TypeScript Error Handling in Production: Result Types, Error Boundaries, and Graceful Degradation
try-catch gets you started but it fails at scale. This guide covers Result types, discriminated unions, React error boundaries, API error design, and observability integration for TypeScript applications that need to stay alive under real conditions.
Edge-First Architecture with Cloudflare: D1, R2, KV, and Queues Working Together in Production
A unified architecture guide for building full-stack applications on Cloudflare's edge platform. Covers when to use each primitive, how they compose in a real application, data flow patterns, consistency tradeoffs, and production gotchas with a concrete TypeScript example.
End-to-End Type Safety in Full-Stack TypeScript: From Database to UI Without Runtime Surprises
TypeScript doesn't prevent runtime type errors by itself. Learn how to close the gaps across the full stack using Drizzle, Hono RPC, Zod, and shared schemas so your types survive all the way from the database to your React components.
React Performance Patterns: Memoization, Virtualization, and Bundle Splitting for Production Apps
A practical guide to React performance optimization that actually matters in production. Covers measurement with React DevTools and web vitals, memoization tradeoffs, list virtualization with TanStack Virtual, code splitting with React.lazy, and bundle analysis.
Cron Jobs in Serverless Environments: Cloudflare Cron Triggers, AWS EventBridge, and Inngest Compared
Serverless platforms don't have a persistent process to run crontab. This guide compares Cloudflare Cron Triggers, AWS EventBridge + Lambda, and Inngest on scheduling semantics, failure handling, observability, and cost, with TypeScript implementations for each.
Middleware Patterns in Modern Web Frameworks: Hono, Next.js, and Express Compared
A deep comparison of middleware architecture across Express, Hono, and Next.js for TypeScript engineers. Covers composition models, type safety, common patterns like auth and rate limiting, production performance, and a framework decision guide.
OAuth 2.0 and OpenID Connect in Practice: Flows, PKCE, and Token Management in TypeScript
OAuth 2.0 is a delegation protocol, not an authentication protocol. This covers why both exist, the Authorization Code Flow with PKCE for SPAs and server apps, TypeScript implementation of token exchange and ID token validation, refresh token rotation, common security mistakes including implicit flow and localStorage, session management post-login, and a concrete guide to hosted providers vs rolling your own.
Choosing a Database for Your SaaS Startup: Postgres, PlanetScale, Neon, and Turso Compared
A practical comparison of database options for modern SaaS startups. Covers Postgres (self-managed and managed), PlanetScale, Neon, Turso, and Supabase across connection models, serverless compatibility, scaling characteristics, pricing at startup scale, and developer experience, with TypeScript examples using Drizzle ORM.
Drizzle vs Prisma vs TypeORM: Choosing a TypeScript ORM for Production
A practical comparison of Drizzle, Prisma, and TypeORM across migration story, query builder ergonomics, type safety, raw SQL escape hatches, serverless connection pooling, and performance. Real TypeScript code showing the same operations in all three, with a tradeoffs table and guidance for startup teams.
TypeScript Monorepo Architecture: Turborepo, Nx, and pnpm Workspaces for Production Teams
How to structure a TypeScript monorepo for a growing team. Compares Turborepo, Nx, and plain pnpm workspaces across build performance, dependency management, CI integration, and developer experience.
Database Connection Pooling in Serverless Environments: PgBouncer, Neon, and Hyperdrive Compared
Serverless functions create a new database connection per invocation, quickly exhausting PostgreSQL's connection limit. This guide explains the connection pooling problem in serverless, covers the three main solutions (self-hosted PgBouncer, Neon's built-in pooler, and Cloudflare Hyperdrive), compares their architectures and tradeoffs, and provides a decision framework.
Database Migrations in Production: Zero-Downtime Schema Changes for Growing Startups
ALTER TABLE locks your table and takes your site down. This guide covers the expand-contract pattern, online schema migration tools (gh-ost, pgroll, pt-online-schema-change), TypeScript migration tooling (Drizzle, Prisma, Kysely), backfill strategies, rollback plans, and a decision framework for when you actually need zero-downtime DDL.
