Scrapy beyond the first steps

This the Scrapy project I'm basing my talk at Python Brasil 2018

Most of the components (pipelines, item exporters, middlewares) are enabled by default.

Install requirements:

$ virtualenv -p python3 venv
$ source venv/bin/activate
$ pip install -r requirements.txt

Run some spiders

$ scrapy crawl books -o books.json

$ cat books.json | jq .
[
  {
    "price": 51.7,
    "title": "A Light in the Attic",
    "url": "http://books.toscrape.com/catalogue/a-light-in-the-attic_1000/index.html"
  },
  {
    "price": 47.82,
    "title": "Sharp Objects",
    "url": "http://books.toscrape.com/catalogue/sharp-objects_997/index.html"
  },
...

$ scrapy crawl temperature -o temperature.json

$ cat temperature.json | jq .
[
  {
    "destination": "115.594409475582 Fahrenheit",
    "source": "46.441338597545496 Celsius"
  },
  {
