The How, What and Why of migrating to ReactJS

May 2017

The application I look after at work is a large ticketing platform that was written using Angular 1 and has not been maintained. With the new release of Angular 2, we made the decision to migrate off Angular and onto React.

In this talk I’ll discuss why we did this (without criticising Angular, it has served us well) and how we’re migrating in small chunks. A big rewrite was off the cards; this application is business critical and as such we can’t afford to not be able to fix existing bugs or quickly add features because we’re rewriting. Instead, we’ve split the work down into many small pieces that we can tackle one at a time.

I’ll go through some code examples and talk not only about the benefits but the negatives too, because it’s not all been plain sailing. We’ll see how React’s approach and characteristics make it very adaptable and we’ll look at how we updated tests as we went to ensure our migrations maintained feature parity.
