Usage

Docker

1. create a folder for the app and change your workdir: mkdir craigscraper; cd craigscraper
2. create a notification file using the instructions below vi notifications.yaml
3. prepare a .env file using the .env_template as model. Remember to uncomment the last two lines to allow data persistance
4. run docker: docker run --env-file ./craigscraper/.env -v ./craigscraper:/persist ghcr.io/porelli/craigscraper:main

if you want to examinate the database

• docker run -it --rm -p 8080:8080 -v ./craigscraper:/data -e SQLITE_DATABASE=rents.db coleifer/sqlite-web

Local or dev

1. clone the package
2. copy .env_template to .env
3. replace values in .env
4. create venv: python3 -m venv .venv
5. activate venv: source .venv/bin/activate
6. install dependencies: pip3 install -r requirements.txt
7. profit: scrapy crawl rent

Periodic scan

• suppress the notification test in the .env file using SUPPRESS_TEST_NOTIFICATION='True'
• specify the scan interval in the .env file using MINUTES_INTERVAL
• run: python3 main.py

Caveats (PRs are welcome!)

• currently it works only for Vancouver, BC
• code is not very organized and does not follow all the scrapy best practices

Notifications

By default, the script will try to send a desktop notification. A first notification is sent at the beginning as a test. Subsequent notifications are sent when new apartments appear in the search on there is a price change.

You can override the default behavior specifying your own notification provider(s) with an apprise compatible configuration file and using the -a notifications_file=<NOTIFICATION_FILE> CLI option or via ENV NOTIFICATION_FILE.

Please note, that for notifications to work on Mac or Windows, you may need to install additional packages. If you experience any errors with this, please refer to the apprise wiki.

MacOS

brew install terminal-notifier

Windows

pip install pywin32
