Keeping My Website Chatbot Under a 9-Second Serverless Timeout

说明与用途

网站聊天机器人通过使用快速 AI 模型、4 秒 AbortController 和关键词回退，消除了超时问题。

问题

Website chatbots timed out on serverless platforms, causing 504 errors and lost customers.

结果

Chatbot latency dropped below the serverless timeout, eliminating 504 errors and improving user experience.

工作流

• Receive HTTP POST from chat widget
• Package prompt and send to external AI API
• Wait for completion with a 4‑second AbortController timeout
• If fetch succeeds, parse JSON and return reply
• If fetch aborts or errors, parse user input for keywords
• Return a deterministic fallback response

证据

If the AI provider experiences high latency, your function crosses that 10-second threshold.

I use the native AbortController in Node.js to enforce a strict fetch timeout.

I implemented a deterministic keyword matcher as a fallback layer.
