FileDuplex

Allows to create a read and write Duplex stream for files. Install it with npm install file-duplex, which is especiall handy for UNIX special files.

Since I didn't find a good way in Node to wait for the read event of the file, there is a timeout specified in case the file returns no bytes to avoid CPU intensive loops. The waiting time of the timeout can be changed through the options attributes readTimeout. It's default value is 50. It's a workaround. It would be nicer to use fs.watch for this, however at least on OSX this doesn't work properly for device files.

Example

var FileDuplex = require('file-duplex');

var file = new FileDuplex('/dev/ttys1');

process.stdin.pipe(file).pipe(process.stdout);
