### Read MP3 Tags in Browser with File API

Source: https://github.com/eidoriantan/mp3tag.js/blob/main/README.md

Demonstrates how to read ID3 tags from an MP3 file selected by a user in a web browser. It uses the modern `file.arrayBuffer()` method to get the audio data and processes it with `MP3Tag`.

```html
<input type="file" id="input-file" accept="audio/mpeg">
<script>
const inputFile = document.getElementById('input-file')
inputFile.addEventListener('change', function () {
  [...this.files].forEach(async (file) => {
    const buffer = await file.arrayBuffer()

    // MP3Tag Usage
    const mp3tag = new MP3Tag(buffer)
    mp3tag.read()

    // Handle error if there's any
    if (mp3tag.error !== '') throw new Error(mp3tag.error)
    else console.log(mp3tag.tags)
  })
})
</script>
```

### Read MP3 Tags in Node.js with fs.readFileSync

Source: https://github.com/eidoriantan/mp3tag.js/blob/main/README.md

Illustrates how to read ID3 tags from a local MP3 file in a Node.js environment using the synchronous `fs.readFileSync` method to obtain the file buffer.

```javascript
const MP3Tag = require('mp3tag.js')
const fs = require('fs')

const buffer = fs.readFileSync('/path/to/audio.mp3')
const mp3tag = new MP3Tag(buffer)

mp3tag.read()

// Handle error if there's any
if (mp3tag.error !== '') throw new Error(mp3tag.error)
else console.log(mp3tag.tags)
```

### Read MP3 Tags in Node.js with Blob API

Source: https://github.com/eidoriantan/mp3tag.js/blob/main/README.md

Demonstrates reading ID3 tags from an MP3 file in Node.js using the `node:fs` `openAsBlob` function, which provides an asynchronous, Blob-based approach to file handling.

```javascript
import { openAsBlob } from 'node:fs'
import MP3Tag from 'mp3tag.js'

async function main () {
  const blob = await openAsBlob('/path/to/audio.mp3')
  const arrayBuffer = await blob.arrayBuffer()
  const mp3tag = new MP3Tag(arrayBuffer)
  mp3tag.read()

  if (mp3tag.error !== '') throw new Error(mp3tag.error)
  else console.log(mp3tag.tags)
}

main()
```

### Read MP3 Tags in Browser with FileReader

Source: https://github.com/eidoriantan/mp3tag.js/blob/main/README.md

Shows an alternative method to read ID3 tags from an MP3 file in a browser using the `FileReader` API. This approach is useful for older browsers or specific file handling scenarios.

```html
<input type="file" id="input-file" accept="audio/mpeg">
<script>
inputFile.addEventListener('change', function () {
  const reader = new FileReader()
  reader.onload = function () {
    const buffer = this.result

    // MP3Tag Usage
    const mp3tag = new MP3Tag(buffer)
    mp3tag.read()

    // Handle error if there's any
    if (mp3tag.error !== '') throw new Error(mp3tag.error)
    else console.log(mp3tag.tags)
  }

  if (this.files.length > 0) {
    reader.readAsArrayBuffer(this.files[0])
  }
})
</script>
```
