# Non-JavaScript modules

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://fix-ai-gateway-guardrails-streaming-docs.previews.developers.cloudflare.com/workers/vite-plugin/reference/non-javascript-modules/index.md)|[Agent setup](https://fix-ai-gateway-guardrails-streaming-docs.previews.developers.cloudflare.com/agent-setup/)

In addition to TypeScript and JavaScript, the following module types are automatically configured to be importable in your Worker code.

| Module extension    | Imported type      |
| ------------------- | ------------------ |
| .txt                | string             |
| .html               | string             |
| .sql                | string             |
| .bin                | ArrayBuffer        |
| .wasm, .wasm?module | WebAssembly.Module |

For example, with the following import, `text` will be a string containing the contents of `example.txt`:

```js
import text from "./example.txt";
```

This is also the basis for importing Wasm, as in the following example:

```ts
import wasm from "./example.wasm";

// Instantiate Wasm modules in the module scope
const instance = await WebAssembly.instantiate(wasm);

export default {
	fetch() {
		const result = instance.exports.exported_func();

		return new Response(result);
	},
};
```

Note

Cloudflare Workers does not support `WebAssembly.instantiateStreaming()`.
