wapm-cli VS packj

To actually compile this we can use a tool called WABT (WebAssembly Binary Toolkit). It's basically a mess that requires CMake and I couldn't get it to run on WSL and I wasn't going to install MinGW. Instead there's a nice tool called WAPM from Wasmer which works like npm for webassembly packages and since it's been compiled down to webassembly we can run it in any environment. In fact we don't even need to add configuration so long as wapm is installed. We can run wax wat2wasm -- wat/mat.wat -o wasm/mat.wasm. wax is like npx for npm. If you're wondering the command we give wax is defined by the wasmer/wabt package: https://wapm.io/wasmer/wabt. Also for some reason you can't prefix local paths with ./ so wax wat2wasm -- ./wat/mat.wat doesn't work which tool me a while to figure out. Anyway this provides a nice simple compile environment if you want to work on raw WAT files.

That's the main reason we should start using WebAssembly for distributing and using packages.

Shamless plug: Wasmer [1] and WAPM [2] could help a lot on this quest!

There's WAPM

If it's buildable for the WebAssembly WASI target, consider also distributing it through WAPM.

I don't know if many people have heard of it, but there's actually a WebAssembly Package Manager. It's similar to crates.io, except you upload WebAssembly binaries written in any language instead of Rust source code!

You can see this paying off with wapm, which lets you download applications that would have normally required compilation for your environment and run them anywhere with a supported runtime, which is imo pretty neat.

One step closer to the day when I can put actix-web creations up on WAPM so "Just type wax my-cool-thing to try it out" can be one of the distribution options.

I've added limited support to run wapm.io directly from the Terminal. Examples of commands that work well are wapm cowsay {Text} and wapm uuid.

Creator of Packj [1] here. How do you envision sandboxing/security policies will be specified? Per-lib policies when you've hundreds of dependencies will become overwhelming. Having built an eBPF-based sandbox [2], I anticipate that accuracy will be another challenge here: too restrictive will block functionality, too permissive defeats the purpose.

Cool project. How do you feel about projects like OpenSSF scorecards or even the checks that socket.dev do today on these packages to help determine risk?

Secondly, what about impersonation where attackers imitate a popular package and its respective metadata?

I built Packj [1] sandboxing for securing “pip/NPM install”. It uses strace for sandboxing and blocks access to sensitive files and limits traffic to known-good IP addresses.

Great work! This provenance check is going to be very valuable for enforcing supply-chain security. We are working on adding support to check for provenance in Packj.

Cool project. Would love to integrate this in Packj [1] as one of the open-source SAST scanners. Will DM you.

Very cool! I've built something similar, but for packages: https://github.com/ossillate-inc/packj Would love to talk.

Working on a marketplace (based on Packj [1]) to allow open-source developers to make money by selling "assured" software artifacts.

I’ve created Packj sandbox [1] for “safe installation” of PyPI/NPM/Rubygems packages

It DOES NOT require a VM/Container; uses strace. It shows you a preview of file system changes that installation will make and can also block arbitrary network communication during installation (uses an allow-list).

Great to see a developer-friendly tool around OSV! Packj [1] uses OSV APIs to report vulnerable PyPI/NPM/Rubygems packages. Disclaimer: I built it.
