@tokenizer/http

Specialized strtok3 tokenizer for HTTP(S) RFC-7233 range request transfer.

The range request will ensure only the data is downloaded, which is actually being read, and data ignored will not be downloaded.

The range request mechanism is derived from @tokenizer/range.

Installation

Install using npm:

npm install @tokenizer/http

or using yarn:

yarn add @tokenizer/http

Usage

Configuration options

  • resolveUrl, boolean, default value is true. Enable caching of redirects of HEAD requests.

Example

// const mm = require('music-metadata-browser');  // Use module 'music-metadata-browser' client side
const mm = require('music-metadata'); // Use module 'music-metadata' in Node.js
const {makeTokenizer} = require('@tokenizer/http');
 
const audioTrackUrl = 'https://test-audio.netlify.com/Various%20Artists%20-%202009%20-%20netBloc%20Vol%2024_%20tiuqottigeloot%20%5BMP3-V2%5D/01%20-%20Diablo%20Swing%20Orchestra%20-%20Heroines.mp3';
 
(async () => {
  const httpTokenizer = await makeTokenizer(audioTrackUrl);
  const metadata = await mm.parseFromTokenizer(httpTokenizer);
  console.log('metadata:', metadata);
})();

Server requirements

The server needs to send the following headers:

HTTP header- Value
Access-Control-Allow-Origin "*"
Access-Control-Allow-Methods "GET,HEAD,OPTIONS"
Access-Control-Allow-Headers "Content-Type, Range"
Access-Control-Expose-Headers "Content-Length, Content-Range"

Example configuring Apache for streaming. Add the following to .htaccess in the folder sharing your audio tracks:

Header set Access-Control-Allow-Origin "*"
Header set Access-Control-Allow-Methods "GET,HEAD,OPTIONS"
Header set Access-Control-Allow-Headers "Content-Type, User-Agent, If-Modified-Since, Cache-Control, Range"
Header set Access-Control-Expose-Headers "Content-Length, Content-Range"

Ref:

Try if range request is supported:

curl -v -L --header "range: bytes=1-8" http://localhost:8080/bbb/test
