How to use Vue to implement WeChat-like voice message effects

Introduction:
With the development of mobile Internet, voice messages have become one of the important ways for people to communicate in daily life. . WeChat is currently one of the most popular social software, and the voice message special effects experience it provides is deeply loved by users. This article will introduce how to use Vue to implement WeChat-like voice message effects and provide specific code examples.

1. Preparation
   Before we begin, we need to ensure that Vue and related development environments have been installed. You can use the Vue CLI to create a new project or add Vue dependencies to an existing project.
2. Create component
   We first need to create a voice message component named VoiceMessage.vue. This component will be responsible for displaying the icon, duration and special effects of the voice message.

In the above code, we use Vue’s single-file component format, which includes templates, scripts and styles. The voice message component has an icon and a duration label, and the style of the icon can be dynamically changed according to the playback status.

3. Implement playback logic
   In methodplayAudio, we will implement the playback logic of the voice. You can use the HTML5element to play audio. We add an audio object to the component's data and perform corresponding operations in theplayAudiomethod.

In the above code, we first determine whetherthis.audioalready exists. If it does not exist, create a newAudioobject and Pass the path to the audio file. Then determine whether to play the audio or pause the audio based on the status ofplaying.

4. Add special effects
   In order to achieve WeChat-like voice message special effects, we can use the@keyframesrules in CSS. Add the following code to the style.

.icon.active { /* ...略 */ animation: pulse 1s infinite alternate; } @keyframes pulse { 0% { transform: scale(1); } 100% { transform: scale(1.2); } }

In the above code, we define an animation namedpulseto change thetransformproperty of the icon from the initial statescale( 1)changes toscale(1.2), and performs an unlimited number of alternating movements back and forth within 1 second. By adding theanimationattribute to the style of.icon.active, the animation will start running when the icon'sactiveclass is added.

5. Using components
   Now we can use the voice message component we just created in other Vue components.

In the above code, we introduced the voice message component just created throughimportand registered the component incomponents. The component can then be instantiated in the template using thetag.

Summary:
This article introduces how to use Vue to implement WeChat-like voice message effects. By creating a voice message component, implementing playback logic and adding special effects, we can easily implement a WeChat-like voice message experience in the Vue project.
