Duct database.datalevin

Integrant methods for connecting to a Datalevin database from the Duct framework. These methods can also be used outside Duct in any Integrant application.

Installation

Add the following dependency to your deps.edn file:

org.duct-framework/database.datalevin {:mvn/version "0.1.1"}

Or to your Leiningen project file:

[org.duct-framework/database.datalevin "0.1.1"]

Usage

This library provides the :duct.database/datalevin Integrant key, which takes a mandatory :dir option:

{:duct.database/datalevin {:dir "./datalevin"}}

This can be either a directory path, or a dtlv connection URI string. You can also specify a schema with the :schema key:

{:duct.database/datalevin
 {:dir "./datalevin"
  :schema {:user/name {:db/valueType :db.type/string
                       :db/unique :db.unique/identity}}}}

Finally, you can also use any of the options that the datalevin.core/create-conn function takes. For example:

{:duct.database/datalevin
 {:dir "./datalevin"
  :schema {:user/name {:db/valueType :db.type/string
                       :db/unique :db.unique/identity}}
  :closed-schema? true}}
