Sinatra::JSONAPI

This is an extension for Sinatra that makes the Base class return JSON for 404 and 500 errors, and gives you api_response and api_error for quick JSON responses.

Caveats

Does not automatically try to convert response. You need to use api_response or api_error, or halt with proper JSON like such:

get '/ping' do
  halt {response: 'pong'}.to_json
end

Installation

Add this line to your application's Gemfile:

gem 'sinatra-jsonapi', require: 'sinatra/jsonapi'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sinatra-jsonapi

Usage

For classy apps:

require 'sinatra'
require 'sinatra/jsonapi'

class MyCoolAPI < Sinatra::Base
  register Sinatra::JSONAPI

  get '/hello' do
    api_response response: 'world!'
  end

  # Returns:
  # {"response":"world!"}

  get '/break' do
    api_error :your_error_type, 'human readable version of error message'
  end

  # Returns:
  # {"error":{"error_type":"your_error_type", "message":"human readable version of your error message"}}
end

For classic style apps (no class), registration of the extension happens automatically:

require 'sinatra'
require 'sinatra/jsonapi'

get '/hello' do
  api_response response: 'world!'
end
