About This Book

This book teaches you to build a complete, production-ready web scraping system using a declarative JSON configuration approach. Rather than writing custom Python for every target, you express each scraping task as a JSON object that your engine interprets - an approach that scales, composes, and that AI agents can generate autonomously.

The book is structured in five parts:

Part Theme What you build
1 · Foundations Why scraping, rendering, JSON contract Mental model
2 · Extraction Selectors, field types, pagination Config vocabulary
3 · Rendering Static, Playwright, auto-fallback Full engine
4 · Scale Scheduling, storage, change detection Production ops
5 · AI Agents Config generation, autonomous loop, MCP AI-first scraping

The Core Idea

A scraper config is a JSON object that completely specifies a scraping task:

{
  "render_mode": "static",
  "sources": [{
    "url_template": "https://jobs.example.com/listings?page={n}",
    "pagination": {"start": 1, "step": 1, "max_pages": 50}
  }],
  "listing": {
    "link_selector": "a.job-link",
    "link_prefix": "https://jobs.example.com"
  },
  "fields": {
    "title":    {"selector": "h1.job-title",  "retrieve": "plaintext"},
    "company":  {"selector": ".company-name", "retrieve": "plaintext"},
    "salary":   {"selector": ".salary",       "retrieve": "regexp",
                 "pattern": "\\$([\\d,]+)"},
    "tags":     {"selector": ".skill-tag",    "retrieve": "plaintext",
                 "multiple": true}
  }
}

This config drives pagination, link following, field extraction, and regex transforms - without a single line of custom Python.
