Streams HTTP using RFC-7233 range requests.
Prevents the entire content to be downloaded, for metadata analysis.
This module can be used both in the browser and in Node.js.
Installation
npm install @tokenizer/http
yarn add @tokenizer/http
Example
const mm = require('music-metadata');
const {StreamingHttpTokenReader} = require('streaming-http-token-reader');
const config = {
avoidHeadRequests: true
};
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';
const streamingHttpTokenReader = StreamingHttpTokenReader.from(audioTrackUrl, config);
streamingHttpTokenReader.init()
.then(() => {
return mm.parseFromTokenizer(streamingHttpTokenReader, streamingHttpTokenReader.contentType);
})
.then(metadata => {
console.log('metadata:', metadata);
});
Server requirements
The server needs to send the following headers:
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
