An Improved Node.js Wrapper for YoutubeDL

youtube-dl conventionally makes it very hard to get progress information on the status of a download. This module
implements a new function download which returns a ProgressPromise. This promise allows you to get the
status of the download, but also implements a progress method for you to be informed of the file's size and
download progress.

$3

See youtube-dl-exec
for a listing of the arguments which can be passed to youtube-dl.

$3

We also accept an options object which only has a single option at the moment:

- timeout: How many ms after which we should abort the download. Set to false to never timeout.

``javascript

const { download } = require('youtube-dl-progress-improved')

const promise = download("https://www.youtube.com/watch?v=dQw4w9WgXcQ", {
// youtube-dl options go here:
format: 'bestvideo[height <=? 480]+bestaudio/best[height <=? 480]',
}, {
// our options go here, currently that's only:
timeout: 60 * 1000,
})

promise.progress((value) => {
console.log(value.percentage, value.totalSizeBytes, value.timeRemainingSeconds, value.rateBytesPerSecond)
})

promise.then(() => {
console.log("Download completed")
}, (err) => {
console.error("Error downloading", err)
})

// You can also cancel a download:
promise.cancel()

// A cancelled download will reject, but promise.cancelled will be true
