disk-buffer

Disk buffer as a writable stream, which after n bytes written and/or m writes finishes the file, emits an event and starts writing to a new one.

Example

var DiskBuffer = require('disk-buffer');
 
var b = new DiskBuffer('/tmp/artifacts', {
  flushBytes: 1024,
  flushWrites: 20
});
 
b.on('flush', function(flush){
  // do something with the file at
  // `flush.path`
});
 
someData().pipe(b);

Installation

$ npm install disk-buffer

API

DiskBuffer(path, opts)

Create a new DiskBuffer. The path given is used for the base of the filenames created, which append ".{pid}.{id}.{fid}".

Options:

• .flushBytes: flush after this many bytes written
• .flushWrites: flush after this many writes

flush event

For every flush, an event with the following properties is emitted:

• path: the file's location
• opened: a date object of the file's creation
