Precacher

Precacher is written to update static files based on Ruby code. In the future it could be expanded to work in memcache, and other caching solutions.

in your Gemfile:

gem "precacher"

and bundle install!

    val = Precacher.file_cache("/path/to/file") do
      # if data generated is the same, file is not updated.
      MyCreateFileData('file')
    end
    # val is true if their was a write, and false if not.

I had a simple HTML/JS project that needs to possibly update a JSON file anytime in 1-90 days windows.

I did not want an entire RAILS stack for just this part, but I did want to use other ruby gems.

So I just updated the static files via a cron job every hour, only if they were updated.
