From 427195d6dc5e55f45f042487460a7e1da0d8fd5a Mon Sep 17 00:00:00 2001 From: Till JS Date: Fri, 27 Mar 2026 12:40:28 +0100 Subject: [PATCH] feat(todo): add Hono + Bun server for compute-only endpoints New lightweight server replacing NestJS for server-side compute: - RRULE expansion (next occurrence, validation, DoS protection) - Reminders (CRUD with reminder time calculation) - Admin (GDPR user data counts + deletion) - JWT auth middleware + service key auth for admin - Port 3019, ~10 packages vs ~50 for NestJS Co-Authored-By: Claude Opus 4.6 (1M context) --- apps/todo/apps/server/bun.lock |
