What is Vue JS Used For?

By now, you must have a crisp and clear idea of VueJS. Plus, you'll be amazed that data collected by BuiltWith depicted that 1,635 200 live websites are using VueJS. Interesting, isn't it?

Speaking of what Vue.JS is used for, you need to know that it is used for desktop and mobile app development. The reason is that it is one of the most heavily favored front-end tools, especially regarding developers. Now a few of you must wonder that there are several frameworks and libraries that the developers can choose from, no? It could be Angular, reach, or Vue!

Well, to be sure, ensure that you pay attention and have a close insight into Angular vs. React vs. Vue so that you make the best choice for your business.

Top VueJS Practices for Developers

If you are looking forward to creating routes for your application and navigating between them, then VueJS is ideal. It'll provide a simple and consistent way to handle routing in your application in the best possible ways. The practices will allow you to keep the code organized and make it easier to understand the structure of your application.

1. Ensure to Use Key Inside V- for

As a Vue.JS API call best practices, remember that using directives and key characteristics together will make your app more consistent and predictable. It is crucial, so keeping track of your parts and having a reliable reference for your various components is practical.

As a developer or company, you must realize that without keys, there is no guarantee about DOM elements' appearance or predictable behavior.

Once again, it is simple to forecast how a Vue application will handle the DOM manipulation if you keep track of and have a key for each component.

Also, we understand that it might just get daunting for you to keep up with the trends and best practices; for the same, you can also rely on a front-end developer, yet again ensure that you have a definitive guide in the hand of how you should hire a front-end developer before you finalize one.

2. Use Vuex Actions

An action in Vuex is in charge of dealing with asynchronous logic and side effects. Before committing modifications to the store, it includes API queries. Additionally, steps may easily handle this task and maintain the code tidy and consistent by replacing sophisticated logic, and API calls directly in the mutation or components.

Understanding the actions is one of the many Vue JS best practices that can help you in the best possible ways to handle asynchronous logic and maintain the application's state.

3. Use Vuex Mutations

To explain this, you must understand that mutations handle synchronous logic, like adding data to the application store's entities and deleting or modifying existing entities' properties.

Making synchronous updates helps your application stay consistent, and all changes are reflected in real time without triggering a re-render. Hence, your components remain light and fast on the client side without unnecessarily facing re-rendering issues.

The best practices allow you to keep the code organized and require you to make changes effectively. In addition, one of the approaches is maintaining an accurate reference to your components and making it easy for you to predict.

4. Stay Consistent -Directive Shorthand

Directive shorthand allows you to keep your code organized. If you find that there is a need for more than one component in the same element, then without further delay, you can use directive shorthand. It will help you to maintain a consistent view of your application. For instance, you can use:

• @ for v-on
• : for v-bind
• #for v-slot

Moreover, this is one of the best practices for developers. They need to be careful whether they use it throughout the project or better not use it from the start. With the help of these practices, you'll be able to make Vue projects more consistent and your code readable.

5. Code Splitting

It is one of the most excellent methods for improving the functionality of web apps. To accomplish this, the code must be divided into smaller units that may be loaded as needed. It can help in the best possible ways to reduce the application's initial load time and help offer a great user experience.

In Vue JS code, spitting can be achieved by lazy loading. Now most of you must wonder what this term is, "lazy loading" Well, it allows you to load the code necessary for a specific route or component instead of loading it upfront.

Take a look at a VueJS application with numerous routes as an illustration. You may quickly eliminate each application's load time by lazy loading each course's components. Now that you're looking into the top practices of VueJS ensure that you do not skip front-end frameworks for your upcoming web projects, as they'll play an equivalent role.

6. Routing

When building a SPA, you must use client-side routing, as it is one of the best Vue router best practices. When it is Vue, you need to know that it does not ship on built-in routing, and the reason behind the same is that it has an official plugin called VueRouter. Additionally, it is simple to use and has all the functions required to create a robust application.

If you use the Vue CLI, you can add it to your application without installing npm-install Vue-router.

To be more explicit, the Vue router facilitates the connection between the URL/History of the browser and the Vue component, enabling particular paths to render whatever view is connected with. The simplest way to create single-page applications is by using a Vue router. You may be wondering at this point how to set up Vue-router. Well, it can be pre-configured when you create a new project.

7. Use Refs Instead of Accessing DOM Elements Directly

Now that we've looked at several practices, you must be well versed that following the best rules regarding Vue is crucial. Plus, avoiding the DOM element directly whenever possible will be great. To access details within the component's template, VueJS instead offers the $refs property. The reactive aspect of Vue.js can be readily maintained by using $refs, and problems that could occur from directly changing the DOM can be avoided.

Also, if you are looking for better encapsulation and easier testing for VueJS, then $refs is what you need to rely on.

