Requires Python: >=3.12

# SwiftCrawl

A powerful, flexible web scraping abstraction layer that seamlessly handles both lightweight HTTP requests and full browser automation with anti-detection capabilities.

## Highlights

- **Dual-mode sessions** – `SwiftCrawl` seamlessly switches between BrowserForge-powered HTTP requests and Camoufox browser automation.
- **Async-first architecture** – every client, crawler component, and CLI workflow is `asyncio` friendly for massive concurrency.
- **Crawler engine** – Scrapy-inspired scheduler, downloader, and CLI (`swiftcrawl crawl`) with retries, priorities, and Playwright warmup support.
- **Items & Fields** – define strongly-typed `Item` objects with `.Field(serializer=...)` hooks for clean output serialization.
- **Project bootstrapper** – `swiftcrawl init <project>` scaffolds spiders, settings, and sample items in seconds.
- **Unified response parsing** – `Response.json()/soup()/tree()` keep parsing ergonomic across HTTP and browser modes.

## Installation

### Using pip/uv (Local Development)

```bash
# Initialize with UV (recommended)
uv init --name myproject
cd myproject

# Add SwiftCrawl
uv add swiftcrawl

# Install Camoufox browser (for browser mode)
camoufox fetch
```

### Using Docker (Production Ready)

SwiftCrawl provides pre-built Docker images for easy deployment:

```bash
# Pull the latest full image (with browser support)
docker pull maxilr/swiftcrawl-runner:latest

# Or pull the lite image (HTTP-only, smaller size)
docker pull maxilr/swiftcrawl-runner:lite
```

**Image Variants:**
- **`latest`** / **`<version>`** - Full image with browser support (~800MB)
- **`lite`** / **`lite-<version>`** - HTTP-only image (~200MB)

**Quick Docker Usage:**

```bash
# Run a spider project (mount your project directory)
docker run --rm -v ./my-spider:/app maxilr/swiftcrawl-runner:latest crawl example

# Use HTTP-only mode (lighter image)
docker run --rm -v ./my-spider:/app maxilr/swiftcrawl-runner:lite crawl example

# Export results to host
docker run --rm \
  -v ./my-spider:/app \
  -v ./output:/data \
  maxilr/swiftcrawl-runner crawl example -o /data/results.json

# Interactive development shell
docker run -it --rm -v ./my-spider:/app maxilr/swiftcrawl-runner bash
```

See the [Docker Usage](#docker-usage) section for more examples.

## Quick Start

### HTTP Mode (Fast & Stealthy)

```python
import asyncio
from swiftcrawl import SwiftCrawl

async def main():
    async with SwiftCrawl(method='http') as session:
        response = await session.get('https://api.example.com/data')
        data = response.json()
        print(data)

asyncio.run(main())
```

### Browser Mode (Full JS Support)

```python
import asyncio
from swiftcrawl import SwiftCrawl

async def main():
    async with SwiftCrawl(method='browser', headless=True) as session:
        response = await session.get('https://spa-website.com')

        # Parse with BeautifulSoup
        soup = response.soup()
        title = soup.find('title').string

        # Or use XPath
        tree = response.tree()
        links = tree.xpath('//a/@href')

        print(f"Title: {title}")
        print(f"Links: {links}")

asyncio.run(main())
```

## Usage Examples

### HTTP GET with Custom Headers

```python
async with SwiftCrawl(method='http') as session:
    response = await session.get(
        'https://api.example.com',
        headers={'Authorization': 'Bearer token123'}
    )
    print(response.json())
```

### HTTP POST

```python
async with SwiftCrawl(method='http') as session:
    response = await session.post(
        'https://api.example.com/submit',
        json={'key': 'value'}
    )
    print(response.status_code)
```

### Browser GET with Initial URL (Cookie Gathering)

```python
# Visit initial_url first to gather session cookies
async with SwiftCrawl(
    method='browser',
    initial_url='https://example.com/login',
    headless=True
) as session:
    # Subsequent requests will have cookies from initial_url
    response = await session.get('https://example.com/protected')
    print(response.text)
```

### Browser POST via fetch()

```python
# Uses page.evaluate() with fetch() for fast POST requests
async with SwiftCrawl(method='browser', headless=True) as session:
    response = await session.post(
        'https://api.example.com/endpoint',
        data={'username': 'test', 'password': 'secret'}
    )
    print(response.json())
```

