Installation

To install, add the following to your project dependencies:

[hden/duct.database.datomic "0.1.0"]

Usage

This library provides two things: a Boundary record that holds a database client and a database connection, and a multimethod for :duct.database/datomic that initiates a database spec into the Boundary.

;; https://docs.datomic.com/client-api/datomic.client.api.html#var-client
{:duct.database/datomic {:server-type :ion
                         :region "AWS region"
                         :system "your system name"
                         :endpoint "http://entry.{{system}}.{{region}}.datomic.net:8182"
                         :proxy-port 8182
                         :database "db-name"}}

When you write functions against the database, consider using a protocol and extending the Boundary record. This will allow you to easily mock or stub out the database using a tool like Shrubbery.
