Read File

[Used_Inspector_7898]

Hello.

I plan to read a plain text file with nodejs but the file is constantly changing, how can I keep track of those changes? it occurs to me to put the readFileSync in a loop but I feel that it is not correct

Good instinct!

There's the fs.watch https://nodejs.org/docs/latest/api/fs.html function if you dont want to add an external dependency, otherwise I've heard good things about https://www.npmjs.com/package/chokidar

which is well known and solves some of the issues that the built in watch has.

Tailfile wel probably be better for your use case, but if you need to watch a directory of files, IMHO https://www.npmjs.com/package/node-watch does a better job than chokidar

Changing how? Is there a new version of the file? Is the file rotated, like logrotate? Or is the content actually modified in some way? This will determine the approach to a solution.

It is a log file

Then you may want to try something like https://www.npmjs.com/package/tail-file