### With Proxy

```python
# HTTP mode
async with SwiftCrawl(
    method='http',
    proxy='http://proxy.example.com:8080'
) as session:
    response = await session.get('https://example.com')

# Browser mode
async with SwiftCrawl(
    method='browser',
    proxy={'server': 'http://proxy.example.com:8080',
           'username': 'user',
           'password': 'pass'},
    geoip=True  # Auto-detect location from proxy
) as session:
    response = await session.get('https://example.com')
```

### Browser Warmup Function

The `warmup` parameter allows you to run a function after the browser initializes but before your main requests. This is perfect for login flows, gathering tokens, or setting up sessions.

```python
async def my_warmup(page):
    """
    Warmup function receives the Playwright page object.
    Use it to login, set cookies, gather tokens, etc.
    """
    await page.goto('https://example.com/login')

    # Set authentication cookies
    await page.evaluate('''() => {
        document.cookie = "auth_token=xyz123; path=/";
        document.cookie = "session_id=abc789; path=/";
    }''')

    print("Logged in and ready!")

# Use warmup with browser mode
async with SwiftCrawl(
    method='browser',
    warmup=my_warmup  # Executes before main requests
) as session:
    # Warmup already executed - we have auth cookies now
    response = await session.get('https://example.com/protected')
    print(response.text)
```

**Key Benefits:**
- Automatic login before scraping
- Gather CSRF tokens or API keys
- Set cookies and session data
- Execute complex multi-step setup
- Access full Playwright page object

## Scrapy-like Crawler & CLI

SwiftCrawl now ships with a Scrapy-inspired crawler stack and command-line interface.

### Defining a Spider

```python
from urllib.parse import urljoin

from swiftcrawl import Request, Spider


class QuotesSpider(Spider):
    name = "quotes"
    start_urls = ["https://quotes.toscrape.com"]
    method = "http"  # default, but you can override per domain/URL

    async def parse(self, response):
        soup = response.soup()
        for quote in soup.select(".quote"):
            yield {
                "text": quote.select_one(".text").text,
                "author": quote.select_one(".author").text,
            }

        next_link = soup.select_one(".next a")
        if next_link:
            yield Request(
                url=urljoin(response.url, next_link["href"]),
                callback=self.parse,
            )
```

### Running from Python

```python
import asyncio
from swiftcrawl import run_spider


items = run_spider(QuotesSpider)
print(items)
```

### Running from the CLI

Create `spiders/quotes_spider.py` containing your spider, then run:

```bash
# Print stats only
swiftcrawl crawl quotes

# Persist results
swiftcrawl crawl quotes -o output.jsonl

# Enable verbose logging / stack traces
swiftcrawl crawl quotes -o output.jsonl -v
```

The CLI automatically loads `settings.py` (if present), discovers spiders from the `spiders/` package, prints crawl statistics, and—when `-o/--output` is provided—writes scraped items to the specified `.json` or `.jsonl` file. `.json` outputs are standard JSON arrays (each item on a single line for easy diffs), while `.jsonl` outputs remain newline-delimited for streaming. Use `-v/--verbose` to see detailed request processing, item writes, and full error traces.

### Bootstrapping a Project

Need a fresh workspace? Use the built-in initializer:

```bash
swiftcrawl init my_scraper
cd my_scraper
swiftcrawl crawl example
```

`init` creates `spiders/`, a sample spider with Items, and a starter `settings.py` so you can begin crawling immediately.

### Item & Field API

Scraped data can be represented as structured Items with optional serialization hooks.

```python
from swiftcrawl import Item, Field


class QuoteItem(Item):
    text = Field()
    author = Field()
    tags = Field(default_factory=list, serializer=lambda values: ",".join(values))


class QuotesSpider(Spider):
    ...

    async def parse(self, response):
        for quote in response.soup().select('.quote'):
            yield QuoteItem(
                text=quote.select_one('.text').text,
                author=quote.select_one('.author').text,
                tags=[t.text for t in quote.select('.tag')],
            )
```

Items automatically convert to dictionaries (using field serializers) before the crawler writes them to disk.

