In this video training, you’ll learn how to create Video Streaming server in Node JS.

Streams:

Videos work by streaming. This means that, instead of sending everything to the front end in a single package, you should send it in little chunks at a time.

Getting the file size: fs in Node has a method called statSync that will return the stats of a file. Among those stats, it’s the file size we need to know when the currently loaded chunk has reached the end of the file. You can also use stat — in my case, I tried to avoid synchronicity to try and keep the code easier to understand for newcomers.

Creating a stream from a file: fs contains another method called createReadStream which will create a stream given a file, the start and end chunks.

const fileChunk = fs.createReadStream(sample.mp4, {start, end});
