autoscout24-vizualizer

AutoScout vizualizer is composed of a crawler that periodically scraps and stores into database the cars returned by a set of search parameters, and a Next.js webapp that allows visualizing the stored data.

Install

pip install -r requirements.txt

Create an .env file and set the PGSQL_URL variable to point to your PostgreSQL database. Also create a free resend.com API key RESEND_API_KEY to be able to receive results by email.

Run

Create as many *.env file as you want in the searches directory and run the extraction with the following command:

scrapy crawl search -a config_file=rs6.env
