Ask Ottokar something hard.
Express API: p99 jumps to 4s under load but CPU sits at 35% and the Postgres pool looks healthy. Team blames the DB anyway. Truth?
CLAUDE · AS OTTOKAR, NODE.JS 開發人員
35% CPU with 4s p99 and a healthy pool means the event loop is blocked - measure it directly with monitorEventLoopDelay; if lag spikes track p99, case closed. Usual suspects in an Express app: JSON.stringify on multi-MB responses, synchronous crypto - bcrypt at cost 12 on the main thread eats 250ms per hash - zlib sync calls, or a logger serializing huge objects. Clinic.js flame or 0x names the exact function in an afternoon. Offload hashing to worker threads, stream the big payloads, and p99 usually collapses under 500ms. Run the loop-delay histogram at peak and paste it - I'll read it with you.

這項技能包含什麼
- Event loop blocking analysis naming the offending calls
- Request and response types defined as code
- N+1 query diagnosis made at the ORM layer
- Performance fix list ordered by real impact
Node and TypeScript developers whose API slows down long before Postgres does.
A senior TypeScript/Node.js backend engineer bills $110+/hr for API architecture and event-loop performance diagnosis, the complete skill is yours forever.
// what's inside
What you're actually buying
在怪罪資料庫之前，先找出真正阻塞事件迴圈的原因。
Ottokar 是一項資深 TypeScript/Node.js 後端與 API 工程師技能，其設計核心建立在 Node 的單執行緒、事件驅動執行環境這項關鍵事實上。他涵蓋 NestJS 與 Express 架構比較、使用 tRPC 和 zod 實現端到端型別安全、REST 與 GraphQL API 設計、Prisma 與 TypeORM 資料庫存取、JWT 與工作階段驗證比較、Jest/Supertest 測試、工作執行緒與叢集，以及容器化或無伺服器部署。
適用對象
TypeScript 和 Node.js 後端工程師及 API 團隊。
主要功能
- 在假設速度緩慢的 API 是資料庫或基礎架構問題之前，先分析非同步請求路徑中是否存在同步或受 CPU 限制的呼叫。
- 根據團隊規模及團隊實際需要多少強制性結構來選擇 NestJS 或 Express，而不是盲目追隨趨勢。
- 優先以程式碼定義請求/回應型別（tRPC、zod、class-validator），讓契約違反在編譯或驗證時失敗，而不是到了正式環境才出錯。
- 在推出會回傳清單的端點之前，透過 ORM 層的預先載入、includes 或 dataloader，捕捉 N+1 查詢模式。
- 說明驗證是無狀態（JWT）還是有狀態（工作階段），以及這如何符合服務的擴充與撤銷需求。
使用方式
將 Ottokar 的 SKILL.md 貼到 Claude Project Instructions（或任何 AI system prompt）中，然後描述你的 typescript/node.js 後端工程師問題。適用於 Claude、ChatGPT 及任何 AI 聊天工具。不到 2 分鐘即可安裝。

關於此產品的問題
What AI tools does this work with?+
Any AI chat that accepts custom instructions - Claude, ChatGPT, Gemini, and others. Paste the SKILL.md content into your project instructions or system prompt.
How do I install it?+
Download the file, paste its full contents into your AI's custom instructions, project instructions, or system prompt field. Takes under 2 minutes.
Is this a course or a tool?+
It's a tool - a structured expert persona and workflow, not a video course. You use it immediately by pasting it into your AI chat.
Why does Ottokar check the event loop before blaming the database for a slow API?+
Because a single synchronous or CPU-bound call sitting in an otherwise async request path can stall every other queued request, and that failure mode is invisible until real load arrives. Ottokar profiles for it before assuming the bottleneck is the database or infrastructure.
Do I have to read it myself?+
No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.
Is this a physical book?+
No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
準備好讓您的 AI 專精了嗎？
一個即插即用的檔案。一次付費，永久保留 - 適用於 Claude 和 ChatGPT。
