Add Error Tracking (Sentry/LogRocket) 🔍

Recommendation: Integrate error tracking for production:

// packages/logger/src/sentry.ts
import * as Sentry from "@sentry/nextjs";

Sentry.init({
  dsn: process.env.SENTRY_DSN,
  environment: process.env.NODE_ENV,
  tracesSampleRate: 1.0,
});

Add Request ID Middleware 🆔

Create: packages/trpc/src/middleware/request-id.ts

import { v4 as uuidv4 } from "uuid";

export function addRequestId() {
  return async ({ ctx, next }: { ctx: any; next: any }) => {
    const requestId = uuidv4();
    return next({
      ctx: {
        ...ctx,
        requestId,
      },
    });
  };
}

Add Database Query Timeout ⏱️

Recommendation: Add query timeouts to prevent hanging queries:

// packages/drizzle/src/index.ts
export const db = drizzle(sql, {
  maxRetries: 3,
  retryDelay: 1000,
});

No Pre-commit Hooks

Issue: No Husky or lint-staged configuration to enforce code quality before commits.

Recommendation:

• Install Husky and lint-staged
• Configure pre-commit hooks for:
  • Linting
  • Type checking
  • Formatting
  • Test running (optional)

Action: Set up Husky with lint-staged configuration.
