Deep dives into Node.js runtime safety, architecture enforcement, and production performance.
AI tools like Cursor and Copilot generate code fast but ignore your architecture rules. Learn how AI-generated code introduces layer violations and how to enforce boundaries automatically.
Step-by-step tutorial to set up automatic PR quality gates that block dangerous code patterns. Works with GitHub Actions and any Node.js project.
Your API is 10x slower than it should be. N+1 queries hide in every ORM. Learn how to detect and fix them in Prisma, TypeORM, and Sequelize with real code examples.
Learn practical node js performance optimization techniques to fix slow APIs, event loop blocking, N+1 queries, unbounded fetches, and database bottlenecks before they reach production.
Learn the most common reasons for poor node js performance, from event loop blocking to N+1 queries and unbounded fetches, and how to fix slow APIs before they reach production.
Understand the Node.js event loop, how blocking code affects performance, and how to prevent event loop lag in real backend applications.
Learn how to detect and fix event loop blocking in Node.js with real examples, including sync I/O, CPU-heavy loops, and JSON bottlenecks.
These 12 patterns silently kill Node.js backends in production. Most code reviewers miss them. Here's what they are, why they're dangerous, and how to catch them before merge.
Technical debt explained for developers. What it is, the 5 types, real examples, how to measure it, and how to fix it before it kills your velocity.
A practical guide to measuring, tracking, and reducing technical debt in Node.js and TypeScript projects. Includes scoring formulas, automation, and real examples.
An honest comparison between SonarQube and Technical Debt Radar for Node.js teams. What each tool catches, misses, and costs.
We ran Technical Debt Radar on nestjs-realworld-example-app and found 14 real bugs that every NestJS developer should know about.
