Vue.js App Performance Optimization – Requirement | Top Reasons | Pro Tips/Solutions
Introduction
VueJS is the most popular and stable JavaScript framework for developing websites, but just like other frameworks, the performance will be compromised if you overlook it.
If you are looking for sure shot Vue js performance optimization tips or just want to know vue best practices, for your large scale application you have chosen the correct blog. Without much ado, let’s discuss in detail how you can optimize the performance of Vue js application.
It’s essential first to understand the Vue js app architecture. By knowing its importance, we can be aware of how crucial it is, and we would start taking it more seriously. So, let’s look at why there’s a need to optimize your large scale application. Please keep in mind that optimization of any application is essential, but as this blog concerns, we’ll be discussing it.
Why do we need Vue JS performance optimization?
No programmer will ever want that even after coding thousands of lines, users don’t want to spend time on the application because of the time it takes to perform user actions.
Product owners around the world develop products for users, and these users are mainly concerned with their smooth interactions. It does not concern the end-users how much effort programmers have invested in Vue JS app architecture if they are not satisfied with Vue js speed and efficiency.
So, yes, that is why it becomes mandatory criteria to optimize the performance that will eventually satisfy the end-users’ needs.
Major Reasons Behind Poor Vue Performance
Let’s look at how Vue js works and the significant reasons behind poor Vue performance.
The reasons for slowing down the Vue performance depend upon your Vue js app structure. For example, one of the significant reasons behind poor performance in Vue jS Single Page Applications (SPAs) may vary from the VueJS projects dealing with server side rendering (SSR).
The primary and foremost reason any developer can think of whether the application is SPA or having SSR is bundle size. The larger the bundle size slower the Vue js performance. Thus we can conclude that bundle size is inversely proportional to the application performance.
Some of the common reasons behind Vue js large application-
- Not using third-party libraries wisely
- Overlooking Code Splitting and Lazy Loading
- Unwanted hits to API requests
- Not structuring JS and CSS files properly
