soupstars 2.11.21

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

The client is also available as a docker image.

docker pull soupstars/client

Building a parser

Create a new parser using the soupstars command. The create command will use a template parser.

soupstars create -m myparser.py

Parsers are simple python modules.

cat myparser.py

Notice that the only set up required is the special parse decorator and a variable named url for the web page you want to parse.

from soupstars import parse

url = "https://corbettanalytics.com/"

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

You can test that the parser functions correctly.

soupstars run -m myparser.py

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

More documentation is available here.

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/*