### Response Parsing Methods

```python
async with SwiftCrawl(method='http') as session:
    response = await session.get('https://example.com')

    # Raw text
    html = response.text

    # JSON parsing
    data = response.json()

    # BeautifulSoup
    soup = response.soup()
    title = soup.find('title').string

    # lxml XPath
    tree = response.tree()
    paragraphs = tree.xpath('//p/text()')

    # Metadata
    print(response.status_code)
    print(response.headers)
    print(response.cookies)
    print(response.url)

    # When used in crawler context
    print(response.meta)      # Access request metadata
    print(response.request)   # Access original Request object
```

### Advanced Request Options

The `Request` class supports many advanced options for fine-grained control:

```python
from swiftcrawl import Request, Spider

class AdvancedSpider(Spider):
    name = "advanced"
    start_urls = ["https://example.com"]

    async def parse(self, response):
        # Priority requests (higher = processed first)
        yield Request(
            url="https://example.com/important",
            callback=self.parse,
            priority=10
        )

        # Skip deduplication (crawl same URL multiple times)
        yield Request(
            url="https://example.com/api",
            callback=self.parse,
            dont_filter=True
        )

        # Error handling with errback
        yield Request(
            url="https://example.com/fragile",
            callback=self.parse,
            errback=self.handle_error
        )

        # Force full browser navigation (instead of fetch)
        yield Request(
            url="https://spa.example.com",
            callback=self.parse,
            use_goto=True,
            wait_for_selector=".content-loaded",
            wait_for_timeout=5000  # milliseconds
        )

        # Pass metadata through request lifecycle
        yield Request(
            url="https://example.com/product/123",
            callback=self.parse_product,
            meta={"product_id": 123, "category": "electronics"}
        )

    async def parse_product(self, response):
        # Access metadata
        product_id = response.meta["product_id"]
        category = response.meta["category"]

        yield {
            "id": product_id,
            "category": category,
            "title": response.soup().find("h1").text
        }

    async def handle_error(self, request, exception):
        self.logger.error(f"Failed to fetch {request.url}: {exception}")
```

### Advanced Spider Features

#### Method Selection Per Domain/URL

Control which scraping method (http/browser) to use based on domain or URL pattern:

```python
class MixedSpider(Spider):
    name = "mixed"
    start_urls = ["https://example.com"]

    # Use different methods for different domains
    domain_methods = {
        "api.example.com": "http",      # Fast HTTP for APIs
        "spa.example.com": "browser",   # Browser for SPAs
    }

    # Use patterns for URL-based selection
    url_methods = {
        "*.json": "http",                    # HTTP for JSON endpoints
        "regex:.*dashboard.*": "browser",    # Browser for dashboard pages
    }

    async def parse(self, response):
        # Method is automatically selected based on URL
        yield {"data": response.json()}
```

#### Custom Settings Per Spider

Override global settings for specific spiders:

```python
class SlowSpider(Spider):
    name = "slow"
    start_urls = ["https://rate-limited-site.com"]

    # Spider-specific settings
    custom_settings = {
        "MAX_CONCURRENT": 2,           # Limit concurrency
        "REQUESTS_PER_SECOND": 0.5,    # One request every 2 seconds
        "RETRY_TIMES": 5,              # More retries
    }

    async def parse(self, response):
        yield {"title": response.soup().title.string}
```

#### Lifecycle Hooks

Spiders support lifecycle hooks for setup and teardown:

```python
class LifecycleSpider(Spider):
    name = "lifecycle"
    start_urls = ["https://example.com"]

    async def warmup(self, page):
        """Called before crawling starts (browser mode only)."""
        await page.goto("https://example.com/login")
        await page.fill("#username", "user")
        await page.fill("#password", "pass")
        await page.click("#login")
        self.logger.info("Logged in successfully")

    async def closed(self):
        """Called after crawling completes."""
        self.logger.info(f"Crawl finished. Scraped {len(self.items)} items")

    async def start_requests(self):
        """Override to customize initial requests."""
        for url in self.start_urls:
            yield Request(url, callback=self.parse, priority=5)

    async def parse(self, response):
        yield {"title": response.soup().title.string}
```

#### Access Browser Page in Spider

In browser mode, you can access the underlying Playwright page:

```python
class BrowserSpider(Spider):
    name = "browser"
    method = "browser"
    start_urls = ["https://example.com"]

    async def parse(self, response):
        # Access browser page directly
        page = self.page

        # Perform browser actions
        await page.click("button.load-more")
        await page.wait_for_selector(".new-content")

        # Get updated content
        new_response = await self.get(response.url)
        yield {"items": len(new_response.soup().find_all(".item"))}
```

