``scrapy-poet`` is the `web-poet`_ Page Object pattern implementation for Scrapy.

``scrapy-poet`` allows to write spiders where extraction logic is separated from the crawling one.

With ``scrapy-poet`` is possible to make a single spider that supports many sites with

different layouts.

Quick Start

***********

Installation

============

.. code-block::

    pip install scrapy-poet

Requires **Python 3.9+** and **Scrapy >= 2.6.0**.

Usage in a Scrapy Project

=========================

Add the following inside Scrapy's ``settings.py`` file:

.. code-block:: python

    DOWNLOADER_MIDDLEWARES = {

        "scrapy_poet.InjectionMiddleware": 543,

        "scrapy.downloadermiddlewares.stats.DownloaderStats": None,

        "scrapy_poet.DownloaderStatsMiddleware": 850,

    }

    SPIDER_MIDDLEWARES = {

        "scrapy_poet.RetryMiddleware": 275,

    }

    REQUEST_FINGERPRINTER_CLASS = "scrapy_poet.ScrapyPoetRequestFingerprinter"

Developing

==========

Setup your local Python environment via:

1. `pip install -r requirements-dev.txt`

2. `pre-commit install`

Now everytime you perform a `git commit`, these tools will run against the

staged files:

* `black`

* `isort`

* `flake8`

You can also directly invoke `pre-commit run --all-files` or `tox -e linters`

to run them without performing a commit.
