As you can see, all the jwt properties are self-contained except expiration info. Method isExpired uses ReactiveMongo, which always returns a Future. To make things even more complex, I use this jwt in...

In Scala, it's said that a future returns "eventually." The following examples show a variety of ways to create futures and work with their eventual results. Run one task, but block.

A Scala Future is used to create a little pocket of concurrency that you use for one-shot needs. To demonstrate how this works, let's start with an example of a Future in the Scala REPL.

This video introduces you to the concept of Futures and how you can create a scala.concurrent.Future object.

Scala Future incorporates recover that acts as a back-up future when an error occurs. This allows the future composition to finish even with failures. To illustrate, consider this code

This Scala Tutorial is a step by step beginner's guide to help you learn how use Scala futures to perform asynchronous non blocking operations in parallel.

The Scala Future API provides a comprehensive set of functions for writing concurrent, asynchronous code. By design, Scala is a functional programming language with an inherent emphasis on...

Scala Future is eager by nature. This means that Future execution starts in the very moment it has been defined. It's not a problem if you have no side effects inside your Futures.
