The progress of Vue3 compared to Vue2: better mobile support

The progress of Vue3 over Vue2: better mobile support

Vue is a popular JavaScript framework for building user interfaces. Vue2 is one of the versions, and Vue3 is its latest released version. Vue3 has made significant progress in mobile support compared to Vue2. In this article, we’ll explore Vue3’s mobile improvements and provide some code examples.

1. Smaller size

Compared with Vue2, Vue3 is smaller in size. This is very important for mobile applications because mobile devices have limited resources. The smaller size can reduce application loading time and improve user experience. The following is an example comparing the volumes of Vue2 and Vue3:

Vue2版本的体积：100KB
Vue3版本的体积：80KB

2. Composition API

Vue3 introduces the Composition API, which is a brand new API style that is more suitable for developing complex mobile applications. . Composition API has better readability and maintainability, making component logic clearer. The following is an example of a counter written using the Composition API:

import { reactive, onMounted } from 'vue'

export default {
  setup() {
    const state = reactive({
      count: 0
    })

    const increment = () => {
      state.count++
    }

    onMounted(() => {
      console.log('Component mounted')
    })

    return {
      state,
      increment
    }
  }
}

3. Better responsive system

Vue3’s responsive system has been greatly improved, providing more efficient tracking and Update mechanism. This is very important for mobile applications because mobile devices have limited resources. The following is an example of an input box implemented using Vue2 and Vue3, demonstrating the advantages of the Vue3 responsive system:

<!-- Vue2版本 -->
<template>
  <input v-model="message" />
  <p>{{ message }}</p>
</template>

<script>
export default {
  data() {
    return {
      message: ''
    }
  }
}
</script>

<!-- Vue3版本 -->
<template>
  <input v-model="message" />
  <p>{{ message }}</p>
</template>

<script>
import { ref } from 'vue'

export default {
  setup() {
    const message = ref('')

    return {
      message
    }
  }
}
</script>

As you can see, the ref function is used in Vue3, which provides better performance and more conciseness syntax.

To sum up, Vue3 has made significant progress in mobile support compared to Vue2. It has smaller size, better Composition API and responsive system. These improvements make Vue3 a better choice for developing mobile applications. If you are developing mobile applications, you may consider using Vue3 to improve your development efficiency and user experience.
