react / react-dom 18.3.1 -> 19.2.7; @types/react 18.3.31 -> 19.2.17; @types/react-dom 18.3.7 -> 19.2.3 (latest stable 19.2.x). Only breaking change hitting our code: React 19 removed the no-arg useRef<T>() overload. AppShell's logoutTimer -> useRef<T | undefined>(undefined) — the same transform the official `types-react-codemod preset-19` (useRef-required-initial) applies. No other preset-19 transforms were relevant (already on createRoot; no ReactDOM.render, string refs, propTypes/defaultProps on function components). No Next.js / RSC in this project (it's a Vite SPA served by Fastify), so those React 19 concerns don't apply here. MUI v7, framer-motion 12, TanStack Query 5, react-router-dom 6 and react-quill-new all installed cleanly against React 19 (no peer-dependency conflicts). Gates: tsc 0 | build 0 | vitest 247/247 | eslint 0 errors. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
boha-app-ts
Internal business-management system for a Czech company (attendance, invoicing, leave/trips, projects, vehicles, warehouse, HR) — a TypeScript/Node.js rewrite of the legacy PHP app. User-facing text is Czech by design.

Stack
- Backend: Fastify 5 · Prisma 6 → MySQL · Zod 4 · JWT (HS256) + TOTP 2FA
- Frontend: React 18 · Vite · Material UI v7 (Emotion) · TanStack Query — an
SPA in
src/admin/, served by the same Fastify process (Vite middleware in dev, static files in prod) - Other: Puppeteer (PDF) · nodemailer · node-cron ·
@anthropic-ai/sdk(the admins-only "Odin" assistant)
Prerequisites
- Node.js (LTS) and a MySQL database
- Copy
.env.example→.envand fill in the required vars (DATABASE_URL,JWT_SECRET,TOTP_ENCRYPTION_KEY— generate the keys withopenssl rand -hex 32)
Setup
npm install
npx prisma generate
npx prisma migrate dev # apply migrations to your dev DB
npx prisma db seed # optional: dev-only sample data (NEVER on prod)
Develop
npm run dev:server # API (tsx watch) on http://127.0.0.1:3050
npm run dev:client # Vite dev server (manage separately)
Build & run
npm run build # tsc server → dist/ + vite client → dist-client/
npm start # node dist/server.js
Test
npm test # vitest run — hits a real test DB (.env.test); no Prisma mocks
Quality gates
Before committing, all of these must pass:
npx tsc -b --noEmit # typecheck (NOT `tsc -p tsconfig.json`)
npm run build
npx vitest run
npm run lint # ESLint (incl. react-hooks) — see eslint.config.js
Database migrations
Every schema/data change is a tracked Prisma migration — never prisma db push
or raw SQL on production. Stop the dev server before running prisma migrate dev.
See CLAUDE.md → Database Migrations for the full workflow and the production
deploy/hotfix process.
