Node v19+ Boosts Isomorphic JS with Web Crypto & ES Modules 🌐

In this video, I discuss the extremely exciting `globalThis` feature implemented in Node v19+ which enables relatively simple isomorphic javascript even with the Web Crypto API! This enables us to use the execution environment's implementations without third party code required.

This boils down to exposing `globalThis.crypto.subtle` which is now supported in Node v19+ and major browsers.

I also briefly show what isomorphic unit testing looks like with Jasmine, though I'm planning on dedicating a video to that once import maps are fully supported in jasmine-browser-runner (see https://github.com/jasmine/jasmine-browser-runner/issues/28 )

About ibgib:

This is an ibgib video, about some aspect related to ibgib technologies. In short, ibgib is a web3 metaverse protocol that I've been developing for 20+ years. OK, it's more of my obsession. Instead of assuming a single-source of truth, I've tried to instill humility in its foundations. So even though we are using cryptographic principles, we never assume what our data shows is The Truth or Knowledge. Rather, living logic can best be represented by Beliefs and their evolution over time. Inevitably, this approach leads not only to sovereign, distributed data, but also to some degree of sovereign AIs. This is our approach to metaprogramming.
