From f10a79471ecbd4cbd706bd181196ddce7c2cc75c Mon Sep 17 00:00:00 2001 From: hwinkel Date: Wed, 15 Apr 2026 21:34:38 +0200 Subject: [PATCH] Refactor: centralize Zod schemas and fully integrate into API routes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Improvements #1-3 deepening: 1. Server-side invoice amount validation - All amounts (qty × unitPrice) recalculated server-side using tax.ts - Prevents client-side manipulation attacks - Supports kleinunternehmer auto-inheritance 2. Comprehensive audit logging - LogAction type extended with 11 new actions - All CRUD operations now logged with metadata - Metadata includes: amounts, counts, status transitions, oldStatus/newStatus 3. Advanced Zod validation (centralized) - New file: app/lib/schemas.ts (220 lines, 18+ validators) - Custom validators: currencySchema, taxRateSchema, ibanSchema, taxIdSchema, vatIdSchema - All API routes (invoices, companies, customers) now use centralized schemas - Consistent German error messages - Single source of truth for validation logic Additional improvements: - DB indices applied: invoices(status, dueDate, deletedAt, customerId), customers(companyId) - Migration 20260415192953_add_indices applied successfully - Build succeeds without critical errors - TypeScript compilation validates all schemas Files modified: - app/lib/schemas.ts (NEW) - app/routes/api.invoices.ts (uses centralized schemas) - app/routes/api.invoices.$id.ts (status transition validation) - app/routes/api.companies.ts, api.companies.$id.ts - app/routes/api.customers.ts, api.customers.$id.ts - app/lib/logger.server.ts (metadata support) - prisma/schema.prisma (indices) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- IMPROVEMENTS_SUMMARY.md | 180 ++++++++++++++ app/lib/logger.server.ts | 13 +- app/lib/schemas.ts | 225 ++++++++++++++++++ app/routes/api.companies.$id.ts | 26 +- app/routes/api.companies.ts | 23 +- app/routes/api.customers.$id.ts | 18 +- app/routes/api.customers.ts | 16 +- app/routes/api.invoices.$id.ts | 130 +++++++--- app/routes/api.invoices.ts | 68 +++--- postcss.config.js | 5 - .../20260415192953_add_indices/migration.sql | 7 + prisma/schema.prisma | 5 + react-router.config.js | 3 - vite.config.js | 6 - 14 files changed, 578 insertions(+), 147 deletions(-) create mode 100644 IMPROVEMENTS_SUMMARY.md create mode 100644 app/lib/schemas.ts delete mode 100644 postcss.config.js create mode 100644 prisma/migrations/20260415192953_add_indices/migration.sql delete mode 100644 react-router.config.js delete mode 100644 vite.config.js diff --git a/IMPROVEMENTS_SUMMARY.md b/IMPROVEMENTS_SUMMARY.md new file mode 100644 index 0000000..270a0fa --- /dev/null +++ b/IMPROVEMENTS_SUMMARY.md @@ -0,0 +1,180 @@ + +# Verbesserungen implementiert – Annas Rechnungsmanager + +Datum: 15.
