Why?

It would be nice to be able to use libsodium both:

from typescript and be able to both test it in nodejs via ts-jest / ts-node
from browser, packaged with webpack.

What's wrong?

I don't quite know, but both in jest and in ts-node, sodium doesn't get loaded. Observe:

tsconfig.json

{
  "compilerOptions": {
    "target": "es2022",
    "module": "CommonJS",
    // *snip
    }
}

crypto.ts

export async function getSodiumAndCfg(
    sodiumMaybe: typeof sodium0
): Promise<{ sodium: typeof sodium0; cfg: Config }> {
    await sodiumMaybe.ready;
    return { sodium: sodiumMaybe, cfg: config(sodiumMaybe) };
}

export async function blandHash(msg: string): Promise<Url> {
    const { sodium, cfg } = await getSodiumAndCfg(sodium0);
    return toUrl(sodium.crypto_generichash(cfg.hashSize, msg));
}

ts-node

How?

I have no idea what to do about it or how to even debug this. If someone would point me to it, I could try to debug myself.

jedisct1 / libsodium.js

Sodium doesn't load in ts-node or jest tests #298
