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

I make allowance for this by doing the following:

var fsTimeout

fs.watch('file.js', function(e) {

    if (!fsTimeout) {
        console.log('file.js %s event', e)
        fsTimeout = setTimeout(function() { fsTimeout=null }, 5000) // give 5 seconds for multiple events
    }
}
