per-request-deduplication-with-react-cache

What problem does it solve?

This Skill prevents redundant asynchronous operations, such as database queries or authentication checks, from running multiple times within a single server request, optimizing performance and resource usage.

Core Features & Use Cases

• Server-Side Deduplication: Leverages React.cache() to ensure that expensive async functions are executed only once per request, even if called multiple times.
• Optimized Data Fetching: Ideal for scenarios like fetching user data, performing authentication, or accessing databases where repeated calls within the same request are wasteful.
• Use Case: In a Next.js application, multiple components might independently try to fetch the current user's details. This Skill ensures that the database query for user details runs only once for the entire request, regardless of how many components trigger it.

Quick Start

Use the per-request-deduplication-with-react-cache skill to ensure the getCurrentUser function is only called once per request.
