Vue 3.0 Inline Template Attribute

The inline template attribute in Vue 3.0 allows you to define the template for a component directly in the component's options, rather than in a separate <template> block. This can make it easier to write and organize your components, especially for simple components that don't require a lot of markup.

Here is an example of using the inline template attribute in Vue 3.0:

const MyComponent = {
  template: '<div class="my-component"><h1>{{ title }}</h1><p>{{ message }}</p></div>',
  data() {
    return {
      title: 'Hello World',
      message: 'This is a paragraph'
    }
  }
}

In this example, we define a component called MyComponent that uses the inline template attribute to define the component's template directly in the options. We define a <div> element with a class attribute of my-component, and two child elements: an <h1> element that displays the title data property, and a <p> element that displays the message data property.

We also define a data function that returns an object with the title and message data properties. These properties can be accessed within the component's template using Vue's data binding syntax, {{ }}.

By using the inline template attribute in Vue 3.0, you can define the template for your components directly in the component's options, making it easier to write and organize your code. However, for more complex components that require a lot of markup, it may be more appropriate to use a separate <template> block to define the component's template.

Vue 3.0 Template Attribute:

In Vue templates, attributes are used to bind data, handle events, and manipulate the DOM.
Use the v-bind directive or shorthand : to bind attributes dynamically.

<template>
  <div :class="{ active: isActive }" @click="handleClick">Click me</div>
</template>

<script>
import { ref } from 'vue';

export default {
  data() {
    return {
      isActive: false,
    };
  },
  methods: {
    handleClick() {
      this.isActive = !this.isActive;
    },
  },
};
</script>

Vue 3.0 JSX and Reactivity:

JSX (JavaScript XML) is an alternative syntax for creating Vue components in a more JavaScript-centric way.
Reactivity is maintained in JSX, similar to the template syntax.

<script setup>
  import { ref } from 'vue';

  const isActive = ref(false);

  const handleClick = () => {
    isActive.value = !isActive.value;
  };
</script>

<template>
  <div class={isActive ? 'active' : ''} onClick={handleClick}>
    Click me
  </div>
</template>

JSX Example with Vue 3.0:

<script setup>
  import { ref } from 'vue';

  const message = ref('Hello, Vue 3.0!');
</script>

<template>
  <div>
    <h1>{message}</h1>
    <input v-model={message} />
  </div>
</template>

In JSX, curly braces {} are used for expressions, and reactivity is maintained through ref or other reactive properties.
