How to keep track of a updating csv file in nodejs

Question

I'm using websockets in NodeJS to create a server and I want to read a CSV file or parse a CSV file and print data on a web page but that file is updated frequently so is there a way to keep track of the updating file and print the updated data like appending the print data whenever updated?

Answer 1

Have a look at using fs to watch a file for changes .

When this event fires for your file, you can send a socket event with the latest version of the contents of the file to the client. You will need to re-fill your file stream when this event fires, and then send the results over the socket.
