What is the meaning of vue naming

The meaning of Vue naming

Vue is a popular JavaScript framework that has responsive data binding and component-based interface development capabilities. In Vue, naming is very important because it allows us to understand the structure and intent of the code more clearly. In this article, we will delve into the meaning and application of Vue naming.

1. Component naming

In Vue, a component is an independent unit that encapsulates HTML, CSS and JavaScript. A component can contain other components, and each component has a unique name. Component naming should be clear and readable.

For example, we can create a component named MyButton to represent a reusable button. In addition, we can use camelCase notation to represent component names, that is, the first letter of each word is lowercase and the first letter of each word is uppercase.

2. Directive naming

Directive is an important feature in Vue, used to add specific behavior or functionality to DOM elements. There are some Directives built into Vue, such as v-if, v-for, v-bind, etc.

In Vue, we can also create custom Directives for use in specific scenarios. The name of the custom directive should also be clear and readable. For example, we can create a Directive called v-ellipsis to achieve the effect of CSS realistic text ellipses.

3. Props naming

In Vue, a component can receive data or parameters from the parent component through Props. The naming of Props should be clear and readable so that they can be used and understood in components.

For example, in a component named MyHeader, we can add a Props to it, named title, to pass a title.

<my-header title="Welcome to My Website"></my-header>

The names of Props should use camel case naming, such as title, fontSize, textColor, etc. . At the same time, the use of abbreviations or abbreviations should be avoided so that the intent is clearly conveyed in the code.

4. Data naming

The data option in Vue is used to define the internal data of the component. In order to avoid data confusion and conflicts, we should have certain specifications and conventions when naming.

First of all, data naming should use camel case naming, such as userName, userAge, etc. Secondly, we should avoid using the same names as Props in data, otherwise it may lead to data overwriting and confusion.

Summary

In Vue development, good naming conventions can improve the readability and maintainability of the code. Components, Directives, Props and data all need to have certain specifications and conventions in naming so that intentions can be expressed more clearly in the code. At the same time, we can also learn from Vue's official naming convention to improve the quality and structure of the code.
