data-fetching-rules-for-server-components

data-fetching-rules-for-server-components is a cursor rule for Cursor from paulpham157/paul-s-cursor-rules. It costs 0 tokens per session (123 once invoked), scanned A, original, MIT.

Rules for loading data in Next.js 14 server components. Server components are parts of a Next.js app that fetch data on the server before sending the page to the browser.

In plain words
What is it for?
They guide asynchronous data fetching in `.tsx` files under the Next.js `app` directory, including error handling and periodic revalidation.
Why use it?
They encourage checking failed requests and controlling how long fetched data can be reused.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

data-fetching-rules-for-server-components scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says


description: Rules for data fetching in server components in Next.js 14. globs: /app//*.tsx

  • For data fetching in server components (in .tsx files): tsx async function getData() { const res = await fetch('https://api.example.com/data', { next: { revalidate: 3600 } }) if (!res.ok) throw new Error('Failed to fetch data') return res.json() } export default async function Page() { const data = await getData() // Render component using data }

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
