VTT Parser

Install

npm i @polyflix/vtt-parser

How to use

This module allows you to parse a VTT file from a raw file, or from an URL. Once the file is parsed, you'll have access to some methods like getBlocks to get an array of the subtitles present in the file.

Below an example for parse a VTT file from an URL :

import { VttFile } from '@polyflix/vtt-parser';

const url = "https://www.iandevlin.com/html5test/webvtt/upc-video-subtitles-en.vtt"

const file = await VttFile.fromUrl(url);

// To get the parsed subtitles :
file.getBlocks()

In this example, JSON.stringify(file.getBlocks()) returns to you the following JSON string :

    "endTime": 5000,
