I m using miniflare with vitest and

I'm using miniflare with vitest and noticed that it doesn't inject crypto into the env that gets passed to a durable object. I have a work-around where I inject it in my test but it's boilerplate for all tests and I'm wondering if there some way to make it do this via vitest.config.ts?

Hey! 👋 Are you referring to the WebCrypto crypto API, or something else? Would you be able to share the code for your injection workaround to clarify?

Yes, I mean WebCrypto. It doesn't seem to be available to my DOs when running in the miniflare vitest plugin but it is available in wrangler dev and Cloudflare under the env parameter passed to the constructor. My work-around is to modify the env parameter. https://gist.github.com/lmaccherone/67df5ae9977dfd808e8ffd6a6cb62bd6

Hey again! Really sorry for the delayed response here. I've been focused on workerd Windows support for the past couple weeks. I'm still a bit confused what's going on here. With this basic object I see undefined logged. Are you able to share your config or even a minimal reproduction? 
export class Basic {
  constructor(state, env) {
    console.log(typeof env.crypto);
  }

  async fetch() {
    return new Response("body");
  }
}

export default {
  fetch(request, env, ctx) {
    const id = env.BASIC.idFromName("a");
    const stub = env.BASIC.get(id);
    return stub.fetch(request);
  },
};
export class Basic {
  constructor(state, env) {
    console.log(typeof env.crypto);
  }

  async fetch() {
    return new Response("body");
  }
}

export default {
  fetch(request, env, ctx) {
    const id = env.BASIC.idFromName("a");
    const stub = env.BASIC.get(id);
    return stub.fetch(request);
  },
};

Hmmm, I refactored to no longer need crypto and I just now tried to revert and duplicate and can't seem to so maybe something else was going on. Please think nothing more of it. 🙂
