Community Event

Hey Berlin devs, long time no see! You're invited to the upcoming gathering of our community on February 19 where we'll show you how to learn more about React by taking it apart and putting it back together, and also how to migrate a big project from a legacy tech stack to a new and shiny one.

Driving Migration

by Alex Suevalov

A path from point A to point B is not always easy and straightforward. You might know it, especially, if you ever migrated a big project from a legacy tech stack to a new and shiny one. In this talk, Aleksandr will share a journey of building a tool that helps Contentful to track the adoption of a new tech stack and design system.

More details: Migration of a massive project from one tech framework to another (in our case Angular 1.x to React) is a hot topic for a lot of companies. In his talk, Aleksandr will show a tool and ideas behind it that helped Contentful to facilitate migration, gave better visibility and changed his team's habits.
