Question about using hls-server on the server side

[kenarp]

Hello! I came from your Medium article, which is very helpful to me. But one thing I still couldn't understand well is why do we need the hls-server as a middleware for the serverside? In my practice, I just used the app.use() middleware provided by Express.js to serve the .m3u8 and .ts video files, just like for any other type of files. I wonder if the hls-server provides some features I didn't know, so it should be included? Thank you in advance!
