Explore the practical implementation of WebAssembly in production through a conference talk that delves into building a compiler for the Roc programming language as a web-based tool. Learn about WebAssembly basics, the challenges of porting to Wasm, and strategies for optimizing download size. Discover how to overcome Wasm limitations, utilize Web APIs, handle input/output, and manage JavaScript/Wasm interoperability. Gain insights into evaluating user-generated code and the overall architecture of a complex WebAssembly project deployed for real users.
