In recent times, every businesses even it is small or large must have a website and android application for enhancing their business into top-notch level. They are in continuous need of applications that can execute on all platform smoothly and successfully and they have nodejs - the ideal solution for the server-side development.

NodeJS has been referred to as one of the highly reliable and stable means of Javascript-based open source back-end web app framework and one of the world’s most popularized programming language.

Before NodeJS, to load any dashboard would take anywhere approximately 30 seconds. Simply loading the HTML web page itself tooks 10 seconds, then the application would request several other CSS and JavaScript files, each with a response time averaging 5seconds. This was not acceptable clearly so we set about doing everything we could think of to make things rapidly.

Also, NodeJS - the great tool for running and creating application logic that produces the core, variable content for your web application. But it is not so great for serving static content - Images and JavaScript files, For Example - or load balancing all over multiple servers.

This blog represents some tips that are known to speed up your NodeJS web app development tremendously. So let’s see each of them.,

Run in Parallel

To provide the HTML page for any dashboard, the NodeJS app needs to receive ample amount of data for the dashboard. We need to make multitude internal API calls to fetch diverse data. Since the NodeJS is perfectly suited to execute multiple asynchronous functions in parallel, and since lot of these internal API requests did not rely on each other, it made sense to parallelize them - fire off all the requests at once and then continue once they have all completed. 

Cache, Cache, Cache

Unlike most server-based apps, NodeJS apps execute permanently. You can set frequently-used variables such as Database connection objects once and re-use them during every request for every user. The conceptualization can be extended as necessary. Generally, the more high-use items you can cache the better performance will be. 

Enable GZIP

Turn on GZIP compression can impact the execution of your web application massively. When a GZIP compatible browser requests for some resource, the server can compress the response before sending it to the browser. If you don’t use GZIP for compressing your static resource it might take longer for the browser to fetch it.

Use NGINX in Front of Node

Nginx is small and lightweight web server that can be used to eliminate the load on your NodeJS server. Rather than serving static files from Node, you can configure nginx to serve static content. Also you can setup nginx to compress the response of the code using gzip so that the overall response size is tiny. So, if you are executing a production app you might want to utilize nginx to enhance the speed.

Summing Up

This article describes some of the most crucial performance improvements you can make in your application with NodeJS Development Company. Even after all these optimizations and tweaks, we are well aware that there’s still plenty of room for improvement. Especially on mobile, where CPU power, memory, rendering performance, latency and bandwidth are all crucially more limited tan they are on the desktop.
