This web platform allows users to easily and intuitively download audio from YouTube videos in MP3 and WAV formats. The ytdl-core library was utilized to fetch the video's bitstream. For the conversion to MP3 and WAV formats, fluent-ffmpeg was integrated, a library that leverages the FFMPEG tool for the task.
Given that FFMPEG needs to be present on the server, I opted to dockerize the backend. This ensures the tool is available, facilitating hassle-free audio conversion.
