Bun

Bun is a supported runtime for createNizhalServer().listen() — same Hono app, same adapters.

Proven path

bun apps/credit-ledger/examples/live-e2e.ts
# or: pnpm --filter credit-ledger example:live

The live E2E boots a real TCP server, uses fetch + PartySocket WebSocket, and verifies push/pull convergence.

Notes

• Use Bun’s Node compatibility for postgres driver and Drizzle
• WebSocket upgrade works for /sync/stream with inProcessRealtime
• nizhal migrate runs under Bun when invoked via the CLI entry

No Nizhal-specific Bun APIs — if createNizhalServer works on Node, it works on Bun with the same config.
