Cost reduction

[2blo]

• [x] ~view post links as title/desc/before/after....~ - Too ugly, desc can be long.
• [ ] limit nbr of posts per user, easy.
• [x] rate limit query db / requests to vercel - upstash + vercel or theo: middleware,
  • [ ] redirect, instead of just delaying requests.
  • [ ] cannot resume after delay in prod, without refresh
• [ ] limit size / length of db entries

does not redirect usually, when api/path is used

1. trpc middleware interfering?
2. next() does not forward redirect to /blocked?

import { NextFetchEvent, NextRequest, NextResponse } from "next/server";
import { Ratelimit } from "@upstash/ratelimit";
import { Redis } from "@upstash/redis";

const ratelimit = new Ratelimit({
  redis: Redis.fromEnv(),
  limiter: Ratelimit.fixedWindow(4, "10 s"),
});

export default async function middleware(
  request: NextRequest,
  event: NextFetchEvent
) {
  const ip = request.ip ?? "127.0.0.1";

  const requestHeaders = new Headers(request.headers);

  if (request.nextUrl.pathname === "/api/blocked") {
    return NextResponse.next({
      request: {
        // New request headers
        headers: requestHeaders,
      },
    });
  }
  console.log("blocked lol");

  const { success, pending, limit, reset, remaining } = await ratelimit.limit(
    `mw_${ip}`
  );
  event.waitUntil(pending);

  const res = success
    ? NextResponse.next({ request: { headers: requestHeaders } })
    : NextResponse.redirect(new URL("/api/blocked", request.url), request);

  res.headers.set("X-RateLimit-Limit", limit.toString());
  res.headers.set("X-RateLimit-Remaining", remaining.toString());
  res.headers.set("X-RateLimit-Reset", reset.toString());
  return res;
}

export const config = {
  //   matcher: "/api/:path*",
  matcher: "/video",
};

look like all trpc endpoints are the same endpoint with just "virtual endpoints" as the payload:

false ________________
blocked lol http://localhost:3000/api/trpc/content.first?batch=1&input=%7B%220%22%3A%7B%22json%22%3Anull%2C%22meta%22%3A%7B%22values%22%3A%5B%22undefined%22%5D%7D%7D%7D
false ________________

maybe do something in C:\_\git\before-effects\src\server\trpc\context.ts

• we know that the middleware triggers on the trpc endpoints (since it prints), but it fails to redirect

trpc router is most likely the issue, we can get the redirect if we have a "manual" link from /video to api/..., but not with the router

the trpc call is like a fetch, is that functionality different from a http redirect? actually i dont care if redirect is pretty, it should only happen for bots anyway
