Learn how to scrape websites with Python, Selenium, Requests HTML, Celery, FastAPI, & NoSQL.
Here's what each tool is used for:
- Python 3.9 download - programming the logic.
- AstraDB sign up - highly perfomant and scalable database service by DataStax. AstraDB is a Cassandra NoSQL Database. Cassandra is used by Netflix, Discord, Apple, and many others to handle astonding amounts of data.
- Selenium docs - an automated web browsing experience that allows:
- Run all web-browser actions through code
- Loads JavaScript heavy websites
- Can perform standard user interaction like clicks, form submits, logins, etc.
- Requests HTML docs - we're going to use this to parse an HTML document extracted from Selenium
- Celery docs - Celery providers worker processes that will allow us to schedule when we need to scrape websites. We'll be using redis as our task queue.
- FastAPI docs - as a web application framework to Display and monitor web scraping results from anywhere
This series is broken up into 4 parts:
- Scraping How to scrape and parse data from nearly any website with Selenium & Requests HTML.
- Data models how to store and validate data with
cassandra-driver,pydantic, and AstraDB. - Worker & Scheduling how to schedule periodic tasks (ie scraping) integrated with Redis & AstraDB
- Presentation How to combine the above steps in as robust web application service
