How we migrated a complex JavaScript application to ClojureScript step-by-step - Alex King

Alex King explains how Exoscale migrated a complex JavaScript application to ClojureScript step-by-step using a data-driven approach.

As software evolves along with the languages and frameworks it is built upon, it’s easy to create a monster. This is the tale of tackling complexity at the heart of Exoscale, and how a data-driven approach with ClojureScript enabled us to seamlessly replace a JavaScript app without user outage. About the speaker: Alex King is a software engineer from the UK, currently based in Switzerland with Exoscale. He is passionate about delivering clean, well tested code, that is easy for others to understand. He is well experienced with over 15 years of software development, and adept at bridging the gap between the front-end and back-end teams. He was responsible for large rewrites of core architecture behind the BBC Sport and BBC News platforms, and worked as a consultant for JUXT, where he helped to develop a large Clojure(script) application used by traders at Credit Suisse, along with many years of Scala development before finding a home with Clojure. Away from the day job he can be found enjoying hammock time up in the mountains, or on stage in a dive bar with a guitar in hand.
