+# Cloudflare Workers + Hono + Angular SaaS
+
+Full-stack SaaS on Cloudflare Workers with Hono API, Angular frontend, and enterprise integrations.
+
+## Stack
+CF Workers+Hono v4.12+ | Angular 21+Ionic 8+PrimeNG 21 | D1/Neon | Drizzle v1 | Zod | Clerk Core 3 | Stripe | Inngest v4 | Resend | Bun 1.3 | Playwright v1.59+ | Vitest | ESLint+Prettier | PostHog | Sentry
+
+## TypeScript
+- Strict mode, never `any` (use `unknown`), prefer `interface` over `type`
+- `readonly` when not reassigned, `undefined` over `null`
+- Zod as source of truth for validation
+- ESLint flat config (`eslint.config.ts`) + typescript-eslint + Prettier
+
+## Hono API
+- Inline handlers for RPC type inference (never separate controller files)
+- Method chaining: `app.use().get().post()` preserves types
+- `hc<AppType>(BASE_URL)` for typed client
+- `@hono/zod-validator` on ALL request bodies
+- `app.onError()` + `app.notFound()` centralized
+- Split large apps: `app.route('/path', subApp)`
+- Error envelope: `{ error: string, code?: string, details?: unknown }`
+- `createFactory<{ Bindings: Env }>()` for reusable middleware chains
+- `GET /health` returns `{ status, version, timestamp }`
+
+## Angular
+- Standalone only (no NgModules), Angular 21 zoneless by default
+- Signals stable: `signal()`, `computed()`, `effect()`, `linkedSignal()`, `resource()`
+- `HttpResource` for data fetching
+- Control flow: `@if`/`@for`/`@switch`/`@defer` (not `*ngIf`/`*ngFor`)
+- kebab-case files, one component per file, `providedIn: 'root'`
+- PrimeNG for UI components
+
+## Drizzle v1
+- `sqliteTable` for D1, plural snake_case tables
+- `$inferSelect`/`$inferInsert` for types
+- `createInsertSchema`/`createSelectSchema` from `drizzle-orm/zod`
+- Batch API (not `BEGIN` — D1 doesn't support transactions)
+- Prepared statements for repeated queries
+
+## CF Workers
+- CPU limit: 10ms free / 30s paid
+- `ctx.waitUntil()` for async post-response work
+- `ctx.passThroughOnException()` for graceful degradation
+- Bindings typed via `Env` interface
+- D1 global read replication for latency reduction
+
+## Inngest v4 (Background Jobs)
+- `eventType('name', { schema: z.object({...}) })` per-event (v4 breaking)
+- `inngest/cloudflare` adapter + `inngest.setEnvVars(c.env)` for Workers
+- Step functions: `step.run()`, `step.sleep()`, `step.waitForEvent()`, `step.sendEvent()`
+- `step.ai.infer()` offloads inference (zero compute during wait)
+- Each step idempotent, retried independently
+
+## Testing (TDD)
+- Failing test FIRST, then implement
+- Playwright for E2E: 6 breakpoints (375, 390, 768, 1024, 1280, 1920)
+- Vitest for unit tests
+- No sleeps — use `waitFor`/`toBeVisible()`
+- Selectors: `data-testid` > role > text
+- axe-core 0 violations
+
+## Security (OWASP Top 10:2025)
+- Must: HSTS, CSP (nonce-based strict), X-Content-Type-Options, X-Frame-Options
+- Must: Referrer-Policy, Permissions-Policy, COOP, COEP, CORP
+- Remove: X-XSS-Protection, Expect-CT, Server, X-Powered-By
+- Turnstile on all forms, Zod validation on all inputs
+
+## Auth (Clerk)
+- JWT verified per-request (no session store)
+- Webhook sync: Clerk → D1 for user data
+- RBAC: Clerk org roles + D1 app-level roles
+
+## Quality
+- Lighthouse: a11y ≥95, perf ≥75
+- WCAG 2.2 AA compliance
+- LCP ≤2.5s, CLS ≤0.1, INP ≤200ms
+- JS ≤200KB gz, CSS ≤50KB gz
+
+## Starter
+```typescript
+import { Hono } from 'hono';
+import { secureHeaders } from 'hono/secure-headers';
+import { cors } from 'hono/cors';
+
+interface Env {
+  DB: D1Database;
+  KV: KVNamespace;
+  AI: Ai;
+  TURNSTILE_SECRET: string;
+}
+
+const app = new Hono<{ Bindings: Env }>();
+app.use('*', secureHeaders());
+app.use('/api/*', cors({ origin: ['https://yourdomain.com'] }));
+app.get('/health', (c) => c.json({ status: 'ok', timestamp: new Date().toISOString() }));
+export default app;
+```
