Easily add MySQL database to your Kemal application.

Installation

Add this to your application's shard.yml:

dependencies:
  kemal-mysql:
    github: sdogruyol/kemal-mysql

Usage

This middleware adds MySQL connection pool to Kemal as a middleware.

require "kemal"
require "kemal-mysql"

CONN_OPTS = {
  "host" => "127.0.0.1",
  "user" => "root",
  "password" => "",
  "db" => "your_db"
}

mysql_connect CONN_OPTS, 25, 0.1

# Make sure to yield `env`.
get "/" do |env|
  env.content_type = "application/json"
  users = conn.query("SELECT * FROM users")
  # Release the connection after you are done with exec
  release
  # Renders the users as JSON
  users
end

You can configure the connection pool capacity and timeout like:

mysql_connect CONN_OPTS, capacity: 10, timeout: 0.1

The default value for connection pool capacity is 25 and timeout is 0.1.
