Runtime exception with lein run (HikariPool) guestbook-sente

[paulrd]

I'm getting the following error when I do lein run in the guestbook-sente project:

The reason is that the database configuration isn't available in the project. I've added example configuration so that it runs out of the box. You have to follow these steps to get it running:

• run migrations: lein run migrate
• compile ClojureScript lein cljsbuild once
• start the server lein run
