This talk will look at how to stand up a first class API ecosystem using Symfony and Protocol Buffers. Quickly generate client libraries in any programming language for your customers and incorporate performant RPCs and streams. Specifically, we will show how to:

- Define an API using Protobuf and stand up the service using Symfony
- Build client libraries in any language using HTTP and JSON as the transport
- Use Symfony to serve your API over gRPC for increased performance, and take advantage of gRPC streams
