Utilities for running scrapy on heroku
A package to assist with running scrapy on heroku. This is accomplished by providing a custom application configuration at scrapy_heroku.app.application that launches the scrapyd web service using the PORT environment variable and a multi-process work queue implemented on a Postgres database specified by the DATABASE_URL environment variable.
Create a git repo that has a scrapy project at the root (scrapy.cfg should be at the top level). Edit your scrapy.cfg to include the following:
[scrapyd] application = scrapy_heroku.app.application [deploy] url = http://<YOUR_HEROKU_APP_NAME>.herokuapp.com:80/ project = <YOUR_PROJECT_NAME> username = <A_USER_NAME> password = <A_PASSWORD>
Add a requirements.txt file that includes scrapy-heroku in it. It is strongly recommended that you version pin scrapy-heroku as well as the version of scrapy that your project is developed against (pip freeze > requirements.txt). Finally create a Procfile that consists of:
web: scrapy server
Make sure you have a postgres database that has been promoted to DATABASE_URL
