CoWasm: An alternative to Emscripten, based on Zig (demo: Python in the browser)
I am using the Python ecosystem (with full support for dynamic loading of C extension modules) as an initial motivating project. Also, the Python test suite is extremely useful to root out problems. I certainly hope that this can provide a more complete alternative to Emscripten to the community eventually. That said, Emscripten is huge, and the problems involved in creating a more maintainable modular WASM build tool are subtle. For example, when implementing a custom module loader for Python-wasm last week, I discovered several bugs in the memfs and unionfs Javascript libraries (https://github.com/streamich/memfs/pulls?q=is%3Apr+author%3A... and https://github.com/streamich/unionfs/pulls?q=is%3Apr+author%...). I had to learn the code sufficiently to fix all these bugs, submit PR's, etc. Emscripten has its own analogue of memfs, which is optimized specifically for WebAssembly in the browser, where memfs is a more general widely used library (with 10M+ downloads/week).
CoWasm has no support for asyncify. Where I've run into setjmp/longjmp so far, I've been rewriting the code instead. E.g., the dash shell uses setjmp/longjmp, and I'm rewriting that to use return error codes instead (see, e.g., https://github.com/sagemathinc/dash/commit/7117e1f6496728af0...).
> how would I go about porting a simple C->WASM w/ Typescript library project to CoWasm?
That's a great question, which I'm not sure how to quickly answer, so I've created a discussion item here https://github.com/sagemathinc/cowasm/discussions/40

Encryption in PDF Specification and my attempt to do it in pdf-lib
Looks like this whole thing was motivated by the fact that, in order to get the encrypted PDF in a Buffer like they wanted, they had to save to disk and load it back. They could have instead used an in-memory filesystem such as https://github.com/streamich/memfs and just made the existing PDF library that was almost right use that.

I used emscripten to port a command line program to JS/web assembly, now what?
How do I populate the input files? The filesystem API in emscripten talks about MEMFS, is that the same as this? https://github.com/streamich/memfs

I made a Dual N-Back website (My first Open-Source Project), I used to practice this memory game with old websites, software, or some mobile apps, however I decided to create a newer and cleaner interface (Mobile Responsive).
