Tutorials, stack comparisons, tool reviews, and productivity tips — code that ships.
Automate your changelog generation, version bumps, and npm/git tag creation using conventional commits and semantic-release. A practical setup that runs in CI and eliminates manual release work.
Node.js EventEmitter is in every framework and ORM you use, but most teams misuse it in production. Here is how to handle async errors in event listeners, prevent memory leaks with typed events, avoid the maxListeners warning trap, and build a domain event bus that survives real traffic.
ESLint covers the common cases. For everything else there is the TypeScript Compiler API. This post walks through building real custom analysis tools: enforcing domain boundaries between packages, detecting leaked internals, and writing refactoring scripts that understand your codebase.
The dev environment that works on your machine but not on your teammates costs hours of setup time and silently diverges until production breaks. Here is the VS Code Dev Containers setup that gives every engineer the same Node.js version, Postgres port, and system dependencies from a single JSON file.
A no-nonsense benchmark and implementation guide for the three serious password hashing algorithms in Node.js, with production migration strategies, cost tuning, and hash-format portability.
REST and GraphQL both leak a type gap between server and client that costs you a production bug every few sprints. tRPC eliminates that gap entirely. Here is how to build a production tRPC API with authentication, error handling, middleware, and rate limiting, without a code generator or a spec file.
Your orchestrator does not know your container is broken until a user hits it. Docker HEALTHCHECK fills that gap with a three-parameter config and a deliberately boring HTTP endpoint that separates startup, liveness, and readiness into distinct states.
Uploaded images straight from a phone camera are 4-8MB each, and they will crush your bandwidth, your storage costs, and your Lighthouse scores. Here is how to build a production image transformation pipeline with Sharp that resizes, optimizes, caches, and serves images at every breakpoint your layout needs.
Your pager goes off at 2 a.m. Postgres CPU is pegged, queries are timing out, and you have no idea where to look. Here are the eight SQL queries that should be in every production runbook, with the exact thresholds that tell you it is time to act.
Storing API tokens, PII, and secrets in plaintext in your database is a disaster waiting for a SQL injection or a backup leak. Here is how to encrypt sensitive columns at the application layer using Node.js built-in crypto module, with authenticated encryption, proper key derivation, and a zero-downtime key rotation protocol.
