Like `tail -f` but a stream. Like fs.createReadStream but keeps reading as the file grows.

File getting truncated with 'beginAt' set to 'end' not always detected #26

Open user58823 opened 3 years ago

When the 'beginAt' option is set to 'end', before the file grows for the first time, no matter how much that file gets truncated, it will not be detected and all new data is completely skipped until the file grows beyond its original size again.

As far as I can tell, you need to add this.lastSize = stat.size; somewhere inside this if-block: https://github.com/Juul/tail-stream/blob/d460a2b46d76325780ab6199b706964a38dace93/index.js#L222

I would gladly accept a pull request but I don't have time to troubleshoot this myself right now :)
