This is a fork of eugeneware/fs-tail-stream that fixes an encoding issue.
Switch back to the original when https://github.com/eugeneware/fs-tail-stream/pull/2 is merged and released.
fs.createReadStream
that supports ongoing tailing of files
The built in fs.createReadStream
function stops streaming once the file has
come to an end.
If you want to tail the file so that it keeps streaming data when the file grows
then you're out of luck.
This module adds a { tail: true }
option to the options which will keep
streaming data as data is added to the file, or until the .close()
method
is called on the read stream.
Because this module wraps the underlying fs.createReadStream
function all
the options work as expected.
Installation
This module is installed via npm:
$ npm install fs-tail-stream
Example Usage
var fst = require('fs-tail-stream');
var fs = require('fs');
var ws = fs.createWriteStream(tmpFile, { flags: 'a' });
var tmpFile = '/tmp/my-temp-file.txt';
fst.createReadStream(tmpFile, { encoding: 'utf8', start: 80, tail: true })
.on('sync', function () {
var self = this;
ws.write('world', 'utf8', function (err) {
self.close();
});
})
.on('data', console.log);
