Бібліотека для побудови графу структури веб-сайтів.

Встановлення

pip install graph-crawler

Додаткові залежності:

pip install graph-crawler[playwright]    # JavaScript сайти
pip install graph-crawler[embeddings]    # Векторизація
pip install graph-crawler[mongodb]       # MongoDB storage
pip install graph-crawler[all]           # Все

Використання

import graph_crawler as gc

# Базове сканування
graph = gc.crawl("https://example.com", max_depth=2, max_pages=50)

print(f"Сторінок: {len(graph.nodes)}")
print(f"Посилань: {len(graph.edges)}")

# Збереження
gc.save_graph(graph, "site.json")

Async API

import asyncio
import graph_crawler as gc

async def main():
    graph = await gc.async_crawl("https://example.com")
    return graph

graph = asyncio.run(main())

Параметри crawl()

Параметр Default Опис
max_depth 3 Глибина сканування
max_pages 100 Ліміт сторінок
same_domain True Тільки поточний домен
request_delay 0.5 Затримка між запитами (сек)
timeout 300 Загальний таймаут (сек)
driver "http" Драйвер: http, playwright

URL Rules

from graph_crawler import crawl, URLRule

rules = [
    URLRule(pattern=r"\.pdf$", should_scan=False),
    URLRule(pattern=r"/admin/", should_scan=False),
    URLRule(pattern=r"/products/", priority=10),
]

graph = crawl("https://example.com", url_rules=rules)

Операції з графом

# Статистика
stats = graph.get_stats()

# Пошук
node = graph.get_node_by_url("https://example.com/page")

# Об'єднання графів
merged = graph1 + graph2

# Експорт
graph.export_edges("edges.csv", format="csv")
graph.export_edges("graph.dot", format="dot")

Драйвери

Драйвер Призначення
http Статичні сайти (default)
playwright JavaScript/SPA сайти
# Playwright для JS сайтів
graph = gc.crawl("https://spa-site.com", driver="playwright")
