What can replace template in vue

Preface

In the Vue framework, we usually use templates to manage component views. However, in some cases, we want to find a more elegant way to manage component views. This article will Introduce some solutions that can replace template.

1. JSX

JSX is a JavaScript syntax extension that allows us to write HTML-like code in JavaScript, making it easier to manage view elements. In the React framework, JSX has become standard, but in the Vue framework, we can also use JSX to write component views.

Vue provides a vue-loader plug-in, which enables Vue to support JSX syntax. We only need to configure it in webpack and other build tools, and then we can start writing Vue components using JSX.

The following is an example of a Vue component written in JSX:

import Vue from 'vue';

export default {
  props: ['title'],
  render() {
    return (
      <div>
        <h1 id="this-title">{this.title}</h1>
        <p>这是使用JSX编写的Vue组件</p>
      </div>
    );
  },
};

2. Rendering function

In addition to JSX, Vue also provides another solution that can replace template , that is to use the rendering function.

The rendering function is a JavaScript function that returns a virtual DOM. We can use it to dynamically generate component views. The advantage of using rendering functions is that you can program data-oriented, making Vue more flexible and efficient.

The following is an example of a Vue component written using rendering functions:

import Vue from 'vue';

export default {
  props: ['title'],
  render(h) {
    return h(
      'div',
      [
        h('h1', this.title),
        h('p', '这是使用渲染函数编写的Vue组件'),
      ],
    );
  },
};

In the above example, we use the h function provided by Vue to create a virtual DOM node, and then return it to Vue through return To render.

3. Single-file component

In addition to JSX and rendering functions, we can also use another feature provided by Vue - single-file component to manage the view of the component. Single-file component is one of the very important features in Vue. It combines the component's template, script and style into a separate file and packages it through build tools such as webpack, making it easier to manage the component.

The following is an example of a Vue component written using a single file component:

<template>
  <div>
    <h1 id="title">{{title}}</h1>
    <p>这是使用单文件组件编写的Vue组件</p>
  </div>
</template>

<script>
export default {
  props: ['title'],
};
</script>

<style>
h1 {
  font-size: 24px;
  color: red;
}
</style>

In the above example, we write the component's template, script and style in the template, script and style tags respectively , and written through the specification of Vue's single-file components.

Conclusion

The above are three ways to replace the Vue component view. Although template is the default view management method of the Vue framework, other solutions can also be used to achieve more flexible and efficient results. Only by choosing a solution that suits you according to your specific needs can you better take advantage of the Vue framework.
