crawl4ai/browser/strategies/base.py | 270 ++++ crawl4ai/browser/strategies/builtin.py | 394 ++++++ crawl4ai/browser/strategies/cdp.py | 359 +++++ .../{ => strategies}/docker_strategy.py | 205 ++- crawl4ai/browser/strategies/playwright.py | 284 ++++ docs/examples/crypto_analysis_example.py | 487 +++++-- tests/browser/docker/test_docker_browser.py | 20 +- 20 files changed, 2502 insertions(+), 1786 deletions(-) create mode 100644 crawl4ai/browser/docker/alpine/connect.Dockerfile create mode 100644 crawl4ai/browser/docker/alpine/launch.Dockerfile create mode 100644 crawl4ai/browser/docker/debian/connect.Dockerfile delete mode 100644 crawl4ai/browser/docker_config.py delete mode 100644 crawl4ai/browser/strategies.py create mode 100644 crawl4ai/browser/strategies/__init__.py create mode 100644 crawl4ai/browser/strategies/base.py create mode 100644 crawl4ai/browser/strategies/builtin.py create mode 100644 crawl4ai/browser/strategies/cdp.py rename crawl4ai/browser/{ => strategies}/docker_strategy.py (58%) create mode 100644 crawl4ai/browser/strategies/playwright.py diff --git a/crawl4ai/browser/__init__.py b/crawl4ai/browser/__init__.py index fb14b59d..af4d74c7 100644 --- a/crawl4ai/browser/__init__.py +++ b/crawl4ai/browser/__init__.py @@ -6,5 +6,17 @@ for browser creation and interaction. from .manager import BrowserManager from .profiles import BrowserProfileManager +from .models import DockerConfig +from .docker_registry import DockerRegistry +from .docker_utils import DockerUtils +from .strategies import ( + BaseBrowserStrategy, + PlaywrightBrowserStrategy, + CDPBrowserStrategy, + BuiltinBrowserStrategy, + DockerBrowserStrategy +) -__all__ = ['BrowserManager', 'BrowserProfileManager'] \ No newline at end of file +__all__ = ['BrowserManager', 'BrowserProfileManager', 'DockerConfig', 'DockerRegistry', 'DockerUtils', 'BaseBrowserStrategy', + 'PlaywrightBrowserStrategy', 'CDPBrowserStrategy', 'BuiltinBrowserStrategy', + 'DockerBrowserStrategy'] \ No newline at end of file diff --git a/crawl4ai/browser/docker/alpine/connect.Dockerfile b/crawl4ai/browser/docker/alpine/connect.Dockerfile new file mode 100644 index 00000000..96f77cef --- /dev/null +++ b/crawl4ai/browser/docker/alpine/connect.Dockerfile @@ -0,0 +1,34 @@ +# ---------- Dockerfile ---------- + FROM alpine:latest + + #
