rotatable

Subclass of fs.WriteStream that supports automatic file rotations, from multiple parallel processes. Only supports append mode.

Usage

var rotatable = require( "rotatable" );
 
// create a test.log file, and rotate it every 10mb
var stream = rotatable( "test.log", { size: "10mb" } );
stream.on( "rotate", function ( newpath ) {
    // compress and or upload to s3
})
 
// pipe some data into the stream
otherstream.pipe( stream );
 
// or - use it in a Moran log
express()
    .use( morgan( { stream: stream } ) )
