.well-known/ for Fediverse integration

Hey @Adam Argyle! I'm sure there's a better way than this, but I'd do it by creating a middleware in routes/_middleware.ts like this:

import { FreshContext } from "$fresh/server.ts";

const redirects: [URLPattern, URLPatternInit][] = [
  [
    new URLPattern({ pathname: "/.well-known/host-meta" }),
    { protocol: "https:", hostname: "fed.brid.gy", port: undefined },
  ],
  [
    new URLPattern({ pathname: "/.well-known/webfinger" }),
    { protocol: "https:", hostname: "fed.brid.gy", port: undefined },
  ],
];

export async function handler(req: Request, ctx: FreshContext) {
  // Handle route redirects
  if (ctx.destination === "route" || ctx.destination === "notFound") {
    const matchingRedirect = redirects?.find((entry) => entry[0].test(ctx.url));

    if (matchingRedirect) {
      const destinationPattern = matchingRedirect[1];
      const destinationUrl = buildUrl(
        new URL(ctx.url),
        destinationPattern,
      );

      return Response.redirect(destinationUrl.href, 301);
    }
  }

  // Return other requests as normal
  const resp = await ctx.next();
  return resp;
}

function buildUrl(url: URL, pattern: URLPatternInit) {
  return Object.assign(url, pattern);
}

import { FreshContext } from "$fresh/server.ts";

const redirects: [URLPattern, URLPatternInit][] = [
  [
    new URLPattern({ pathname: "/.well-known/host-meta" }),
    { protocol: "https:", hostname: "fed.brid.gy", port: undefined },
  ],
  [
    new URLPattern({ pathname: "/.well-known/webfinger" }),
    { protocol: "https:", hostname: "fed.brid.gy", port: undefined },
  ],
];

export async function handler(req: Request, ctx: FreshContext) {
  // Handle route redirects
  if (ctx.destination === "route" || ctx.destination === "notFound") {
    const matchingRedirect = redirects?.find((entry) => entry[0].test(ctx.url));

    if (matchingRedirect) {
      const destinationPattern = matchingRedirect[1];
      const destinationUrl = buildUrl(
        new URL(ctx.url),
        destinationPattern,
      );

      return Response.redirect(destinationUrl.href, 301);
    }
  }

  // Return other requests as normal
  const resp = await ctx.next();
  return resp;
}

function buildUrl(url: URL, pattern: URLPatternInit) {
  return Object.assign(url, pattern);
}

It's just a simple little redirect handler that uses web standard URL Patterns to construct the redirect matching rules.
