jwebs 1.0.0

A powerful and advanced web scraping and automation library for Python

jwebs

jwebs is a complete, high‑performance library for web scraping, crawling automation, and content analysis. It supports both HTTP/1.1 and HTTP/2 (user selectable) and includes built‑in caching, rate limiting, robots.txt handling, dynamic proxy rotation, distributed crawling (via Redis), data extraction, content differencing, uptime monitoring, Sitemap/RSS generation, and optional AI‑powered extraction.

---

Quick Start – Simple GET Request

from jwebs import JWebs

j = JWebs()
resp = j.GET("https://example.com")
print(f"Status: {resp.status}")
print(f"Content length: {len(resp.text)}")

---

Main Capabilities

· HTTP – HTTP/1.1 and HTTP/2 (user selectable), Keep‑Alive, automatic redirects, batch concurrent requests.

· Request Management – Two‑layer cache (memory + SQLite), rate limiting (Token Bucket), robots.txt respect, session management.

· Security & Flexibility – User‑Agent rotation, dynamic proxy rotation, client certificates (mTLS), SSL and security headers checking.

· Crawling & Automation – Simple crawler and distributed crawler (Redis) that can run across multiple machines.

· Data Extraction – Extract text, links, emails, phone numbers, prices, JSON‑LD, meta tags, images, social media links. · Content Analysis – Sentiment analysis, automatic translation, content differencing (diff).

· Monitoring – Uptime monitoring, performance testing (TTFB, page size), SEO and security audits.

· Utilities – Sitemap.xml generator, RSS feed generator, GraphQL client, async client.

· AI (optional) – Intelligent data extraction via natural language instructions (DeepSeek/OpenAI) and text summarization.

More Examples

HTTP/2 and Caching

from jwebs import JWebs

j = JWebs(http_version='2', use_cache=True)
title = j.GET_TITLE("https://http2.golang.org/")
print(f"Title: {title}")

Extracting Emails and Links

from jwebs import JWebs

j = JWebs()
emails = j.EXTRACT_EMAILS("https://example.com")
links = j.GET_LINKS("https://example.com", internal=True)
print(f"Emails: {emails}\nInternal Links: {len(links)}")

Distributed Crawling with Redis

from jwebs import JWebs

j = JWebs()
crawler = j.create_distributed_crawler(redis_url="redis://localhost:6379/0")
crawler.add_seed("https://example.com", depth=0)
crawler.crawl_worker(max_pages=10, max_depth=2, strict_page_limit=True)

results = crawler.get_all_results()
for url, info in results.items():
    print(f"{url} → {info.get('title', 'no title')}")

Security Audit

from jwebs import JWebs

j = JWebs()
report = j.SECURITY_AUDIT("https://example.com")
print(f"SSL valid: {report.ssl_valid}")
print(f"Security grade: {report.grade}")

Content Differencing

from jwebs import JWebs

j = JWebs()
snap1 = j.TAKE_SNAPSHOT("version1", "Hello world")
snap2 = j.TAKE_SNAPSHOT("version2", "Hello jwebs")
diff = j.COMPARE_SNAPSHOTS(snap1, snap2)
print(f"Similarity: {j.SIMILARITY('Hello world', 'Hello jwebs')}")

Uptime Monitor

from jwebs import JWebs
import time

j = JWebs()
j.MONITOR_URL("https://example.com", expected_status=200)
j.START_MONITORING()
time.sleep(5)
j.STOP_MONITORING()
