How to Optimize The Performance Of Vue

It is quite challenging to develop an application, and most developers do not understand the importance of performance. Hence, they end up building an extensive application that has performance issues. According to statistics, it has been proved that around 53% of the users do not like to spend time on a website that takes more than 3sec to load.

So it is necessary to build an application that will smoothen the user experience and increase user interactions. I agree that it is a challenge to create a fully optimized performance application, and so this blog post will help you understand how you can optimize the structure of the Vue.JS app.

Vue.js is an essential framework for developing websites. If you want to build an extensive scale application or look for performance optimization in Vue.js, this blog will explain all the things in detail.

Vue.js performance optimization

Product owners worldwide develop products for customers, and those users are anxious about their smooth interactions. The end-users do not care about how much effort programmers have invested in Vue JS app architecture if they're now no longer satisfied with Vue js speed and efficiency. Yes, it will become mandatory standards to optimize the overall performance to meet the end-users needs.

Optimizing the performance of Vue.js large application structure:

Below mentioned are the Vue.js performance tips that you can implement for performance optimization

Code splitting based on routes

Lazy loading in vue.js

Vue.js prefetch components

Performance of Vue.js by optimizing third party library

When you take a look at how much is your bundle size and are amazed if it crosses the precise number, it's now no longer always due to what you code; so many times, the cause is the usage of loaded third-party libraries. Yes, all of us use third-party libraries without understanding their effect on our application performance. Our code is probably a tiny part of the bundle size. But before choosing the libraries, you should ask specific questions like:

Why do I want this library?

What is the impact of the library that I chose?

Do I need the whole library for my purpose?

Do I have a performance-friendly way of using the library?

So far, we've handled the bundle size of the VueJS big scale application and VueJS overall performance recommendations for the same. For optimizing overall performance, decreasing bundle size isn't the most effective solution. It'sIt's important to reuse some of the assets so that users don't need to wait. In our next step, let's see how to use the browser cache for reuse.

Using Browser Cache

We have discussed bundle size sufficiently; in this final step, we can focus on caching the data.

Caching is a method of storing selective information to access it quickly when requested.

The browser preserves the data in the memory cache till the browser is not closed.

You can take a look at this by yourself.

Open your developer tool and choose the Network tab. Visit any website and reload it a few times. You'll note that some of the static files like CSS, images, JavaScript, and HTML can have a memory cache, as shown below. This means that such documents are being served from the memory cache.

Conclusion

To conclude, every programmer must be aware of performance optimization tactics to provide user satisfaction, which is the most prominent objective of any Vue.js web application.

The part that worries us is common.[hash].js. We could have all of the dependencies right here, which aren't probably to change often, and we can also use it for caching the data. By separating such components, you're saving your users' time. You can visit right here to read more approximately how to separate the dependencies into exclusive parts.

So, this was Vue performance optimization that can enhance the final performance of your application!
