  '}'+
  '#tableContainer-1 {'+
    'height: 100%;'+
    'width: 100%;'+
    'display: table;'+
  '}'+
  '#tableContainer-2 {'+
    'vertical-align: middle;'+
    'display: table-cell;'+
    'height: 100%;'+

'</div>'



//sails.log("html template------->"+template);



 var options = {
       "height": "5.5in",
       "width": "8in",
        "format": 'Letter',
        // Page options
        "border": {
    "top": "2in",            // default is 0, units: mm, cm, in, px
    "right": "1in",
    "bottom": "2in",
    "left": "1.5in",
    "type": "pdf",             // allowed file types: png, jpeg, pdf 
    "quality": "75",
  "directory": "/tmp"
  },};


    htmltopdf.create(template, options).toFile('rentreceipt.pdf', function (err, file) {

        if (err) {
            return next(err);
        } else {
            console.log(file);
            res.json({filepath: file.filename}); 
        }
    });



}

The above code is my controller.js file which is not downloading the file.But it was storing the file in my sails app as shown in above picture.

Answer 1

If you want to use this controller to download the file directly. You can use the skipper-disk package with sails https://www.npmjs.com/package/skipper-disk .

Then rather than

htmltopdf.create(template, options).toFile('rentreceipt.pdf', function (err, file) {
  if (err) {
    return next(err);
  } else {
    console.log(file);
    res.json({filepath: file.filename}); 
  }
});

You could quickly install skipper-disk

npm install skipper-disk --save

Then change your code to this

htmltopdf.create(template, options).toFile('rentreceipt.pdf', function (err, file) {
 if (err) {
   return next(err);
 } else {
   console.log(file);

   // including skipper-disk
   var SkipperDisk = require('skipper-disk');
   var fileAdapter = SkipperDisk();

   // using the fileadapter to pipe the response
   fileAdapter.read(file.filename).on('error', function (err) {
     return next(err);
   }).pipe(res);
  }
});
