Safe, Dynamic Middleware with Dapr and WebAssembly

Explore how Dapr implements dynamic extensions with WebAssembly in this informative conference talk. Gain practical insights into the workings of Dapr's event-driven runtime and its rationale for using WebAssembly. Discover how custom HTTP middleware can be implemented without modifying the Dapr binary, leveraging WebAssembly technology. Learn about the http-wasm application binary interface (ABI) and its relationship to other ABIs like proxy-wasm and waPC. Understand the inner workings of the middleware, including the wazero runtime embedded in Dapr for dependency-free WebAssembly execution. Delve into Dapr's long-term extensibility strategy and how WebAssembly fits into the cloud-native architecture without relying on RPC. Leave with a comprehensive understanding of how WebAssembly enables the extension of cloud-native architecture and Dapr's approach to safe, dynamic middleware.
