Option 1: Middleware

  1. Import the middleware from https://www.val.town/v/jxnblk/valTownBadgeMiddleware
  2. Wrap your HTML request handler with middleware, and pass import.meta.url to link to your val
import wrapper from "https://esm.town/v/jxnblk/valTownBadgeMiddleware"; async function handler(req: Request): Promise<Response> { const html = ` <h1>Hello, world</h1> `; return new Response(html, { headers: { "Content-Type": "text/html; charset=utf-8", }, }); } export default wrapper(handler, import.meta.url);

Option 2: HTML string generator

  1. Get the HTML string for the badge using https://www.val.town/v/jxnblk/valTownBadge
  2. Add the HTML to your response's HTML string wherever you like
import valTownBadge from "https://esm.town/v/jxnblk/valTownBadge"; export default async function(req: Request): Promise<Response> { const badge = valTownBadge(import.meta.url); const html = ` <h1>Hello, world</h1> ${badge} `; return new Response(html, { headers: { "Content-Type": "text/html; charset=utf-8", }, }); }
