to-jdbc-uri

Code at GitHub Clojars Build Status Join the chat at https://gitter.im/carouselapps/to-jdbc-uri

Many libraries starting with clojure.java.jdbc and libraries that use clojure.java.jdbc internally expect a JDBC URI to connect to the database, but your environment might be giving you the database specs in a different format. to-jdbc-uri is designed to take the database credentials in any format and, as long as it's possible, generate a valid JDBC URI. Currently supported:

  • PostgreSQL (Heroku, RedHat OpenShift and others)
  • MySQL

Support for other formats, databases, environments is welcome.

The code in this library is actually trivial but if you need to perform this task and search for solutions you'll find lots of different snippets of code, some which work in some environments and not others. Even if you end up not using this library but copying and pasting the code it is better to have a canonical place for this code to exist.

Usage

In your project.clj include the dependency:

Clojars Project

and then call it like this:

(to-jdbc-uri.core/to-jdbc-uri your-non-jdbc-url)

for example:

(to-jdbc-uri "postgres://username:password@hostname/dbname")

which will output:

"jdbc:postgresql://hostname/dbname?user=username&password=password"

It is safe to feed JDBC URIs to this library, they'll be left untouched. For more examples, you might want to look into the tests, which are very simple.

Note: to-jdbc-uri up to version 0.3.0 was not in the com.carouselapps group, from 0.4.0 it'll be in the com.carouselapps groups. If you are using this jar, you can and should switch from [to-jdbc-uri "0.3.0"] to [com.carouselapps/to-jdbc-uri "0.4.1"] or the latest version.
