Introduction

In application development, performance is a tricky problem. It's one thing to bring up code and deploy it, and it’s completely another thing to make it quicker and more pleasurable for your customers — and subsequent programmers.

Assume you've spent a long time designing a Vue.js application. Your application currently takes a long time to load, browse, upload, or handle any user activities because you didn't concentrate on its speed.

Visitors will not like the prolonged experience if you have not emphasized efficiency.

We'll go over the measures you can take to ensure your Vue application runs as quickly as possible in this post. So, it is crucial to optimize your Vuejs app for performance. This article includes some great tips to optimize your Vuejs app. So, let's keep digging.

What is the difference between ReactJS and VueJS? Let’s Check it Out!

Not any Vuejs developer wants users to avoid spending time on an app because it takes too long to process user operations, even after hundreds of lines have been written.

Product owners all over the world create goods for consumers who are primarily concerned with flawless encounters. End-users are unconcerned about how much effort developers put into Vue JS app design if the app's functionality, speed, and efficiency are not satisfactory.

Yes, that is why it has become a crucial criterion for Vue optimization to achieve higher performance that will ultimately meet the needs of the end user.

5 methods for optimizing Vue.js applications that every Vuejs developer should keep in mind!

Rendering Vuejs components

One of the most annoying problems with VueJS is displaying the same item or collection of elements more than once. To get why or how this can occur, we must first comprehend Vue's reactivity.

Because the JavaScript Date object is not responsive, it has no bearing on rendering. It will be executed only if we need to render the element again.

What can you expect from a well-optimized page? Only the new or updated components should be shown with a new date, while we tend to ignore other things.

Using elements to render lists improves performance dramatically. Vue will not render all the elements one by one if a component is added or deleted from the array. Vue just rearranges the elements based on the specified key if the array is sorted.

Adopt the lazy loading technique

Lazy loading in Vue js is the technique of uploading components in your application slowly, as the name suggests. When the user browses the page, there's usually no need at all to retrieve all the components from the JavaScript package.

When required, some elements have modals and tooltips that can be packed. If you only have two or three models or tooltips, you won't notice a difference, but if you have a large Vue app with a lot of modals and tooltips, loading them all at once can slow down your application.

It is not necessary to load the complete bundle each time the website loads. As a result, loading assists you in dividing the bundle and loading them when needed. If you do not install all the modules, it saves a lot of time and even optimizes the performance.

In Vue js, lazy loading is among the best techniques for reducing bundle size by 60% and improving performance. Cultivate the practice of understanding which components you don't need unless there's extensive user interaction, and then download them slowly to improve efficiency.

Choose the right packages

With JavaScript's widespread adoption and the huge number of packages released and upgraded on NPM regularly, there's a plugin for almost any Vuejs requirement.

That's fantastic, but we must be mindful not to clutter the size of our program with unnecessary code. A smaller option to a package is nearly always available.

Before searching for a Vuejs module, check to see if the feature you wish to implement is accessible naturally in browsers. A lightweight module is typically the best option if the native feature is inconsistent between browsers or difficult to develop.

When looking for a package, make carefully compare your preferences against the numerous options available. It's also a good idea to pick a package for your project that's constructed in a modular style and accommodates tree-shaking.

Compressing & optimizing the images

Developers must optimize and compress photos appropriately. You should recruit Vuejs developers who are competent at using image compression techniques in Vue.js before hiring them.

There are two options for image optimization. One method is to accomplish it locally, while the other is to use a CDN like Cloudflare.

Local image optimization - If the program simply has a few ideas to display, compressing them locally should work. But the size of the image files must be considered. To maintain the file size within control, the photographs may need to be downsized and compressed.

Image optimization on a CDN - If your app will have a lot of photos, you should use a CDN for image optimization. A CDN has incredible transformation capabilities, allowing image file sizes to be decreased by up to 70%. Even with such high compression, the image appearance is unaffected, and we can avoid pixelation as well.

Pre-fetching components

Pre-fetch elements are components that are downloaded before the user requests the site.

For instance, if you know that the majority of people will come from the category page to the product page, you might consider pre-fetching the product description.

It'll assist if you remember that pre-fetching can only happen after the first render. Another advantage of pre-fetching is that it eliminates the negative repercussions of lazy loading without sacrificing performance.

You only need to add a simple tag to make it work. However, when working with a web pack, which creates bundle names depending on module order, the scenario is unique. Fortunately, the web pack contains magic comments that make pre-fetching a breeze.

We hope that these six methods address the majority of Vue application speed difficulties. No matter how vast a scale program you have created, it will eventually need to be optimized.
