duct.module.datomic CircleCI

A Duct module that adds Integrant keys for a Datomic database connection and Ragtime migrations to a configuration.

Installation

To install, add the following to your project :dependencies:

[hden/duct.module.datomic "0.5.7"]

Usage

To add this module to your configuration, add the :duct.module/sql key to your config.edn file:

:duct.module/datomic {:server-type :ion
                      :region      "us-east-1"
                      :system      "mbrainz-stu"
                      :endpoint    "http://entry.mbrainz-stu.us-east-1.datomic.net:8182"
                      :proxy-port  8182
                      :database    "datomic-docs-tutorial"}

;; Read configurations from the AWS SSM
;; Assumes that parameters are stored under `/datomic-shared/(env)/(app-name)/`
;; See https://docs.datomic.com/cloud/ions/ions-reference.html#parameters-example
[:duct.reader.ion/get-param :my-app.params/my-param]
{:key      "my-param"
 :default  "foobar"
 :logger   #ig/ref :duct/logger}

dev-local

You can develop and test applications with minimal connectivity and setup by using the dev-local tool. Override the connection by setting the :duct.database/datomic key in the dev.edn.

See https://docs.datomic.com/cloud/dev-local.html

:duct.database/datomic
{:server-type :dev-local
 :storage-dir :mem
 :system      "mbrainz-stu"
 :database    "datomic-docs-tutorial"}

Integrant Keys

When prepped, the module will compile the following Integrant keys into your config:

:duct.database/datomic {}
:duct.migrator.ragtime/datomic {:database #ig/ref :duct.database/datomic
                                :logger #ig/ref :duct/logger
                                :migrations []}

These defaults can be (selectively) overridden through custom :duct.database/datomic and :duct.migrator.ragtime/datomic keys in your duct profiles.
