How to resolve promises when using app with REPL

I've got a basic Node webserver (Koa.js + a ORM). I like to start it with a REPL meaning I can use my app like a CLI-tool.

All my queries return Promises but I don't know how I can resolve them in the REPL. How can I resolve them?

For example the following code (fetch() queries the database and returns a promise) gives only this output Promise {_bitField: 4325376, _fulfillmentHandler0: undefined, _rejectionHandler0: undefined …}

Transaction.where('reference', '1').fetch().then((res) => return res)
