m3u8-file-parser
Advanced tools
A m3u/m3u8 file parser build against RFC8216 specs.
npm install m3u8-file-parser --save or yarn add m3u8-file-parser
In Node.js
const M3U8FileParser = require('m3u8-file-parser');
const fs = require('fs');
const content = fs.readFileSync('./example.m3u8', { encoding: 'utf-8'});
const reader = new M3U8FileParser();
reader.read(content);
reader.getResult(); // Get the parse result
reader.reset(); // Optional, If you want to parse a new file, call reset()
In Node.js read line by line
const M3U8FileParser = require('m3u8-file-parser');
const fs = require('fs');
const content = fs.readFileSync('./example.m3u8', { encoding: 'utf-8'});
const readline = require('readline');
const reader = new M3U8FileParser();
const stream = fs.createReadStream('./example.m3u8', { encoding: 'utf-8' });
const interface = readline.createInterface({ input: stream });
interface.on('line', line => reader.read(line)); // Read line by line
interface.on('close', () => reader.getResult()); // Get result after file ends.
In browser, use the file in dist instead.
