@rtorcato/api-timeout-express

Express middleware for @rtorcato/api-timeout. Fails a request with 503 if the response isn't sent within a deadline.

import express from 'express'
import { timeoutMiddleware } from '@rtorcato/api-timeout-express'

const app = express()

// Any request not answered within 5s gets a 503 error envelope.
app.use(timeoutMiddleware({ ms: 5000 }))

On timeout the client receives the standard error envelope from @rtorcato/api-errors:

{ "error": "ServiceUnavailableError", "code": "service_unavailable", "message": "Request timed out" }

The middleware sends the 503 and stops. A slow handler that later tries to write will hit Express's "headers already sent" — guard late writes with res.headersSent in long-running handlers.

express is a peer dependency (v4 or v5) — you control the version.
