This is a demo repository to show how to build and distribute really fast JSON API apps with MRuby, Rack, Redis and H2O.

Explanation

For a full explanation of how this works, please read this article: 25,000+ Req/s for Rack JSON API with MRuby.

Prerequisites

• gcc
• cmake
• wrk (for benchmarks)
• Redis

Setup

➜ git clone https://github.com/jodosha/mruby-rack-json-api.git
➜ cd mruby-json-api
➜ bin/setup

This will start Redis and H2O.

There are two endpoints available:

• http://localhost:8080/hardcoded
• http://localhost:8080/json_api
