kemal-pg

Easily add Postgresql database to your Kemal application.

Installation

Add this to your application's shard.yml:

dependencies:
  kemal-pg:
    github: sdogruyol/kemal-pg

Usage

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

require "kemal"
require "kemal-pg"

pg_connect "postgres://user@host:5432/your_db"

# Make sure to yield `env`.
get "/" do |env|
  users = conn.exec("SELECT * FROM users")
  # Release the connection after you are done with exec
  release
  "Hello from postgresql"
end

You can configure the connection pool capacity and timeout like:

pg_connect "postgres://user@host:5432/your_db", capacity: 10, timeout: 0.1

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