During November 2024, this developer expanded the capabilities of the input-output-hk/mithril repository by enabling Node.js integration for the mithril-client-wasm component. They introduced a dedicated build-nodejs target within the Makefile, leveraging wasm-pack to compile the WebAssembly module specifically for Node.js environments. This addition allows the Mithril client to be utilized in server-side and Node-based applications, broadening its deployment options beyond the browser. Their work focused on build systems and WebAssembly, demonstrating proficiency in Makefile scripting and cross-environment module compilation. The contribution addressed a clear integration need, providing a foundation for future server-side usage of the Mithril client.
