Build a Price Tracker with Crawlee and Apify

Описание и применение

Руководство по созданию трекера цен с помощью Crawlee для Python и Apify. Описывается процесс настройки скрапера, извлечения данных о продукте, отправки email-уведомлений при снижении цены и развертывания решения в облаке Apify.

Задача

Manually checking product prices is inefficient. Users need an automated way to monitor specific products for price drops and receive immediate notifications.

Результат

A fully functional Apify Actor that scrapes product details, exports data in various formats, and sends email alerts when prices drop below a set threshold.

Рабочий процесс

• Install Apify CLI and create a new project using the 'Python and Crawlee + BeautifulSoup' template.
• Configure the crawler to target a specific product URL (e.g., Raspberry Pi 5 on Central Computer).
• Implement CSS selectors to extract product name and price (handling currency symbols and data attributes).
• Define a price threshold and integrate the 'Send Email' Actor to trigger alerts when the price drops below the threshold.
• Authenticate with Apify using an API token to enable email sending capabilities.
• Test the script locally using 'apify run --purge'.
• Deploy the actor to the Apify cloud using 'apify push'.
• Configure the actor input and schedule runs in the Apify dashboard.
