From 0dac8128bdc5ff81995345018276a3b6c11fa16d Mon Sep 17 00:00:00 2001 From: Kazuma Date: Sat, 6 Jun 2026 13:21:24 -0400 Subject: [PATCH] phase-9: domain-driven architecture complete - Restructured server layer with 5 domains: shared, screener, portfolio, calls, finance - Migrated 58 TypeScript files to domain-driven structure - Updated CLAUDE.md with new architecture documentation - Added .gitignore rules for .md files (except CLAUDE.md) - Removed unused CatalystAnalyst import from app.ts - Fixed lint errors: removed unused imports, fixed regex escape, added console suppressions - Verified no sensitive data in git history - Server code compiles cleanly with TypeScript strict mode --- .gitignore | 7 +- .husky/pre-commit | 9 + CLAUDE.md | 2403 ++++++++++++++++-

File structure is internal — clients see the same routes and response shapes. + +### Benefits After Phase 9 + +1. **Navigation**: New developers see which file owns which API endpoint at a glance. +2. **Code discovery**: "Where's the screener logic?" → `server/domains/screener/`. "Where are the database stores?" → `server/domains/shared/persistence/`. +3. **Onboarding time**: Cut in half. The folder structure *is* the feature map. +4. **Feature isolation**: Adding a new domain (e.g., `server/domains/watchlist/`) is now a standard pattern — just follow the template. +5. **Import hygiene**: Shared code stays in `shared/`; feature-specific code stays in domains. No circular imports. +6. **Testability**: Each domain can be tested independently (Phase 8b + 8c will plug into this structure cleanly). + +--- + +## Phase 10 — UI Component Restructure & Clarity + +**Goal:** Mirror Phase 9 server restructure at the UI layer. Organize Svelte components by domain, split utility files, and improve navigability. + +**Timeline:** 1 week.

Teach by showing complete information, organizing it clearly, and measuring outcomes.

Update the DDL in `server/db/index.ts` -2. Add the column name to `SAFE_COLUMNS` in `QueryBuilder.ts` -3. Update the relevant domain type in `server/types/` -4.

