Rack::GridFS

Rack:GridFS is a Rack middleware for creating HTTP endpoints for files stored in MongoDB’s GridFS. You can configure a prefix string which will be used to match the path of a request and create an id for looking up the file in the GridFS store.

For example,

GET '/gridfs/someobjectid'

If the prefix is “gridfs”, then the key will be be “someobjectid”.

Installation

gem install jnunemaker--rack-gridfs

require 'rack/gridfs'
use Rack::GridFS, :hostname => 'localhost', :port => 27017, :database => 'test', :prefix => 'gridfs'

  • hostname: the hostname/IP where the MongoDB server is running. Default ‘localhost’.

  • port: the port of the MongoDB server. Default 27017.

  • database: the MongoDB database to connect to.

  • prefix: a string used to match against incoming paths and route to through the middleware. Default ‘gridfs’.
