Implementing a WASI Host for Visual Studio Code

Explore the implementation of a WASI host for Visual Studio Code in this 51-minute conference talk by Dirk Bäumer from Microsoft. Discover how the VS Code team achieved their goal of supporting full edit/compile/debug development cycles for languages like Python and C/C++ in VS Code for the Web. Learn about the process of developing a WASI host on top of VS Code's extension host API, enabling the execution of Python code by compiling a Python interpreter to WASM. Examine the various design choices considered for the WASI host and gain insights into the transition from WASI snapshot preview1 to the new component model. Understand how VS Code extension authors can leverage this implementation to run their own WebAssembly code using VS Code's WASI implementation, enhancing the capabilities of web-based development environments.
