react-doctor/server-after-nonblocking

`import { after } from 'next/server'` then wrap: `after(() => analytics.track(...))` — response isn't blocked

• Category: Server
• Severity: warn
• Source: oxlint-plugin-react-doctor
• Framework: global
• Enabled when: always

Validation prompt

Use this to decide whether a fired diagnostic is real or a false positive.

Rule only fires inside files with a top-level 'use server' directive or functions carrying their own 'use server'. It flags console.log/info/warn(...) and member calls of the form receiver.method(...) where the receiver is analytics, posthog, mixpanel, segment, amplitude, datadog, or sentry, and the method is one of track, identify, page, capture, captureMessage, captureException, or log. Skip if the return value is awaited or drives downstream control flow.

Fix prompt

Use this once validation confirms the diagnostic is real.

Wrap the deferrable side effect in Next.js's after() so it runs after the response is flushed: import { after } from 'next/server' then after(() => analytics.track(...)). The user-visible response goes out immediately, and the call still executes inside the same request context. See https://nextjs.org/docs/app/api-reference/functions/after

More Server rules from the rules reference:

• react-doctor/server-auth-actions: Add `const session = await auth()` at the top and throw/redirect if unauthorized before any data access
• react-doctor/server-cache-with-object-literal: Pass primitives to React.cache()-wrapped functions — argument identity (not deep equality) is the dedup key, so a fresh `{}` per render bypasses the cache
• react-doctor/server-dedup-props: Pass the source array once and derive the projection on the client — passing both doubles RSC serialization bytes
• react-doctor/server-fetch-without-revalidate: Pass `{ next: { revalidate: <seconds> } }` (or `cache: "no-store"` / `next: { tags: [...] }`) so stale cached data doesn't silently persist
• react-doctor/server-hoist-static-io: Hoist the read to module scope: `const FONT_DATA = await fetch(new URL('./fonts/Inter.ttf', import.meta.url)).then(r => r.arrayBuffer())` runs once at module load
