YTUI - Front end for youtube-dl

Bare minimum zero dependency¹² single binary web app to download youtube videos using youtube-dl. Allows multiple downloads in parallel. Shows title and live download progress. Pull requests welcome. For a more feature full nicer looking app, checkout YoutubeDL-Material

¹Uses golang.org/x/net for websockets. It is strictly not part of go standard library, but still from official go. ²Uses bootstrap for front-end. Files are embedded in the binary, does not make external requests both in front-end and back-end. See CSP header in templates/index.html

Install

❯ go install gitlab.com/balki/ytui@latest

If you don't have and don't want to install go tool-chain, use docker to get the binary

go: downloading gitlab.com/balki/ytui v0.0.0-...

Wrote a small go helper ProgressTracker, to watch for progress and update subscribers. Hope it is useful elsewhere too. It has full unit test coverage
