PostHog logs for Next.js

What this skill does


# PostHog logs for Next.js

This skill helps you add PostHog log ingestion to Next.js applications.

## Reference files

- `references/nextjs.md` - Next.js logs installation - docs
- `references/start-here.md` - Getting started with logs - docs
- `references/search.md` - Search logs - docs
- `references/best-practices.md` - Logging best practices - docs
- `references/troubleshooting.md` - Logs troubleshooting - docs
- `references/link-session-replay.md` - Link session replay - docs
- `references/debug-logs-mcp.md` - Debug logs with mcp - docs

Consult the documentation for API details and framework-specific patterns.

## Key principles

- **Environment variables**: Always use environment variables for PostHog keys and OpenTelemetry endpoints. Never hardcode them.
- **Minimal changes**: Add log export alongside existing logging. Don't replace or restructure existing logging code.
- **OpenTelemetry**: PostHog logs use the OpenTelemetry protocol. Configure an OTLP exporter pointed at PostHog's ingest endpoint.
- **Structured logging**: Prefer structured log formats with key-value properties over plain text messages.

## Framework guidelines

- For Next.js 15.3+, initialize PostHog in instrumentation-client.ts for the simplest setup

Lightning Web Components with PICKLES methodology and 165-point scoring. Use this skill when the user creates or edits LWC components, builds wire service patterns, or writes Jest tests for LWC. TRIGGER when: user creates/edits LWC components, touches lwc/**/*.js, .html, .css, .js-meta.xml files, or asks about wire service, SLDS, or Jest LWC tests. DO NOT TRIGGER when: Apex classes (use generating-apex), Aura components, or Visualforce.

tanstack-query

Included

Manage server state in React with TanStack Query v5. Set up queries with useQuery, mutations with useMutation, configure QueryClient caching strategies, implement optimistic updates, and handle infinite scroll with useInfiniteQuery. Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.

Included

Process documents with Nutrient DWS. Use when the user wants to generate PDFs from HTML or URLs, convert Office/images/PDFs, assemble or split packets, OCR scans, extract text/tables/key-value pairs, redact PII, watermark, sign, fill forms, optimize PDFs, or produce compliance outputs like PDF/A or PDF/UA. Triggers include convert to PDF, merge these PDFs, OCR this scan, extract tables, redact PII, sign this PDF, make this PDF/A, or linearize for web delivery.
