In this session, we'll dive into the fascinating world of Envoy Proxy's WASM extension capability. You see, GraphQL is a widely embraced method for bringing together data from lots of different microservices to serve up to your applications. Typically, this happens after the request passes through API gateways, such as Envoy.

But here's where things get intriguing: thanks to Envoy's WASM extension filter, we can actually embed GraphQL right within the Envoy-based gateway itself. What does this mean for you? It means you can simplify your setup by eliminating the need for an extra layer of infrastructure maintenance. In essence, it's like streamlining your system for greater efficiency. In this talk we shall delve deep into envoy's WASM extension nuances with practical implementation using GraphQl Federation setup.
