sails.js: download file in assets directory

Question

I create a .xls file in assets/xls directory :

fs.writeFileSync('./assets/xls/data.xls', xls, 'binary');

And I want to download this file :

To get the file url :

var downloadLink = req.headers.host+'/xls/data.xls';

I do not understant why I have a 404 error on this url :
localhost:1337/xls/data.xls

Sorry it's present under your project folder or under your web deploy folder .tmp/public/xls/ ? Cause if it's only under your project folder it's normal to have 404 — jaumard, Apr 01 '15 at 13:55
I restart my server several times. I think it's a bug because after 10 tries my files is finallly in .temp directory. — damien marchand, Apr 01 '15 at 14:06
I think you have to do fs.writeFileSync(sails.config.appPath + "/public/xls/data.xls", xls, 'binary'); to write it directly under temp folder — jaumard, Apr 01 '15 at 14:32
yes, files are not loaded directly from assets, they are loaded from the tmp folder — Travis Webb, Apr 01 '15 at 21:58

This isn't the recommended practice for storing generated or user-uploaded files. The assets folder is only intended for your site's front-end assets.

If you want to provide download links in your app, you're encouraged to save them in a separate location and add a controller action that streams the requested file to the client. This allows you to add policies to protect those files, and avoids issues source control and with Grunt. See How do I authenticate access to assets folder in sails.js for an example of such a controller action.
