Looking at the documentation here (https://tinygo.org/docs/guides/webassembly/wasm/#how-it-works), I think you'll need to import and construct a Go instance from the wasm_exec.js file, then pass this to your WebAssembly.Instance:

import "wasm_exec.js"; // or `import { Go } from "wasm_exec.js";`, not sure
import app from "./app.wasm";

const go = new Go();

const instance = new WebAssembly.Instance(app, go.importObject);

...

import "wasm_exec.js"; // or `import { Go } from "wasm_exec.js";`, not sure
import app from "./app.wasm";

const go = new Go();

const instance = new WebAssembly.Instance(app, go.importObject);

...

Hey! 👋 In your entrypoint.mjs module...

import app from "./app.wasm";
const instance = new WebAssembly.Instance(app);
const response = instances.exports.myFunction(...);

import app from "./app.wasm";
const instance = new WebAssembly.Instance(app);
const response = instances.exports.myFunction(...);

Hey! 👋 Unfortunately, this isn't possible at the moment. This was a deliberate choice to ensure that tests are reproducible, as they always start with an empty environment. If you'd like to seed data before running your tests, I'd encourage you to configure VItest setupFiles (https://vitest.dev/config/#setupfiles) with something like...

// vitest.config.ts
export default defineWorkersProject({
  test: {
    setupFiles: ["./test/seed-data.ts"],
    poolOptions: { ... },
  },
});

// vitest.config.ts
export default defineWorkersProject({
  test: {
    setupFiles: ["./test/seed-data.ts"],
    poolOptions: { ... },
  },
});

// test/seed-data.ts
import { env } from "cloudflare:test";

await env.MY_BUCKET.put("key", "value");
// ...

// test/seed-data.ts
import { env } from "cloudflare:test";

await env.MY_BUCKET.put("key", "value");
// ...

R2 multipart uploads do not work in local dev mode with long object keys.

Hey! Wrangler 2 is no longer supported aside from critical security updates. What issues were you seeing with Wrangler 3 and Docker? I remember there were some issues with early versions of Wrangler 3 not working in Docker, but they should be addressed now, assuming you're using images providing glibc 2.31 or higher (i.e. Ubuntu 20.04/22.04, Debian 11/12).
