Sails.js - file upload

I am working on a Sails.js project at the moment and I would like to upload a file to the server and save the link to that file in my database.

For example, when I click add FILE, it should allow me to select a file from my computer and when I click submit, it should upload the file to the URL that I point ( create the folder if it does not exist).

Can this be accomplished with Sails.js? If yes, how?

Thank you!

The best option is to do this on middleware

aware to check filetypes and route matching otherwise bad actors can upload malicious files

Edit config/http.js like this

serverOptions: {
    timeout: 600000,
  },
  middleware: {

    /***************************************************************************
    *                                                                          *
    * The order in which middleware should be run for HTTP requests.           *
    * (This Sails app's routes are handled by the "router" middleware below.)  *
    *                                                                          *
    ***************************************************************************/

    order: [
      'cookieParser',
      'session',
      'bodyParser',
      'fileUpload', //new middleware
      'compress',
      'poweredBy',
      'router',
      'www',
      'favicon',
    ],

fileUpload middleware code

fileUpload: (function () {
  return function (req, res, next) {
    console.log('Received HTTP request: ' + req.method + ' ' + req.path);
    const uploadRoutes = ['/save-user-profile-image'];
    if (req.method === 'POST' && uploadRoutes.includes(req.path)) {


      req.file('profileImage').upload(
        {
          maxBytes: 10000000,
          dirname: require('path').resolve(sails.config.appPath, 'uploads/'),
          saveAs: `YOUR_FILE_NAME.jpg`
        },
        function (err, files) {
          if (err) {
            console.log('Error: ' + err.message);
            return next(err);
          }

          if (files.length > 0) {
            var uploadedFile = files[0];
            var fileName = uploadedFile.filename;
            var sizeInBytes = uploadedFile.size;
            var path = uploadedFile.fd;

            
         
            req.body.fileName = fileName;
            req.body.sizeInBytes = sizeInBytes;
            req.body.filePath = path;
            req.body.imageName = name;
          
          }

          return next();
        }
      );
    } else {
      return next();
    }
  };
})(),

This blog has has a good example of handling a file upload--it worked for me:

http://maangalabs.com/blog/2014/08/12/uploading-a-file-in-sails/

upload: function  (req, res) {

    // Call to /upload via GET is error
    if(req.method === 'GET')
          return res.json({'status':'GET not allowed'});                        

    var uploadFile = req.file('uploadFile');
    console.log(uploadFile);

    uploadFile.upload(function onUploadComplete(err, files) {

        // Files will be uploaded to .tmp/uploads

        // IF ERROR Return and send 500 error with error
        if (err) return res.serverError(err);                               

        console.log(files);
        res.json({status:200,file:files});
    });
}

This will get you most of the way there: https://github.com/balderdashy/sails/issues/27

You can use https://github.com/aconbere/node-file-utils to create directories, etc. Install it with

npm install file

Require file in the module having code similar to that in .../sails/issue/27.
