Download file by NodeJS and SailsJS

Question

I need to make an APIto download a static file test.js.

When I test the API with Postman the result is just display the content of file, not downloading.

Is that ok?

async downloadTemplate(req , res) {
    let fs = require('fs');
    if(fs.existsSync('downloads/test.js'))
    {   
        res.setHeader('Content-disposition', 'attachment; filename=' + 'test.js');

        let filestream = fs.createReadStream('downloads/test.js');
        //return res.download('downloads/test.js' , 'test.js')
        return filestream.pipe(res);
    } else {
        res.json({error : "File not Found"});
    }
}

Postman should not be used for downloading files.

The client that will consume the API should decide what to do with the result.

If the client is going to be a browser - just test the api with a browser, not with postman.

In case the link to the server is in html - use the download attribute in the href

In case you are using Axios you can find the help you need here

You don't need onClick, just put the link on the href : `` . Check this https://www.w3schools.com/tags/att_a_download.asp – yeya Jan 06 '19 at 12:42
