Elster

Elster is a streaming JSON encoder written in pure ruby.

Installation

Add this line to your application's Gemfile:

gem 'elster'

And then execute:

$ bundle

Or install it yourself as:

$ gem install elster

Usage

output = StringIO.new
json = Elster::Streamer.new(output)
json.key(:name, "George")
json.key(:kids) do
  json.add("Job")
  json.add("Buster")
end
json.close

puts output.string
# {"name":"George","kids":["Job","Buster"]}

With Rails

You can use Elster with rails by naming templates with the .json.elster extension. When used as a rails template simply reference the implicit json object. For example:

json.key(:name, "George")
json.key(:kids) do
  json.add("Job")
  json.add("Buster")
end
