periodic-read v0.0.8

Installation

npm install periodic-read

Usage

Read file every 500ms and print result to the console

PeriodicRead = require('periodic-read').PeriodicRead

pr = new PeriodicRead('/var/log/syslog')

pr.on('line', function(linetext) {
    console.log(linetext);
});

pr.on('error', function(err) {
    console.log("FAIL:", err)
});

Options

Different separator

If your special case requires line to be separated by something different than \n, you can specify new line separator as second line argument. For example if every line begins with '2014' and you want to use it as separator:

pr = new PeriodicRead('/tmp/something.txt', '2014')

Read interval

By default, PeriodicRead will read file every 500ms, but this can be changed by providing number of miliseconds to wait as interval argument. Example:

pr = new PeriodicRead('/var/log/security.log', '\n', 2000)

Credits

This project is heavily insipred by node-tail created by Luca Grula. The main difference is that file is not being observed through linux kernel, but it's forcibly read every 500 ms by default.
