vue-audio-tapir SOURCE

this is a clone of vue-audio-tapir

Audio recorder component for Vue.js 3. It enables to record, play and send audio messages to a server. There is a corresponding serverless backend function called audio-tapir-function. You can use both in combination to send you an email with the recorded audio message.

Demo

Demo page of Audio Tapir, you can record and play audio, but submitting is disabled.

Use Case

The most popular use case of vue-audio-tapir is to deliver an audio contact message directly from a website to your email inbox.

Architecture Overview

The developer includes the vue-audio-tapir component in his Vue 3 website. When the user of the website wants to leave a voice message, he records his message and submits it. Vue-audio-tapir contacts the backend server, a Netlify serverless function and uploads the audio data. The serverless backend function sends the audio data to an email address using the email service Sendgrid. Finally the email with the voice message arrives at the destination, probably the email application of the website owner.

Installation

In a Vue 3 application install with:

npm i vue-audio-tapir-x --save

or

yarn add vue-audio-tapir-x --save

Example Usage

<template>
  <tapir-widget :time="2" backendEndpoint="https://your-endpoint.com/.netlify/functions/audio-message" 
                buttonColor="green" audioFormat="MP3"/>
</template>

<script>
import TapirWidget from 'vue-audio-tapir-x';
import 'vue-audio-tapir-x/dist/vue-audio-tapir.css';

export default {
  name: 'App',
  components: {
    TapirWidget,
  }
}
</script>

Properties

| Name | Type | Description | |------------------|----------|---------------------------------------------------| | time | Number | Maximum recording time in minutes | | bitRate | Number | bit rate of recording | | sampleRate | Number | sample rate of recording | | backendEndpoint | String | URL of the service that receives the data as POST | | buttonColor | String | color code of the buttons for theming | | audioFormat | String | file format of audio recording (MP3 or WAV) | | afterRecording | Function | callback function when recording is finished. | | successfulUpload | Function | callback function that is called when data is uploaded successfully | | failedUpload | Function | callback function that is called when upload failed. |

The data sent to the server is encoded either in the MP3 or WAV format. For MP3 encoding the lamejs library is used.

MP3 encoding saves space but needs more processing power on the client device. WAV has bigger file size but the encoding is faster and needs less power.

Dependencies

• Vue 3
