# hls-parser
Provides synchronous functions to read/write HLS playlists (conforms to [the HLS spec rev.23](https://tools.ietf.org/html/draft-pantos-http-live-streaming-23), [the Apple Low-Latency Spec rev. 2020/02/05](https://developer.apple.com/documentation/http_live_streaming/protocol_extension_for_low-latency_hls_preliminary_specification), and [HLS.js's Low-Latency spec](https://github.com/video-dev/hlsjs-rfcs/blob/lhls-spec/proposals/0001-lhls.md))
## Install
[](https://nodei.co/npm/hls-parser/)
[](https://www.jsdelivr.com/package/npm/hls-parser?path=dist)
## Usage
```js
import { parse, types, stringify } from 'hls-parser';
// Parse the playlist
const playlist = parse(textData);
// You can access the playlist as a JS object
if (playlist.isMasterPlaylist) {
// Master playlist
} else {
// Media playlist
}
// Create a new playlist
const {MediaPlaylist, Segment} = types;
const obj = new MediaPlaylist({
targetDuration: 9,
playlistType: 'VOD',
segments: [
new Segment({
uri: 'low/1.m3u8',
duration: 9
})
]
});
// Convert the object into a text
stringify(obj);
/*
#EXTM3U
#EXT-X-TARGETDURATION:9
#EXT-X-PLAYLIST-TYPE:VOD
#EXTINF:9,
low/1.m3u8
*/
```
