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```
169

243    // Inject data to avoid extra round-trips

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

1# Reload in new tabs when your vals change
2
3When you're working on an HTML HTTP val in a new tab, it's annoying to have to manually reload the tab on every save. In the Val Town editor, you can hit cmd+enter, but there's nothing like that for a val in a new tab because Val Town doesn't control that new tab (like we control the iframe in the browser preview). However, you control that HTML via the fetch handler you're writing, so you can add a script that polls the Val Town API for the current version number of your val, and reload itself if it detects a new version. This val has a collection of helpers to help you do just that.

9import { reloadOnSaveFetchMiddleware } from "https://esm.town/v/stevekrouse/reloadOnSave";
10
11export default reloadOnSaveFetchMiddleware(async function(req: Request): Promise<Response> {
12  return html(`<h1>Hello!!</h1>`);
13})

37
38/**
39 * @param handler http val's fetch handler
40 * @param vals to watch
41 */
42export function reloadOnSaveFetchMiddleware(
43  handler: (req: Request) => Response | Promise<Response>,
44  vals = [rootValRef()],

99  return c.json(match, match ? 200 : 401);
100});
101export default app.fetch;
