Según miro, este es todo el objeto req o request o como sea que lo estés haciendo. SI lo esta subiendo, nada más que al directorio que formidable tiene por default osea :: /tmp/:FILENAME como te decía no estas pasando apropiadamente el parámetro del directorio donde se va a subir el archivo. Hace esto en la consola y dime que ves: cd /tmp | ls ahí deben de aparecer los archivos, nada más que con un nombre distinto al original algo como 120ba36bbeb5e3a285c158a00a193bda.

Si aparecen todos en /tmp, ya le asigno el directorio form.uploadDir = './uploads';, pero los sigue colocando en tmp. Imprimo las opciones del formidable.IncomingForm() y si trae la cadena que le indico. Pero al imprimir el objeto upload del request efectivamente me indica que el archivo lo subio al directorio tmp, quiero suponer que primero lo coloca en tmp y despues lo mueve al directorio que se le indica.

No no actua de esa forma, lo sube directamente a la carpeta especificada, lo único que se me viene a la mente es que no existe el directorio uploads o que no tienes permisos para escribir en la carpeta, trata de hacer sudo chown -R $USER ./uploads dentro del directorio del server (para asignarte propietario del directorio), luego imprimi la cadena form: console.log(form) justo luego de haber definido el form.uploadDir y debe de imprimir algo como esto:

{ error: null,
  ended: false,
  maxFieldsSize: 2097152,
  keepExtensions: false,
  uploadDir: './uploads',
  encoding: 'utf-8',
  headers: null,
  type: null,
  bytesReceived: null,
  bytesExpected: null,
  _parser: null,
  _flushing: 0,
  _fieldsSize: 0 }

Ahí podes ver si realmente te esta pasando el parámetro.

@betobaz

Ya encontre por que, en la linea 31, se configura app.use(express.bodyParser());, si comento esta linea ya funciona, ahora a buscar el por que!, Gracias por tu ayuda.
