Quickstart

Before you begin

1. Setup an API key

Installing the client library

// npm
npm install voice-rss --save-dev

// yarn
yarn add voice-rss --dev

Initiate the client library

// Imports the Voice RSS client library: es6 import (alternative 1)
import VoiceRSSWebApi from './voice-rss-api';

// Imports the Voice RSS client library: require (alternative 2)
const VoiceRSSWebApi = require('./voice-rss-api');

// Instantiates the client
const VoiceRSS = new VoiceRSSWebApi();
VoiceRSS.setApiKey('API_KEY');

// Instantiates the client with an api key
const VoiceRSS = new VoiceRSSWebApi('API_KEY');

Using the client library

Here are three examples of how to use the client library

// callback implementation
// the second argument is the options
// see "Default options" section below for available options and for setting options all at once
// see "Setting options" section below to set options one by one
VoiceRSS.getAudio('Hello World', {}, (err, audio) => {
    if (err) console.error(err);
    else new Audio(audio).play();
});

// promise implementation
// you can pass the options as the second argument, as in the callback implementation
VoiceRSS.getAudio('Hello World')
    .then(audio => new Audio(audio).play())
    .catch(error => console.log(error));

// async/await implementation
// you can pass the options as the second argument, as in the callback implementation
(async () => {
    const audio = await VoiceRSS.getAudio('Hello World');
    
    // play the audio
    new Audio(audio).play();
    
    // OR console log the audio (base64 encoding)
    console.log(audio);
})();

Setting options

VoiceRSS.setApiKey('API_KEY');
VoiceRSS.setLanguage('en-us');
VoiceRSS.setSpeechRate(0);
VoiceRSS.setAudioCodec('auto');
VoiceRSS.setAudioFormat('44khz_16bit_stereo');
VoiceRSS.setSSML(false);
VoiceRSS.setB64(false);

Getting options

VoiceRSS.getApiKey();
VoiceRSS.getLanguage();
VoiceRSS.getSpeechRate();
VoiceRSS.getAudioCodec();
VoiceRSS.getAudioFormat();
VoiceRSS.getSSML();
VoiceRSS.getB64();

Default options

const options = {
    hl: 'en-us',
    r: 0,
    c: 'mp3',
    f: '44khz_16bit_stereo',
    ssml: false,
    b64: false,
};
