What are the optimization techniques used in Node.js?

Question

Accepted Answer

Node.js optimization techniques enhance performance, reduce latency, and improve resource management for backend applications.

Use asynchronous programming to handle multiple requests without blocking the event loop.
Implement caching strategies (e.g., Redis) to store frequently accessed data and reduce database load.
Optimize database queries by using indexes and avoiding N+1 query problems.
Utilize clustering to take advantage of multi-core systems, allowing Node.js to handle more requests concurrently.
Minimize the use of synchronous functions, which can block the event loop and degrade performance.
Leverage tools like PM2 for process management and monitoring to ensure optimal resource usage.
