Evolving code at scale

About this presentation

When you first start building a web application, it's easy to write code and pull in the dependencies you need. What happens in 5 years (or 5 weeks) when the industry has decided what once was a super useful library is causing enterprise computers to become fire hazards? In this talk, we'll cover how we can modernise our code to the new dependencies we want, build tools and processes to migrate to new code, and avoid breaking things without moving too slowly.