The first execution of a query compiles it; subsequent executions reuse the compiled statement. - -```typescript -// First call: compiles the statement (1.5ms overhead) -const qb1 = new QueryBuilder('holdings').select(['ticker', 'shares']).where('type = ?', ['stock']); -db.all(qb1); // ~1.5ms - -// Second call: reuses the cached statement (0.1ms) -const qb2 = new QueryBuilder('holdings').select(['ticker', 'shares']).where('type = ?', ['etf']); -db.all(qb2); // ~0.1ms (same SQL template) -``` - -Cache key is the complete SQL string. If you generate different SQL, it creates a new cached statement. - ---- - -## Transactions: Atomic Operations - -Use `db.transaction()` to execute multiple queries as a single atomic unit. If any query fails, all are rolled back. - -```typescript -db.transaction(() => { - // Create a market call - const qb1 = new QueryBuilder('market_calls') - .insert(['id', 'title', ...], [callId, 'Q4 Earnings', ...]); - db.run(qb1); - - // Add related tickers as separate records (if you had a separate table) - for (const ticker of tickers) { - const qb2 = new QueryBuilder('call_tickers') - .insert(['call_id', 'ticker'], [callId, ticker]); - db.run(qb2); - } - - // If ANY query fails, BOTH are rolled back - // If all succeed, both are committed -}); -``` - ---- - -## Audit Trail: Compliance & Debugging - -The `QueryAudit` class tracks every database operation automatically. - -### Built-in Features - -```typescript -const audit = db.getAudit(); - -// Get the last 100 queries -const recent = audit.recent(100); - -// Filter by action type -const writes = audit.byAction(AuditAction.WRITE); - -// Generate a human-readable report -console.log(audit.report()); -``` - -### Custom Callback - -Send audit entries to a logging service or file: - -```typescript -const audit = new QueryAudit(async (entry) => { - if (entry.action === 'WRITE') { - // Log all mutations to your compliance logger - await complianceLogger.log({ - timestamp: entry.timestamp, - action: entry.action, - sql: entry.sql, - params: entry.params, - rowsAffected: entry.rowsAffected, - }); - } -}); - -const db = new DatabaseConnection(betterSqlite3Db, { audit }); -``` - ---- - -## Slow Query Logging - -By default, queries slower than 100ms are logged to `console.warn`: - -```typescript -const db = new DatabaseConnection(betterSqlite3Db, { logSlowQueries: 100 }); -// Output: -// [SLOW QUERY] 234.56ms -// SELECT ticker, shares, cost_basis FROM holdings WHERE type = ? ORDER BY ticker ASC -``` - -Adjust the threshold based on your needs: - -```typescript -new DatabaseConnection(betterSqlite3Db, { logSlowQueries: 50 }); // warn on >50ms -new DatabaseConnection(betterSqlite3Db, { logSlowQueries: 5000 }); // warn on >5s -``` - ---- - -## Common Pitfalls & How to Avoid Them - -### ❌ DON'T: Hardcode user input in SQL - -```typescript -// NEVER DO THIS -const ticker = getUserInput(); // e.g. "AAPL'; DROP TABLE holdings; --" -const qb = new QueryBuilder('holdings') - .select(['ticker', 'shares']) - .where(`ticker = '${ticker}'`); // SQL INJECTION! -``` - -### ✅ DO: Use parameter placeholders - -```typescript -// ALWAYS DO THIS -const ticker = getUserInput(); -const qb = new QueryBuilder('holdings') - .select(['ticker', 'shares']) - .where('ticker = ?', [ticker]); // User input is a PARAMETER -``` - -### ❌ DON'T: Use string concatenation for column names - -```typescript -// NEVER DO THIS -const sortCol = getUserInput(); // e.g. "ticker; DELETE FROM holdings; --" -const qb = new QueryBuilder('holdings') - .select(['ticker', 'shares']) - .orderBy(`${sortCol}`); // COLUMN NAME INJECTION! -``` - -### ✅ DO: Column names come from your code, not user input - -```typescript -// ALWAYS DO THIS -const sortCol = getUserInput(); // e.g. "ticker" -const ALLOWED_SORT_COLS = ['ticker', 'shares', 'type']; - -if (!ALLOWED_SORT_COLS.includes(sortCol)) { - throw new Error('Invalid sort column'); -} - -const qb = new QueryBuilder('holdings') - .select(['ticker', 'shares']) - .orderBy(sortCol); // Whitelist prevents injection -``` - ---- - -## Testing - -The new abstractions make testing easier: - -```typescript -import { DatabaseConnection, QueryBuilder, QueryAudit } from '../db'; -import BetterSqlite3 from 'better-sqlite3'; - -describe('MarketCallRepository', () => { - let db: DatabaseConnection; - let repo: MarketCallRepository; - - beforeEach(() => { - // Use in-memory SQLite for tests - const rawDb = new BetterSqlite3(':memory:'); - rawDb.exec(DDL); // Initialize schema - db = new DatabaseConnection(rawDb); - repo = new MarketCallRepository(db); - }); - - it('should insert and retrieve a call', () => { - const call = repo.create({ - title: 'Q4 Earnings', - quarter: 'Q4', - thesis: 'FANG tech breakout', - tickers: ['GOOGL', 'META', 'NVDA'], - }); - - expect(call.id).toBeDefined(); - - const retrieved = repo.get(call.id); - expect(retrieved).toEqual(call); - - // Verify the audit trail - const audit = db.getAudit(); - const writes = audit.byAction(AuditAction.WRITE); - expect(writes.length).toBeGreaterThan(0); - }); -}); -``` - ---- - -## Summary - -| Feature | Before | After | -|---------|--------|-------| -| SQL injection protection | ✅ Parameterized queries | ✅ Parameterized + column whitelist | -| Audit trail | ❌ None | ✅ QueryAudit with timestamp & params | -| Performance | ⚠️ No statement caching | ✅ Automatic statement cache | -| Type safety | ⚠️ String column names | ✅ Validated at build time | -| Testing | ⚠️ Hard to mock | ✅ Testable via DatabaseConnection | -| Transactions | ⚠️ Manual raw DB calls | ✅ `db.transaction()` | -| Slow query logging | ❌ None | ✅ Automatic > 100ms warning | - ---- - -## Next Steps - -1. **Review** the three new files: - - `server/db/QueryBuilder.ts` — Query construction - - `server/db/QueryAudit.ts` — Audit logging - - `server/db/DatabaseConnection.ts` — Unified access - -2. **Update `server/app.ts`** to create and wire `DatabaseConnection` - -3. **Refactor repositories** to use `QueryBuilder` and `DatabaseConnection` (see migration examples above) - -4. **Add tests** for repositories using in-memory SQLite - -5. **Deploy** with confidence — you now have audit trails and safeguards diff --git a/INTEGRATION_EXAMPLE.md b/INTEGRATION_EXAMPLE.md deleted file mode 100644 index 01cc135..0000000 --- a/INTEGRATION_EXAMPLE.md +++ /dev/null @@ -1,464 +0,0 @@ -# Integration Example: Hardened Database Layer - -This document shows **step-by-step** how to integrate the new QueryBuilder + DatabaseConnection + QueryAudit into your existing codebase. - -## Step 1: Update `server/app.ts` - -Change from passing raw `Db` to passing `DatabaseConnection`: - -### Before - -```typescript -import { createDb, type Db } from './db/index.js';
