Val Town API URL

When Val Town code is run on Val Town servers we use a local URL so we can save time by skipping a roundtrip to the public internet. However, if you want to run your vals that use our API, ie std library vals, locally, you'll want to use our public API's URL, https://api.val.town. We recommend importing and using std/API_URL whenever you use our API so that you are always using the most efficient route.

Example Usage

Create val
import { API_URL } from "https://esm.town/v/std/API_URL";

const response = await fetch(`${API_URL}/v1/me`, {
    headers: {
      Authorization: `Bearer ${Deno.env.get("valtown")}`,
      Accept: "application/json",
    },
});
const data = await response.json();
console.log(data)

function envOrUndefined(key: string): string | undefined {
// try/catch prevents crashes if the script doesn't have env access
try {
return Deno.env.get("VALTOWN_API_URL");
} catch {}
}
export function getApiUrl(): string {
return envOrUndefined("VALTOWN_API_URL") ?? "https://api.val.town";
}
export const API_URL = getApiUrl();
