Make server-side posthog-node capture serverless-safe#228
Merged
Conversation
The javascript_node block told the agent not to set flush config in "long-running servers", which caught web frameworks whose per-request handlers are actually short-lived on serverless/edge — so generated capture code returned before the async send ran and dropped events. Reframe per-request handlers as short-lived and require an awaited flush()/shutdown(), and add the same rule to the nextjs, astro-ssr, astro-hybrid, and sveltekit blocks.

The singleton examples captured and returned without awaiting the send; that works on a long-lived dev server but drops events on serverless/edge where the function freezes on return. Add await posthog.flush() before each handler returns, and give nuxt-4 the flushAt/flushInterval config the other examples already have. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Reframes the commandments so per-request handlers in web frameworks (Next.js/Nuxt/SvelteKit/Astro, serverless, edge) are treated as short-lived and must await
flush()/shutdown(), and fixes the server example handlers to await the send before returning — the drift that let the wizard generate capture code that silently drops events on serverless.
