1. Use the latest version of Node.js: Always use the latest stable version. This will provide you with performance improvements, security patches, and access to the latest features that can streamline coding.
1. Avoid Synchronous code: Synchronous code can block the event loop and prevent other operations from being executed. Try to use asynchronous code whenever possible to increase the performance.
1. Use Clustering: Node.js is a single threaded application, which means it can utilise only one CPU core at a time. With clustering, we can create worker processes that share the same server port, enabling load balancing over several processes.
1. Error handling: Proper error handling can prevent applications from crashing and causing downtime.
1. Correct use of data types: Different data types have different performance and memory impacts. Use the correct data type to help improve your application’s performance.
1. Use Gzip compression: Gzip compression significantly reduces the size of data sent from your server. This means that your website will load faster.
1. Caching: Caching data can significantly reduce server load and improve performance by minimizing database queries and rendering time.
1. Profiling and monitoring: Monitor your application performance proactively so you can identify and resolve issues before they affect the users.
1. Use Promises: Promises can help you manage asynchronous operations more effectively, leading to a more effective use of system resources.
1. Keep code small and light: Frugal code is easier to load, easier to read, easier to test and easier to manage.
1. Optimize Database Operations: Optimize any queries and implement indexing where required to make your database operations faster.
1. Leverage Google’s V8 Profiling: Node.js operates on Google’s V8. Named for standing up eight engines, V8 has both a profiler and a heap profiler that we can use.