## Configuration Options

### SwiftCrawl Constructor

```python
SwiftCrawl(
    method='http',           # 'http', 'browser', or 'auto' (future)
    proxy=None,              # Proxy URL or config dict
    headless=True,           # Browser headless mode
    block_images=True,       # Block images in browser
    humanize=None,           # Human-like behavior (0.0-2.0)
    initial_url=None,        # URL to visit first (browser only)
    warmup=None,             # Async function(page) for browser setup
    locale='en-US',          # Browser locale
    os=['windows', 'macos'], # OS fingerprint options
    geoip=False,             # Auto-geolocate from proxy
    timeout=30.0,            # Request timeout (HTTP)
    max_concurrent=10,       # Queue concurrency limit
)
```

### Crawler Settings (settings.py)

When using the Scrapy-inspired crawler framework, configure via `settings.py`:

```python
SETTINGS = {
    # Core Settings
    "METHOD": "http",                    # Default method: 'http', 'browser', 'auto'
    "SPIDERS_MODULE": "spiders",         # Directory containing spider files

    # Concurrency Control
    "MAX_CONCURRENT": 16,                # Global max concurrent requests
    "MAX_CONCURRENT_PER_DOMAIN": {},     # Per-domain limits: {"example.com": 2}

    # Rate Limiting
    "REQUESTS_PER_SECOND": None,         # Global rate limit (None = unlimited)
    "DOMAIN_DELAYS": {},                 # Per-domain delays: {"example.com": 1.0}

    # Auto-Throttle (Adaptive Rate Limiting)
    "AUTO_THROTTLE": False,              # Enable adaptive throttling
    "AUTO_THROTTLE_START": 1.0,          # Initial delay between requests
    "AUTO_THROTTLE_MAX": 60.0,           # Maximum delay
    "AUTO_THROTTLE_TARGET": 1.0,         # Target concurrency factor

    # Retry Logic
    "RETRY_ENABLED": True,               # Enable retry on failure
    "RETRY_TIMES": 2,                    # Max retry attempts per request

    # Deduplication
    "DEDUPLICATE": True,                 # Filter duplicate requests

    # Browser Settings (when METHOD='browser')
    "HEADLESS": True,                    # Run browser in headless mode
    "BLOCK_IMAGES": True,                # Block image loading for speed

    # Advanced Options
    "HTTP_OPTIONS": {},                  # Additional options for HTTP client
    "BROWSER_OPTIONS": {},               # Additional options for browser client
}
```

**Example: Rate-Limited Spider**

```python
# settings.py
SETTINGS = {
    "METHOD": "http",
    "MAX_CONCURRENT": 5,
    "REQUESTS_PER_SECOND": 2.0,          # 2 requests per second globally
    "DOMAIN_DELAYS": {
        "rate-limited-api.com": 2.0,     # 2 second delay for this domain
        "slow-site.com": 5.0,            # 5 second delay for this domain
    },
    "MAX_CONCURRENT_PER_DOMAIN": {
        "fragile-api.com": 1,            # Only 1 concurrent request
    },
    "RETRY_TIMES": 3,                    # Retry failed requests 3 times
}
```

**Example: Auto-Throttle Configuration**

Auto-throttle automatically adjusts request rate based on response times and server load:

```python
# settings.py
SETTINGS = {
    "METHOD": "http",
    "AUTO_THROTTLE": True,               # Enable adaptive throttling
    "AUTO_THROTTLE_START": 1.0,          # Start with 1 second between requests
    "AUTO_THROTTLE_MAX": 10.0,           # Max delay of 10 seconds
    "AUTO_THROTTLE_TARGET": 1.0,         # Aim for 1 concurrent request per target
    "MAX_CONCURRENT": 32,                # Overall concurrency limit
}
```

### HTTP Mode Options (BrowserForge + httpx)
- Generates realistic browser headers automatically
- Rotates fingerprints between requests
- Supports all standard httpx parameters

### Browser Mode Options (Camoufox)
- **headless**: Run in headless mode (default: True)
- **block_images**: Block image loading for speed (default: True)
- **humanize**: Enable human-like cursor movement (0.0-2.0)
- **initial_url**: Navigate here first to collect cookies/session
- **warmup**: Async function that receives the page object for setup (login, cookies, etc.)
- **geoip**: Auto-detect geolocation from proxy IP
- **locale**: Browser locale (default: 'en-US')
- **os**: List of OS to randomly choose from

## Parameter Validation

SwiftCrawl validates parameter compatibility and warns you about configuration mistakes:

