We've had a few presentations on using re-frame and continue to get many questions on this fantastic tool. There is a lot to learn but you will be rewarded when building single page apps. So this month our own Matthew Lyon will present:

Constructing Interfaces with re-frame

I’ve talked to many clojurists who are curious about front-end programming but don’t know where to start. They haven’t done front-end work before, they’re unfamiliar with JavaScript or React, and they don’t understand how those pieces fit together. I’ll walk through what a ClojureScript development environment looks like; what makes front-end programming different and how React, reagent, and re-frame fit into this; how to create views with Reagent; how to manage state and the outside world with re-frame; and how to effectively debug your front-end code.

Matthew Lyon has been building the front- and back-ends for web applications for over twelve years, and with Clojure for three years. He enjoys creating interfaces for helping people work through complex interactions.

Much has been said about building re-frame applications in the small, but how well do these same techniques perform building large applications? In practice, our team found traditional approaches to events and state management led to highly-coupled code that was difficult to maintain and test.

In this talk we'll explore why this happens and some simple techniques you can use to create more re-usable re-frame code without boilerplate or any 3rd party libraries.

Biography Ryan is a Clojure developer, author, and founder of Homegrown Labs (http://homegrownlabs.ca ), a consultancy and education company based in Winnipeg, Canada.

Since April 2017, Ryan & Homegrown have been working with Funding Circle building rich admin applications using ClojureScript & re-frame.

Beyond consulting, Ryan organizes Clojure Remote (http://clojureremote.com )–an online conference focussed on remote Clojure & ClojureScript developers. Keep an eye out for ClojureScript Days coming Summer of 2018.

Come join us in an evening of stimulating discussion where we explore an approach in developing an event-sourced, CQRS-based real time system. We’ll look at the reframe inspired events system on the server side, as well as how the interceptor pattern can be used to achieve a clean implementation.
