import { NextResponse } from "next/server";

const aj = arcjet({
  key: process.env.ARCJET_KEY!,
  rules: [
    detectBot({
      mode: "LIVE", // Blocks requests. Use "DRY_RUN" to log only
      allow: [
        "CATEGORY:SEARCH_ENGINE", // Google, Bing, etc
        // Uncomment to allow these other common bot categories:
        // "CATEGORY:MONITOR",  // Uptime monitoring services
        // "CATEGORY:PREVIEW",  // Link previews e.g. Slack, Discord
        // See the full list at https://arcjet.com/bot-list
      ],
    }),
  ],
});

export async function GET(request: Request) {
  const decision = await aj.protect(request);

  if (decision.isDenied() && decision.reason.isBot()) {
    return NextResponse.json({ error: "No bots allowed" }, { status: 403 });
  }

  // Verifies the authenticity of common bots using IP data.
  // Verification isn't always possible, so check the results separately.
  // https://docs.arcjet.com/bot-protection/reference#bot-verification
  if (decision.results.some(isSpoofedBot)) {

function getArcjet() {
  return launchArcjet({ key: process.env.ARCJET_KEY! });
}
const decision = await getArcjet().guard({ ... });
