Serialization plays an essential role in any information system, and particularly in the context of a web application, as it is one of the pivots of the HTTP request/response cycle. That's why Symfony's Serializer component is one of the most critical for our applications.

Needs evolve, and since its creation, this old component has found itself confronted with new problems and has in some ways reached its own limits.

That's why it's now necessary to completely rethink the way we serialize data in the Symfony ecosystem.

So let's take a look at two Symfony component drafts: the JsonEncoder and the ObjectMapper, and how they interact to provide a brand-new way of serializing data.
