Backend Node + Express Development Skill

Expert guidance for building production-grade, API-only Node.js + Express backends. This skill ensures every new backend project starts with a clean architecture, consistent patterns, and security-first defaults — whether in JavaScript or TypeScript.

Instructions

Step 1: Confirm Project Basics

Before writing any code, clarify with the user:

1. Language: JavaScript or TypeScript?
2. Database: PostgreSQL, MySQL, MongoDB, or other?
3. ORM/Query builder: Prisma, Knex, Mongoose, raw driver?
4. Auth strategy: JWT or session-based?

If the user doesn't specify, default to: TypeScript + PostgreSQL + Prisma + JWT.
