What problem does it solve?

Node.js applications often struggle with efficient and reliable relational database access. This skill provides a structured set of design patterns covering connection pooling, transaction management, safe dynamic SQL, parameterized queries, and migration strategies to improve robustness and performance.

Core Features & Use Cases

• Connection pooling configuration and health checks to reduce latency and resource usage.
• Transaction encapsulation wrappers to ensure ACID guarantees across multi-step operations.
• Parameterized queries with safe dynamic SQL construction to prevent SQL injection.
• Migration strategies using Knex.js, Prisma, or handwritten SQL to manage schema changes.
• Patterns for read/write splitting and basic replication awareness to scale reads.

Quick Start

Configure a pool, implement a transaction wrapper, and validate a few representative queries against your test database.
