autobox VS LavaMoat

Once I'm done with (2) though I think I'll tackle (3).

`autobox` is fun but I think it may be impractical without more language level support and no matter what I'd end up having to implement it in the compiler at some point, which means it would be unusable without nightly or a fork.

I'm going to try to wrap up an autobox POC that handles branching and loops, publish it, and see if someone who does more compilery things is willing to pick it up. As for (2) and (3) I believe I can build practical implementations for both.

Just yesterday I watched a talk [0] at WarsawJS about LavaMoat [1], a set of tools to protect against malicious behaviour from npm dependencies. Guess it’s time to look into it deeper.

You are basically talking about Lavamoat. It provides tooling and policies for SES, which aims to make it into standards.

Enter: lavamoat. https://github.com/LavaMoat/LavaMoat

You should check out Lavamoat: https://github.com/LavaMoat/LavaMoat

It attempts to do what you're essentially describing. It was built by the MetaMask team, where supply chain attacks are an obviously huge risk.

I've spent some time trying to get it working in an app, but haven't been able to get it all the way working. It's still pretty beta and not well documented.

And it is happening right now. Github is opening the GitHub Advisory Database to community submissions. Awesome community NodeSecure builds cool things like scanner and js-x-ray. There are also lockfile-lint, LavaMoat, Jfrog-npm-tools (and I am sure there is more).

There is a proposal to add OCAPs on a language level in TC39[0]. There is already a drop-in implementation which already works in both Nodejs and browsers[1].

As a developer who wants to sandbox your own (recursive) dependencies, this is made accessible today in Lavamoat[2]. Basically a package or app can provide a policy manifest specifying which capabilities (e.g. network or filesystem access) should be granted for each dependency. Also comes with a tool that will auto-generate a starting point from your existing dependency tree.

IMO this is the future. Currently it does come with a performance penalty but hopefully this idea will catch on and make it into runtime implementations.

Lavamoat is still marked as "preprod" on npm but talking to the author it's a matter of days or weeks until the first stable release.
