last-line-stream
A PassThrough stream that keeps track of last line written.
Install
$ npm install --save last-line-stream
Usage
const lastLineStream = require('last-line-stream');
const stream = lastLineStream();
stream.write('foo');
assert(stream.lastLine === 'foo');
stream.write('bar');
assert(stream.lastLine === 'foobar');
stream.write('baz\nquz');
assert(stream.lastLine === 'quz');
API
lastLineStream([pipeTo])
Returns a new instance of the spying PassThrough stream,
pipeTo
Type: stream
If supplied, the new instance will automatically be piped to this stream.
stream.lastLine
Type: string
The last line written out to this stream. The lastLine value will grow until the stream sees a newline character ('\n').
Low Level API
A low-level non-stream based API is available. It has only two methods.
var createTracker = require('last-line-stream/tracker');
var tracker = createTracker();
// append some text.
tracker.update(someString);
// Find the complete last line of all the text appended.
tracker.lastLine();
