Val Town Code SearchReturn to Val Town

3It's common to have code and types that are needed on both the frontend and the backend. It's important that you write this code in a particularly defensive way because it's limited by what both environments support:

7For example, you *cannot* use the `Deno` keyword. For imports, you can't use `npm:` specifiers, so we reccomend `https://esm.sh` because it works on the server & client. You *can* use TypeScript because that is transpiled in `/backend/index.ts` for the frontend. Most code that works on the frontend tends to work in Deno, because Deno is designed to support "web-standards", but there are definitely edge cases to look out for.

22
23As of this writing Val Town only supports text files, which is why the favicon is an SVG and not an .ico or any other binary image format. If you need binary file storage, check out [Blob Storage](https://docs.val.town/std/blob/).

187## Val Town Platform Specifics
188- **Redirects:** Use `return new Response(null, { status: 302, headers: { Location: "/place/to/redirect" }})` instead of `Response.redirect` which is broken
189- **Images:** Avoid external images or base64 images. Use emojis, unicode symbols, or icon fonts/libraries instead
190- For AI-generated images, use: `https://maxm-imggenurl.web.val.run/the-description-of-your-image`
191- **Storage:** DO NOT use the Deno KV module for storage
192- **Browser APIs:** DO NOT use the `alert()`, `prompt()`, or `confirm()` methods
