Emscripten wheels for Pydantic

The blog post discusses the integration of Pydantic with Pyodide and Emscripten, highlighting the transition of Pydantic to a Rust-based core for validation and serialization since version 2. It explains the complexities of building and testing Pyodide wheels, a process that has been facilitated by the acceptance of PEP 783, allowing for the official publication of wheels for the Pyodide CPython distribution. The post delves into the intricacies of the WebAssembly ecosystem, detailing how Python programs can be compiled to WebAssembly using tools like Emscripten, and how the Pyodide environment supports pure Python packages. Additionally, the document provides a detailed guide to building and testing Pyodide wheels, emphasizing the importance of using specific tools and configurations for different Python and Rust versions. The post concludes by highlighting the advancements in Python's WebAssembly support through recent PEPs and encourages experimentation with Pyodide in web environments.