### Errors (ValueError)
Raised when parameters are fundamentally incompatible:

```python
# ERROR: warmup requires browser mode
session = SwiftCrawl(method='http', warmup=my_warmup)
# ValueError: warmup parameter is only supported for 'browser' and 'auto' methods.
```

### Warnings (UserWarning)
Issued when parameters will be ignored:

```python
# WARNING: browser params with HTTP mode
session = SwiftCrawl(
    method='http',
    headless=False,  # Ignored in HTTP mode
    humanize=1.5     # Ignored in HTTP mode
)
# UserWarning: Browser-only parameters ['headless', 'humanize'] are ignored in HTTP mode.

# WARNING: timeout with browser mode
session = SwiftCrawl(method='browser', timeout=10.0)
# UserWarning: HTTP timeout parameter is ignored in browser mode.
```

This helps catch configuration mistakes early and ensures you understand which parameters are being used.

## Docker Usage

SwiftCrawl provides production-ready Docker images with two variants:

### Image Variants

| Variant | Size | Use Case | Includes |
|---------|------|----------|----------|
| **`latest`** / **`<version>`** | ~800MB | Full browser automation | Camoufox, Playwright, Chromium |
| **`lite`** / **`lite-<version>`** | ~200MB | HTTP-only scraping | httpx, BrowserForge |

### Running Spiders with Docker

**Basic spider execution:**

```bash
# Create a spider project locally
swiftcrawl init my-spider
cd my-spider

# Run the spider in a container (full browser support)
docker run --rm -v "$(pwd):/app" maxilr/swiftcrawl-runner:latest crawl example

# Use lite version for HTTP-only spiders (faster, smaller)
docker run --rm -v "$(pwd):/app" maxilr/swiftcrawl-runner:lite crawl example
```

**Export results to host:**

```bash
# Create output directory
mkdir output

# Run spider and save results
docker run --rm \
  -v "$(pwd):/app" \
  -v "$(pwd)/output:/data" \
  maxilr/swiftcrawl-runner:latest \
  crawl example -o /data/results.jsonl
```

**Interactive development:**

```bash
# Start a bash shell in the container
docker run -it --rm -v "$(pwd):/app" maxilr/swiftcrawl-runner bash

# Inside container, you can:
# - Edit files with vi/nano
# - Run swiftcrawl commands
# - Test individual scripts
```

**With proxy:**

```bash
# HTTP mode with proxy (environment variable)
docker run --rm \
  -v "$(pwd):/app" \
  -e HTTP_PROXY=http://proxy.example.com:8080 \
  maxilr/swiftcrawl-runner:lite crawl example

# Browser mode needs proxy in settings.py or spider code
```

**Pin specific version:**

```bash
# Use a specific version tag
docker run --rm -v "$(pwd):/app" maxilr/swiftcrawl-runner:0.1 crawl example

# Or lite variant with version
docker run --rm -v "$(pwd):/app" maxilr/swiftcrawl-runner:lite-0.1 crawl example
```

### Building Custom Images

If you need to extend the base image with additional dependencies:

```dockerfile
# docker/Dockerfile.custom
FROM maxilr/swiftcrawl-runner:latest

# Install additional Python packages
RUN uv pip install pandas numpy

# Or install system packages
RUN apt-get update && apt-get install -y git && rm -rf /var/lib/apt/lists/*

# Copy your project
COPY . /app
WORKDIR /app

# Run your spider
CMD ["crawl", "myspider"]
```

Build and run:

```bash
docker build -t my-custom-scraper -f docker/Dockerfile.custom .
docker run --rm my-custom-scraper
```

### Docker Compose Example

```yaml
# docker-compose.yml
version: '3.8'

services:
  scraper:
    image: maxilr/swiftcrawl-runner:latest
    volumes:
      - ./my-spider:/app
      - ./output:/data
    command: crawl example -o /data/results.jsonl
    environment:
      - PYTHONUNBUFFERED=1

  # HTTP-only scraper (lighter)
  scraper-lite:
    image: maxilr/swiftcrawl-runner:lite
    volumes:
      - ./my-spider:/app
      - ./output:/data
    command: crawl api-spider -o /data/api-results.json
```

Run with:

```bash
docker-compose up scraper
# or
docker-compose up scraper-lite
```

## Testing

```bash
# Run fast, offline-safe suite
uv run pytest

# Include network + browser integration tests (needs internet & Playwright)
SWIFTCRAWL_RUN_NETWORK_TESTS=1 uv run pytest
```
