Vue is intended to be performant for the majority of typical use cases with little manual tuning. However, there are always challenging situations that need more fine-tuning. This part will explore the performance considerations you should keep in mind while developing a Vue application.

This article will examine recommended practices, dangers to avoid, and some handy tools that make developing Vue.js code simpler. Vue 2 and Vue 3 can benefit from the best practices we provide.

1. Third-Party Libraries and Performance Tuning

We nearly never use third-party libraries in our applications. This may increase the bundle size and hence slow down our application.

We recently employed the Vuetify component library in a project and observed that the total bundle size was 500kb after minification. This may affect our application’s performance. webpack-bundle-analyzer may be used to determine the size of your app’s bundle.

2. Eliminate or Reduce Slowdown Components

When designing new components from scratch, mainly when importing third-party components, you must verify that their performance is optimal. Using the performance tab of the Vue.js dev tools, you can estimate the rendering time of any element you use. When you add a new component, you may compare its rendering time to that of your current components.

3. Optimize Event Handling

Because not all events are made alike, you must optimize for each one accordingly.

Examples are the mouseover and window scroll events. Even with average use, these two sorts of occurrences may occur repeatedly. If your application’s event handlers execute costly computations, these calculations will be performed numerous times per second, producing latency. Using a debounce function, the number of times these events are handled may be restricted.

Tools that Facilitate Vue Use

When working with Vuejs, we may encounter features that we would want to include but that would be time-consuming to hard-code or challenging. As professional developers, we add tools and auxiliary libraries to simplify our work, and we will examine several of them.

1. Component Library

Component libraries are set of reusable UI components we may utilize in our application to speed up and standardize UI development. Similar to React and Angular, Vue includes component libraries. Included are the following:

Vuetify

This is also a component framework for material design with pre-built code scaffolding, a vast community, and frequent updates.

Buefy

Based on the Bulma CSS framework, this component library is lightweight. If you are acquainted with SASS, it will be simple to use.

Nuxt.Js

After installing VueJS, you should immediately develop a boilerplate to help you avoid writing code from scratch.

NuxtJS enables the creation of many apps, including Single Page Applications (SPA), Progressive Web Applications (PWA), and Server-Side Rendered (SSR), in addition to Static Sites. The system architecture and over 50 modules of Nuxt accelerate the development process.

Nuxt’s bundle analyzer applies VueJS and NodeJS industry standards and improves out-of-the-box speed.

VuePress

It is one of the essential components of the Vue environment and is also known as a dynamic site builder.

Initially, VuePress was created as a tool for creating technical publications. It ultimately evolved into a robust, compact, and small headless CMS. VuePress is a powerful blogging platform with an integrated plugin system.

You may also develop new themes or utilize one of the community’s several pre-made alternatives. The primary benefit of using VuePress is utilizing Vue Parts or scripts without using markdown files.

Quasar

Using the same Vue codebase, Quasar allows the concurrent creation of high-quality, responsive web pages, PWAs, hybrid mobile apps, and Electron applications.

It features over 120 customizable components, ranging from simple to complex, such as schedules, data tables, calendars, WYSIWYG editors, and much more, to match your specific needs.

Quasar is a modular, open-source Vuejs tool designed with best practices in mind. Since mid-2019, it has been reliable and is compatible with Vue versions 2 and 3.

Vue Router

Using routers, we linked the application of URLs to components. Vue-router performs well in this capacity and may be set up as a component-oriented router.

The Vue router provides far more functionality than other frameworks, such as performance components that make switching routes more appealing to users and support connecting with active CSS classes.

Vue-router additionally provides the option of utilizing HTML5 history or hash mode. Because routing affects the user experience, selecting the appropriate tool is essential, especially when the application needs users to travel to previous pages.

2. Validating Library

When designing apps on a broad scale, testing might be crucial. It helps us prevent unneeded bugs while working as a team throughout the development process. Let’s examine the three sorts of testing we may do on our Vue application and the frameworks that enable them.

Conclusion

Regardless of the size of your application, it must be optimized. You are simply one click away from onboarding a VueJS professional to improve your Vue.js application and satisfy your end customers.
