## 💻 Examples
### 1. `getAudioUrl(text, [option])`
```js
import * as googleTTS from '@sefinek/google-tts-api'; // ES6 or TypeScript
const googleTTS = require('@sefinek/google-tts-api'); // CommonJS

// Get audio URL
const url = googleTTS.getAudioUrl('Hello world!', {
  lang: 'en',
  slow: false,
  host: 'https://translate.google.com',
});
console.log(url); // https://translate.google.com/translate_tts?...
```

### 2. `getAudioBase64(text, [option])`
```js
import * as googleTTS from '@sefinek/google-tts-api'; // ES6 or TypeScript
const googleTTS = require('@sefinek/google-tts-api'); // CommonJS

// Get base64 text
googleTTS
  .getAudioBase64('Hello world!', {
    lang: 'en',
    slow: false,
    host: 'https://translate.google.com',
    timeout: 10000,
  })
  .then(console.log) // base64 text
  .catch(console.error);
```

### 3. `getAllAudioUrls(text, [option])` (For text longer than 200 characters)
```js
import * as googleTTS from '@sefinek/google-tts-api'; // ES6 or TypeScript
const googleTTS = require('@sefinek/google-tts-api'); // CommonJS

const results = googleTTS.getAllAudioUrls('LONG_TEXT_...', {
  lang: 'en',
  slow: false,
  host: 'https://translate.google.com',
  splitPunct: ',.?',
});
console.log(results);
// [
//   { shortText: '...', url: '...' },
//   { shortText: '...', url: '...' },
//   ...
// ];
```

### 4. `getAllAudioBase64(text, [option])` (For text longer than 200 characters)
```js
import * as googleTTS from '@sefinek/google-tts-api'; // ES6 or TypeScript
const googleTTS = require('@sefinek/google-tts-api'); // CommonJS

googleTTS
  .getAllAudioBase64('LONG_TEXT_...', {
    lang: 'en',
    slow: false,
    host: 'https://translate.google.com',
    timeout: 10000,
    splitPunct: ',.?',
