                ques_file.upload({ 
                  saveAs: function(file, cb) {                       
                            cb(null, file.filename);
                          },
                  dirname: dirPath },function (err, files) {
                  if (err){                        
                    return res.serverError(err);
                  }else{                     
                    name =files[0].filename;

Answer 1

you should not use if statement for req.file() , you can check the length of array inside the function whenDone as in example below:

req.file('avatar').upload({
      saveAs: function(file, cb) {
        cb(null, file.filename);
      },
      dirname: uploadPath
    }, function whenDone(err, uploadedFiles) { //onUploadComplete
      if (uploadedFiles.length==0) {
        //if no file selected.
        sails.log.info('nothing selected');
        return res.view('showimage');
      }
      if (err){
        return res.serverError(err);
      } else{
        return res.view('showimage', {file:uploadedFiles});
      }
    });

Answer 2

Try installing 0.5.5 of Skipper- the default ETIMEOUT timer was extended. Also in past versions, ETIMEOUT issues for many users were coming from multiparty form upload errors (ie unknown content-type) that were getting eaten by the ETIMEOUT.

To install skipper@0.5.5, you can directly bring it in as the bodyparser in your project by doing npm install skipper --save in your project and configuring it as middleware , or you can just install Sails v0.11.x, which comes with the updated version.

As of today, Sails v0.11 is released with the "beta" tag on npm, so you can install it directly in your project using:

npm install sails@beta --save
