    One place that I’ve found some real, open source unit tests to look at for an example is in the emsdk for emscripten: https://emscripten.org. Source: 7 months ago
  • Playing with low-level memory in WebAssembly
    I am playing around with Emscipten which wraps around clang to compile C/C++ code in WASM binary and provide some glue-code API to embed WASM binary into JavaScript. Look into MDN Docs and Emscripten SDK to get started. - Source: dev.to / 10 months ago
  • Is there any alternative other than JavaScript to deal with web frontend?
    Elm is a different approach that compiles into JavaScript. In the extreme case, you have Emscripten which will compile many language into JavaScript but will feel really clumsy compared to using JavaScript in a lot of cases. Source: about 1 year ago
  • SQLite builds for WASI since 3.41.0

This enables a new set of possibilities for Wasm and SQLite. For example, now you can run a full WordPress application in the browser [1][2] / server [3] using the same Wasm module. Note that for the browser these projects use Emscripten [4],... - Source: Hacker News / about 1 year ago
