In a Vue.js application there may be data or utilities that are used in many components, but you don’t want to change its scope and keep its value same for all the components. These types of variables are called the global variables. In such cases, the user can use the following syntax for defining the prototype − Vue.prototype.$appName = 'My App' Now this $appName will be available on all the Vue instances, even before creation. The $ defined before the appName is the convention used for properties that are available to all the instances. The user can also ... Read More

The javascript attribute names are case insensitive, so browsers are made in a way to interpret any uppercase characters to lowercase. This means, while using the DOM elements, camel Cased props names need to use their kebab-based (hyphen-delimited) equivalents. So let’s say that you are not sure of the type of value you might receive from the props in Vue.js. Usually, you will want every prop to have a specific type of value. But in a case when you want a prop to have a list of value types, you can use the following syntax to apply the same. props: ... Read More

Vue can be defined as a progressive framework for building user interfaces. It has multiple directives that can be used as per the user needs.

This process of adding elements into an Array can be used in real life in different scenarios. For E.g.: It can be used for creating a shopping ... Read More

Let’s say you have two nested components i.e. a component inside another component. How will you be able to access the child methods from the parent? To access the child method from the parent method you could use ref. Or you can also access the descendants of a parent via the method this.$root (a parent component) which can access the child components using the this.$children array. In the same way, the child can access its parent via the this.$parent. The vue.js basically warns against these for the below two reasons − It tightly couples the parent to the ... Read More

The difference between a computed property and a method is that computed properties are cached, these properties only change when their dependency change. A method will be evaluated every time it is being called. The only useful situation is when the user wants the getter and needs to have the same parameterized. The same situation occurs in vuex also. Example Copy and paste the below code snipped in your Vue project and run the Vue project. You shall see the below output on the browser window. FileName - app.js Directory Structure -- $project/public -- app.js ... Read More

Vue can be defined as a progressive framework for building the user interfaces. It has multiple directives that can be used as per the user needs. The basic core library is mainly focused on building the view layer only and is also easy to pick up other libraries or integrate with them. We can dynamically add or remove elements from a list in VueJS using the v-model directive. All the possibilities are binded to a single channel while using this directive. When the user selects an option out of several options, the same will be added to the list. On ... Read More

Vue JS is an open-source JavaScript framework. It is used to create single-page apps and user interfaces. The component-based architecture of Vue Js uses separated, reusable elements called components to encapsulate HTML, JavaScript, and CSS. This enables the usage of a virtual DOM to boost performance while also helping efficient and maintainable code. Vue Js’s reactivity system, which allows it to immediately refresh the user interface when the underlying data changes, is one of its distinguishing characteristics. The “v-for” directive in Vue Js renders elements from iterating over arrays or objects based on the item looped over. Depending on the ... Read More

The process of assigning URLs to components in the Vue.js app is known as routing. Installing the Vue-router library and importing it into the Vue instance are prerequisites for implementing routing. Then, the user must specify the components displayed for each route in a different router.js file after defining a set of routes. Users may specify where the components for each route should be displayed in the main Vue template using the “router-view” component, and also, the users can switch between routes using the “router-link” component. A clicked link created by the routerlink component alters the URL and modifies ... Read More
