Software is easy until you need to scale. But luckily for you, JavaScript and frontend developers have a clear advantage when moving to event-driven architectures and microservices. Events on clicks and blurs were your training wheels. Asynchronous is a given. You may have used a state management framework like Redux or Vuex. You are destined for this.

To demonstrate, we'll examine a full stack JavaScript upload service written with Vue, Express and RabbitMQ. Ignore the frameworks. We'll focus on the messaging and state patterns that trip up many developers, preventing them from building true microservices. At the end of the talk, you will understand how to chunk file uploads on the front- and backend for happy users and developers.
