How to use vue indicator

Vue indicator is a component used to display page loading or processing progress. It's very useful because it provides feedback telling the user what they are waiting for and how long they need to wait. In this article, we will introduce how to use Vue indicators.

1. Install Vue Indicator

Before you start using Vue Indicator, you need to install it. There are several options available, depending on your project requirements and needs. One option is to install via the npm package manager.

Run the following command in the terminal to install vue-spinner:

npm install vue-spinner --save

If your project uses yarn as the package manager, you can also use the following command to install:

yarn add vue-spinner

2. Introducing Vue Indicators

Once vue-spinner has been installed, you now need to introduce it in your Vue component. You can introduce it in a specific component, at the page level, or in the app's entry file.

Normally, you can introduce it in the script tag, like this:

<template>
  <div>
    <BounceLoader />
  </div>
</template>

<script>
import { BounceLoader } from 'vue-spinner'

export default {
  components: {
    BounceLoader
  }
}
</script>

In this example, we used a very simple container div in the template and added the BounceLoader . In the script tag, we first clearly indicate that we are referencing vue-spinner’s BounceLoader component. We then add it as a component to our current component.

3. Use in the page

After introducing vue-spinner in your Vue component, you can now use it directly in the template. We will show an example here where the BounceLoader component is used. This is a very nice animated loading indicator that will appear when other content is loading.

<template>
  <div>
    <BounceLoader />
    <p>内容正在加载，请稍候...</p>
  </div>
</template>

In this code, we wrap the BounceLoader component in a simple div and add some descriptive text below it to tell the user what it is loading.

This is simple, you can use more complex indicators instead of just BounceLoader if needed.

4. Customizability of Indicators

Vue indicators are highly customizable. You can customize the indicator's size, color, speed, etc. by setting different parameters. The following are some commonly used parameters:

Name	Type	Default value	Description
size	Number	35	The size of the indicator in pixels
color	String	'#1A8FFF'	The color of the indicator
margin	String	'auto'	Indicator margin value
radius	Number	0	Indicator Corner Radius
loadingText	String	'Loading...'	Whether the indicator displays text prompts
loadingTextStyle	Object	{}	Customizable text style

If you want your indicator to look cooler, you can add custom styles to your component. In this example, we added the following style to the BounceLoader indicator:

<template>
  <div class="loading-container">
    <BounceLoader 
      :size="50" 
      :color="'#FFA500'" 
      :margin="'20px'" 
      :radius="10" 
      :loadingText="false" 
      :loadingTextStyle="textStyle" 
    />
  </div>
</template>

<script>
import { BounceLoader } from 'vue-spinner'

export default {
  components: {
    BounceLoader
  },
  data: function() {
    return {
      textStyle: {
        fontSize: '20px',
        color: '#FFA500'
      }
    }
  }
}
</script>

<style>
.loading-container{
  display: flex;
  align-items: center;
  justify-content: center;
  height: 100vh;
}
</style>

In this example, we first define a div container surrounding the BounceLoader component and define a style for it. We set the height to 100vh and centered the BounceLoader component using flexbox layout. We also set some custom properties used, such as size, color, margins, etc.

To sum up, Vue indicators are a very useful tool to let your users know what is going on. Vue indicators come in many different styles and sizes, suitable for use in various types of projects. You can customize your indicator using custom properties to achieve a look that matches your design style.
