Quick Start

Installation

pip install scrapy-poet

Requires Python 3.8+ and Scrapy >= 2.6.0.

Usage in a Scrapy Project

Add the following inside Scrapy’s settings.py file:

DOWNLOADER_MIDDLEWARES = {
    "scrapy_poet.InjectionMiddleware": 543,
    "scrapy.downloadermiddlewares.stats.DownloaderStats": None,
    "scrapy_poet.DownloaderStatsMiddleware": 850,

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.
