--- title: "Request-time `generateMetadata` without `htmlLimitedBots` (lint/dynamic-metadata-streaming)" description: "lint/dynamic-metadata-streaming: Since Next 15.2 metadata of dynamic routes is streamed into ``." canonical: https://void-design.vercel.app/rules/lint/dynamic-metadata-streaming lastModified: 2026-09-16 --- # Request-time `generateMetadata` without `htmlLimitedBots` `lint/dynamic-metadata-streaming` · severity **warn** · category Lint · detected by `void lint` and `void audit` ## Why it matters Since Next 15.2 metadata of dynamic routes is streamed into ``. Next's default bot list doesn't include AI crawlers (GPTBot, ClaudeBot, PerplexityBot) or plain Googlebot, so they receive a `` without title/canonical. ## How to fix it Make the route static (`generateStaticParams`, `'use cache'`), or set `htmlLimitedBots` in next.config to Next's default list plus AI crawlers. ## Example ```ts const nextConfig: NextConfig = { htmlLimitedBots: /Googlebot|GPTBot|OAI-SearchBot|ChatGPT-User|ClaudeBot|Claude-User|PerplexityBot|Bingbot|facebookexternalhit|Twitterbot|LinkedInBot|Slackbot/i, } ``` ## References - https://nextjs.org/docs/app/api-reference/config/next-config-js/htmlLimitedBots - https://nextjs.org/docs/app/api-reference/functions/generate-metadata#streaming-metadata ## More lint rules `void lint` reports 67 rules in this category.
