RedisJSON Ruby Client

rejson-rb is a package that allows storing, updating and querying objects as JSON documents in a Redis database that is extended with the ReJSON module. The package extends redis-rb's interface with ReJSON's API, and performs on-the-fly serialization/deserialization of objects to/from JSON.

Add this line to your application's Gemfile:

gem 'rejson-rb'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install rejson-rb

Make sure you have loaded rejson module in redis.conf

require 'rejson'

rcl = Redis.new # Get a redis client

# Get/Set/Delete keys
obj = {
        'foo': 42,
        'arr': [nil, true, 3.14],
        'truth': {
          'coord': "out there"
        }
      }

rcl.json_set("root", Rejson::Path.root_path, obj)
# => "OK" 

rcl.json_set("root", Rejson::Path.new(".foo"), 56)
# => "OK" 

rcl.json_get "root", Rejson::Path.root_path
# => {"foo"=>56, "arr"=>[nil, true, 3.14], "truth"=>{"coord"=>"out there"}}

rcl.json_del "root", ".truth.coord"
# => 1

# Use similar to redis-rb client
rj = rcl.pipelined do
  rcl.set "foo", "bar"
  rcl.json_set "test", ".", "{:foo => 'bar', :baz => 'qux'}"
end
# => ["OK", "OK"] 

Path to JSON can be passed as Rejson::Path.new("<path>") or Rejson::Path.root_path. <path> syntax can be as mentioned here.
