F4 [critical] — the anti-join `DELETE … WHERE NOT EXISTS(child)` was still racy under Postgres READ COMMITTED: a reply INSERT holds FOR KEY SHARE on the parent; the DELETE's start snapshot doesn't see the uncommitted child (NOT EXISTS true), blocks on the reply's lock, and when the reply commits the parent was only LOCKED (not modified) so EvalPlanQual does NOT re-check → the DELETE proceeds and CASCADE destroys the just-committed reply. Replaced with a transaction: SELECT the parent FOR UPDATE (conflicts with the reply's FOR KEY SHARE → serializes the concurrent reply), re-check for a child with a FRESH statement in the same tx (a new RC snapshot sees a just-committed reply), delete only if still childless (return 1) else return 0 (caller resolves). The FOR UPDATE lock is held to end-of-tx so no reply can insert between the re-check and the delete. Signature unchanged, so the service + its mocked unit tests are untouched; docstrings updated. F5 [warning] — the client Dismiss button was gated only on canComment, but the server now gates dismiss on owner-or-space-admin, so a non-owner non-admin saw a button the server 403s. `canShowDismiss` now also requires `isOwnerOrAdmin = currentUser?.user?.id === comment.creatorId || userSpaceRole === "admin"` (the same gate the comment delete-menu already uses); threaded into both call sites. F6 [warning] — added a REAL-DB int-spec (apps/server/test/integration/comment-delete-if-childless.int-spec.ts, + a createComment seeder): (a) childless → returns 1, row gone; (b) committed reply → returns 0, parent+reply survive; (c) CONCURRENCY — a second connection inserts a reply (FOR KEY SHARE) and commits mid-operation while deleteCommentIfChildless blocks on FOR UPDATE → asserts it returns 0 and both rows survive (a blind anti-join would lose the reply here). Ran against live Postgres — 3/3 pass. server tsc clean; comment jest 53 + int-spec 3 (live Postgres) pass. client tsc clean; comment vitest 56 pass.

React + TypeScript + Vite
This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
Currently, two official plugins are available:
- @vitejs/plugin-react uses Babel for Fast Refresh
- @vitejs/plugin-react-swc uses SWC for Fast Refresh
Expanding the ESLint configuration
If you are developing a production application, we recommend updating the configuration to enable type aware lint rules:
- Configure the top-level
parserOptionsproperty like this:
parserOptions: {
ecmaVersion: 'latest',
sourceType: 'module',
project: ['./tsconfig.json', './tsconfig.node.json'],
tsconfigRootDir: __dirname,
},
- Replace
plugin:@typescript-eslint/recommendedtoplugin:@typescript-eslint/recommended-type-checkedorplugin:@typescript-eslint/strict-type-checked - Optionally add
plugin:@typescript-eslint/stylistic-type-checked - Install eslint-plugin-react and add
plugin:react/recommended&plugin:react/jsx-runtimeto theextendslist
