WebMinion is a metadata-driven browser automation library. Instead of writing a custom bot with lots of code, you can write a JSON configuration and give it to WebMinion to run instead. You can use webdrivers like Mechanize, Capybara/Selenium (TODO) and Capybara/PhantomJS (TODO).

NOTE The public API is currently unstable and subject to change.

Installation

Add this line to your application's Gemfile:

gem 'web_minion'

And then execute:

$ bundle

Or install it yourself as:

$ gem install web_minion

Usage

web_minion = WebMinion::Flow.build_via_json(File.read("./test/test_json/test_json_one.json"))
web_minion.perform
