soupstars 2.11.24

Declarative web parsers

Soup Stars

Soup Stars is a framework for building web parsers with Python. It is designed to make building, deploying, and scheduling web parsers easier by simplifying what you need to get started.

Quickstart

pip install soupstars

Creating a parser

New parsers are created by typing soupstars create into a terminal, and supplying the name of a python module.

soupstars create myparser.py

Soup Stars will use a template parser to help you get started. This example creates a parser that extracts headlines from articles on the New York Times website.

from soupstars import data, follow

url = "https://www.nytimes.com"

@follow
def follow(url):
    return (url.domain == "www.nytimes.com") and (url.match("\d{4}\/\d{2}\/\d{2}"))

@parse
def h1(soup):
    return soup.h1.text

You can test that the parser functions correctly.

soupstars run myparser

Use soupstars --help to see a full list of available commands.

Development

Start the docker services.

docker-compose up -d

Set up the containers.

docker-compose exec web flask s3 mb soupstars-archive
docker-compose exec web flask db upgrade
docker-compose exec web flask seed schedules
docker-compose exec web flask seed plans
docker-compose exec web flask seed user
docker-compose exec web flask seed parsers

Run the tests.

docker-compose run --rm client pytest -vs

Releasing

New tags that pass on CI will automatically be pushed to docker hub.

To deploy to PyPI requires manually running the following commands.

pip3 install twine
python3 setup.py sdist bdist_wheel
twine upload dist/*
