​
Define the environment

First, we’ll define our environment:

app.py
from beam import App, Runtime, Image


app = App(
    name="web-scraper",
    runtime=Runtime(
        cpu=1,
        memory="8Gi",
        image=Image(
            python_version="python3.8",
            python_packages=["bs4", "transformers", "torch"],
        ),
    ),
)

​
Write scraping logic

Now, we’ll write logic to scrape the headlines from The New York Times.

In order to run this on Beam, we add an @app.run() decorator to the function:

@app.run()
def scrape_nyt():
    ...

​
Running the scraper

Now, we’re ready to run our code using Beam. In your terminal, run:

beam run your_file.py:scrape_nyt

You should see the headlines and the detected sentiment of each:

(.venv) beta9@MacBook-Air-2 web-scraping % beam-stage run app.py:scrape_nyt
