scrapy-do 0.5.0

A daemon for scheduling Scrapy spiders

Scrapy Do is a daemon that provides a convenient way to run Scrapy spiders. It can either do it once - immediately; or it can run them periodically, at specified time intervals. It’s been inspired by scrapyd but written from scratch. It comes with a REST API, a command line client, and an interactive web interface.

Quick Start

• Install scrapy-do using pip:

  $ cd quotesbot
  $ scrapy-do-cl push-project

  | toscrape-css   |
  | toscrape-xpath |
  +----------------+

• Schedule some jobs:

  $ scrapy-do-cl schedule-job --project quotesbot \
      --spider toscrape-css --when 'every 5 to 15 minutes'
  +--------------------------------------+
  | identifier                           |
