  1. Hi! I've found an obsolete property name in tutorial Node.js Upload Files: files.filetoupload.path Attempts to call it throw an error. Today the right property name will be the next: files.fileUpload.path I think it should be fixed so as not to disorient beginners. Thanks!

    Problem with callback.

    Hello. I have a problem with a function that contains a callback. The problem is, when I execute it the first time, it works without no problem, but the second time, the callback is executed twice: first with the first value and later with the second value. I post the code and an example of running Code of the function: function titulo(terminoTitulo) { console.log("titulo():"); console.log("titulo(): Fuera del callback: " + terminoTitulo); consultar_titulo(terminoTitulo, function (titulo) { console.log("titulo(): termino: " + terminoTitulo); console.log("titulo(): Dentro del Callback"); console.log("titulo(): "+titulo.length); }); Code of the proxy that receives the parameters and calls to a nodejs server: function consultar_titulo(titulo_consulta, callback) { var socket = io.connect('http://localhost:8080'); socket.emit('consultar_titulo', { "titulo_consulta": titulo_consulta }); console.log("proxy(): Emitida la consulta"); socket.on('respuesta_consultar_titulo', function (data) { console.log("proxy(): Estoy en el proxy dentro del callback"); callback(data.respuesta_emit); });} //consultar_titulo() Example of running. titulo():titulo(): Fuera del callback: bbb proxy(): Emitida la consulta proxy(): Estoy en el proxy dentro del callback titulo(): termino: aaa titulo(): Dentro del Callback titulo(): 0 proxy(): Estoy en el proxy dentro del callbacktitulo(): termino: bbb titulo(): Dentro del Callbacktitulo(): 0 In this example the first time, the user introduced "aaa", and the second time "bbb". As can see, the function is called once but when the callback is executed two times. Regards
