Can you expand on "use Deno" for installing dependencies? I assume you don't mean to use Deno as the runtime, just for dependency management.

I do mean use Deno as the runtime. Details and examples of how to switch are here: https://crib.social/notice/AwQqG9gm365uat93Nw

How would this have prevented anything?

		In this case it would not have prevented anything, but I never claimed that it would. Using Deno with appropriate sandboxing flags can protect developers against many classes of supply-chain attacks. The reason it doesn't help in this instance is because the attack targets the generated bundle and runs on client devices, whereas other attacks will target developer machines themselves (and possibly also client devices). Those types of attacks can be mitigated by using Deno.
