Some basic rules and best practices for Vue naming

Vue is a progressive framework for building user interfaces and is widely used in web development. Naming is a very important issue during the development of Vue applications. A good naming scheme can improve the readability, maintainability, and scalability of your application. This article will introduce some basic rules and best practices about Vue naming.

1. Component name naming rules

In Vue applications, components are the basic unit for building interfaces. Therefore, there are some basic rules to follow when naming Vue components:

• The component name must be one word (strictly kebab-case).
• Component names should be meaningful and reflect the function of the component.
• Component names should be concise yet clear.
• Component names should not contain special characters such as $ or _ (except $refs).

The following is an example of a component that conforms to the naming rules:

Vue.component('my-component', {
  // 组件选项
})

2. Prop name naming rules

Prop is a method of communication between components way. In Vue, Props pass data to child components through parent components. In order to maintain the readability and maintainability of the application, when naming Props, you need to follow the following rules:

• Prop names should use camelCase, consistent with the component name (Vue2.0 There was a limitation of Kebab-Case before. Vue2.0 can accept camelCase later, but it is recommended to be consistent with the component name, that is, Kebab-Case).
• Prop names should be meaningful and reflect the purpose of passing data.
• Prop names should be short, clear, and easy to understand.

The following is an example of Prop naming that conforms to the rules:

Vue.component('my-component', {
  props: {
    message: String //符合命名规则的prop
  }
})

3. Component event name naming rules

In Vue, events are components a way of interaction. When certain events are triggered within a component, the parent component needs to be notified to respond. In order to make the component's event names more readable and maintainable, the following rules need to be followed:

• Event names must be one word (strictly kebab-case).
• Event names should be meaningful and reflect the purpose of the event.
• Event names should be concise and clear.

The following is an example of event naming that conforms to the rules:

Vue.component('my-component', {
  // 父组件监听子组件事件
  template: '<button @click="onClick"></button>',
  methods: {
    onClick() {
      this.$emit('my-event') //符合规则的事件名
    }
  }
})

4. Filter name naming rules

The filter is a component in Vue Common functions for filtering and transforming data. In order to improve the readability and maintainability of filters, the following rules need to be followed:

• Filter names must be one word (strictly kebab-case).
• Filter names should be meaningful and reflect the purpose of the filter.
• Filter names should be concise and clear.

The following is an example of filter naming that conforms to the rules:

Vue.filter('formatDate', function(value) {
  // 格式化日期
})

Summary

In Vue applications, naming is a very important issue. To improve readability, maintainability, and scalability, basic naming rules and best practices need to be followed. The above rules and examples can be used as guidelines for naming Vue components, Props, events, filters, etc., and can also be flexibly adjusted according to actual situations.
