theia is a youtube downloader application with built-in music piracy support. it even features the prettiest damn gradients of any downloader ever seen.
"how's she doin'?" i'm so glad you asked! why don't you see for yourself! 
this app is currently in prerelease, meaning that main branch code is, well, dated. releases are built from the prerelease branch and development happens on the dev branch. i strongly advise you to NOT build from the main branch while the app is in it's prerelease stage. again, the main branch will NOT be updated until the app is ready for full release, so please direct your beautiful eyes to the prerelease branch, thanks!
this code is MESSY! this was intended as a personal exercise to learn svelte and electron, so please note this was my first time working with these tools. however, should you want to, pr's are always welcome.
i'm also currently a student, which restricts the time i have to "manage" this repo, meaning it may take me a bit to respond to your issue/pr.
happy hacking, and may your illegally downloaded music library remain ever growing!
any mentions of music piracy are intended as humour, not to encourage media piracy by any means. buy music, support artists.
