How to add V8 support to WasmX (Wasm framework for Nginx)

In an exploration of the development process behind Kong's WasmX framework for Nginx, Hisham Muhammad details his journey of integrating support for V8, the JavaScript engine used by Google Chrome, into the system. The narrative unfolds over ten weeks, beginning with Muhammad's onboarding and familiarization with WasmX, and progressing through the technical challenges of adapting V8 to work within the framework alongside existing Wasm virtual machines like WasmTime and Wasmer. The process involved addressing discrepancies in WebAssembly C API implementations, creating a Rust module to facilitate necessary conversions, and tackling the absence of Web Assembly System Interfaces (WASI) in V8. As the project advanced, Muhammad engaged in collaborative efforts to resolve a validation function issue in V8, leading to a successful patch submission. The culmination of this effort was the integration of V8 support within WasmX, verified through thorough testing and continuous integration processes, despite the complexities introduced by differing build environments. This detailed account not only showcases the technical intricacies involved but also highlights the collaborative and iterative nature of software development.
