1655. **fetchTranspiledJavaScript** - Fetch and transpile TypeScript to JavaScript:
166```ts
167const jsCode = await fetchTranspiledJavaScript("https://esm.town/v/username/project/path/to/file.ts");
168```

244    const initialData = await fetchInitialData();
245    const dataScript = `<script>
246      window.__INITIAL_DATA__ = ${JSON.stringify(initialData)};

3015. **API Design:**
302   - `fetch` handler is the entry point for HTTP vals
303   - Run the Hono app with `export default app.fetch // This is the entry point for HTTP vals`
304   - Properly handle CORS if needed for external access

26## Implementation Details
27
28- The proxy uses standard fetch API to forward requests
29- URL transformation handles both absolute and relative URLs
30- The widget is injected before the closing `</body>` tag when possible
