A modern ID3 parser written completely in JavaScript, making use of typed arrays and the HTML5 File API
npm install id3jsid3.js is a JavaScript library for reading and parsing ID3 tags of MP3
files.
It can parse both ID3v1 and ID3v2 tags within a browser or within Node.
Files can be read from the local disk (Node only), same-origin URLs
and File instances (HTML5 File API).
Install:
``
$ npm i -S id3js
You may parse ID3 tags of a remote MP3 by URL:
`html`
This works by sending a HEAD request for the file and, based on the response,Range
sending subsequent requests for the ID3 tags.
This is rather efficient as there is no need for the entire file to be
downloaded.
You may parse ID3 tags of a local file in Node:
`ts
import * as id3 from 'id3js';
id3.fromPath('./test.mp3').then((tags) => {
// tags now contains v1, v2 and merged tags
});
`
**Keep in mind, Node must be run with --experimental-modules
for this to be imported and it cannot be used with .**
You may parse ID3 tags of a file input:
`html
`
This will read the data from the File instance using slices,
so the entire file is not loaded into memory but rather only the tags.
An MP3 may have images embedded in the ID3 tags. If this is the case,
they can be accessed through the tag.images property and will
look like so:
`json`
{
"type": "cover-front",
"mime": "image/jpeg",
"description": null,
"data": ArrayBuffer
}
As you can see, the data is provided as an ArrayBuffer.DataView
To access it, you may use a or typed array suchUint8Array`.