Make sure to stay away from direct DOM access, especially while developing the Vue application. It is one of the best ways to access the DOM because it is easier to maintain, and you are not as dependent on specific class names.

8. Add Several Classes to an Element

Making it simple to apply a dynamic class to an element is among the most excellent features of VueJS.

A different yet most common and straightforward approach is;

9. For Event Names, Use the Kebab Case

Use kebab-case when emitting and receiving custom events and listen for them.

It makes it easier to translate the events into lowercase. You must remember that no one listens to an event in CamelCase or PascalCase, so specify the event in a form that will allow you to listen to it in that case.

10. Validate Your Props

You'll find this practice one of the best practices of Vue JS. Recalling the type, format, and conventions used in a prop can be challenging when working on a big project.

So, let's consider an example so that you can similarly write prop validation,

11. Make Use of the Appropriate Structure

Other than when utilizing Nuxt, Vue does not have a default application structure. What does it therefore need? However, it requires that you and your team be well-organized coders. Additionally, designing a system that is easy to grasp is essential because modifying it later is time-consuming and frustrating.

12. Clean Up After Yourself

When you are designing a single-page application, it is essential to build up memory usage. If you do not cut down instances, intervals, or custom events, then there are chances that your app might become slower or even the chances of it being unresponsive multiplied.

13. Avoid Using V-HTML

Using the V-html directive, you can render unprocessed HTML. It may result in security flaws, mainly if user input is not adequately sanitized. You can only sanitize user input using calculated properties or methods, then show the text.

Additionally, if rendering HTML is crucial, you can consider sanitizing the HTML beforehand using a package like DOMPurify.

14. Ensure That You Use HTTPS

By encrypting all data exchanged between the client and the server, HTTPS defends against listening devices and man-in-the-middle attacks. Use HTTPS for VueJS protection and an updated adequately configured SSL certificate.

15. Validate Input from the Users

Validating user input is essential to preventing attacks like cross-site scripting (XSS) and SQL injection. Vue offers computed properties, watchers, and custom directives as alternatives for data validation. It can be applied to ensure user input satisfies a particular requirement.

Features of Vue JS

Now that we have had clarity on the best practices of VueJS, let us walk you through the best features the framework offers. As a progressive JavaScript framework, it has ultimate characteristics.

1. Virtual DOM

The frameworks use virtual DOM. To be more exact, it takes the form of JavaScript data structures and is a clone of the main DOM element that accepts all DOM-related changes. Additionally, a comparison is made between the original data structure and the changes made to the JavaScript data structures.

Additionally, visitors can only see the final modifications as they appear in the real DOM. Its creative mode offers cost-effective solutions, and the changes can be made quickly.

2. Data Binding

With the help of this feature, VueJS manipulates or assigns value to HTML attributes, changes the style, and aligns classes with the use of a binding directive, also referred to as v-bind, available with VueJS.

3. CSS Transitions and Animations

You may apply a transition to HTML elements in several ways with the aid of this VueJS functionality, particularly when they are added, changed, or removed from the DOM. The transition component built within the framework encapsulates the element in charge of returning the transition effect. With that being said, the developers can easily integrate three-party animation libraries and make the user experience a little more interactive and engaging.

4. Template

You should know that VueJS offers HTML-based templates that link the DOM to the VueJS instance data. To create fake DOM render procedures, the templates are merged. Web developers can use the render function templates to replace the template with the render function.

5. Computed Properties

One of the most crucial features offered by Vue JS is this one. The feature ensures that it is attentive to and responsive to changes made to the UI elements, and it executes the necessary logic without further coding.

Ensure utilizing a calculated property when working on a mutation property that depends on another property changing. The logic for the computer property will likewise be activated by any changes made to the dependent property. Additionally, based on their dependencies, the computed attributes are cached, so they only need to be performed again if any dependencies change.

6. Watcher

This feature is applied to data that tends to change frequently, thus easing out the process of a developer. The watcher looks after handling any data changes and helps make the code fast and straightforward.

Components can exploit the reactive nature of Vue JS in three distinct ways. Are you curious to know about those three ways? Well, they are watchers, methods, and computer attributes.

Watchers can be helpful when applying logic due to a change to a particular data attribute. It is beneficial when you must carry out an expensive or asynchronous action in response to changing data.

7. Optimization

The framework is known to keep track of the component dependencies when rendering. It leads to a system that does not need to re-render components when the form changes because it already knows which ones do. To remove any nested component warnings, each element should be able to execute ShouldComponentUpdate.

In a nutshell, Vue JS's advantages include its simplicity and ease of understanding. Due to these advantages, Vue JS is the best option for small and medium-sized businesses (SMEs) and any development company that wants to swiftly construct high-performance online apps with readable code.
