fs.watch fired twice when I change the watched file

Question

 fs.watch( \'example.xml\', function ( curr, prev ) {
   // on file change we can read the new xml
   fs.readFile( \'example.xml\',\'utf8\', function ( err, data ) {         


        

Answer 1

1. is unstable
2. has known "behaviour" with regards repeated notifications. Specifically, the windows case being a result of windows design, where a single file modification can be multiple calls to the windows API
