- Avoid Synchronous Code:
As discussed above, Node.js is based on asynchronous and non-blocking APIs. It uses a single threaded model which means that when your code runs longer operations then the thread will be blocked until the operation gets finished and hence, this takes time for next operation to take place. So, if you want to enhance the performance of website or application, never use synchronous code with Node. Always use only asynchronous APIs in your code especially in the performance critical sections.
- Running Multiple Functions in Parallel:
Sometimes in your Node.js website development process, you may require calling the multiple APIs for fetching various data. In this case take care to make your API calls execute in a parallel fashion instead of one after the other. This will cut down the call execution time and moreover improve the speed of your website or application drastically.
- Implement the Client Side Rendering Technique:
Today there are client side frameworks which instead of rendering on the server will just expose APIs sending JSON to the client. On the client side, a framework is used to display this JSON on UI. Hence, this saves bandwidth and will improve the speed of the website or applications based on Node.js.
- Optimize your Code to keep it Small & Light:
Hence, by following the above practices in Node.js web development process, developers can ensure to drastically improve the performance of their websites or applications.
