Technical Knowledge Hub
Insights, tutorials, and experiences from my journey in software development. Sharing knowledge one post at a time.
cluster module in node js
The Cluster module in Node.js allows developers to create child processes, known as workers, that share the same server port. Each worker can handle incoming requests independently, taking advantage of multiple CPU cores. This distribution of tasks across workers ensures that the application can handle a larger number of concurrent requests, enhancing its performance and responsiveness.
Next.Js authentication using Lucia
Handling authentication is a complicated yet crucial task. Recognizing the importance of a robust and secure authentication system, Lucia be an excellent solution for your next project. As a lightweight auth library specifically designed for TypeScript, Lucia abstracts the intricacies of managing users and sessions, making the developer’s job significantly easier.
Caching in React
Caching is a technique used to store data in a temporary memory area for faster access. In React applications, caching can significantly improve performance by reducing the time required to recompute values that do not change frequently. Two essential hooks for implementing caching in React are useMemo and useCallback.
