I'm trying to download a photo through a URL passed as a query string using Express, but every time I try to use it, I get Error: Invalid URI "favicon.ico" Is there a way I can get my browser to stop requesting a favicon? For downloading images, I'm using the image-downloader package (NPM page)

Code:

app.get('/:url', (req, res) => {

let url = req.params.url;

const options = {

    url: url,

    dest: /path'

};

download.image(options)

    .then(({ filename, image }) => {

        console.log('File saved to ', filename);

})

    .catch((err) => {

        console.log(err);

    });

res.send("Done");

});

It's probably easiest to just make a route for favicon.ico in your server.

app.get('/favico.ico', (req, res) => {

    res.sendStatus(404);

});

Of course, you could actually send a valid icon too if you wanted, but this will at least keep your Express server from showing an error.

FYI, this has nothing to do with the image-downloader. This has to do with the browser requesting a favico.ico icon that it uses to show in the URL bar (and some other places in the browser UI). If your server returns a 404 for favicon.ico, the browser will use a generic icon in its UI.

If you want to make yourself a simple favico.ico, you can go here and it will help you generate one and then you can change the above route to:

app.get('/favico.ico', (req, res) => {

    res.sendFile("myfavico.ico");

});

Try using another package like request module. I believe it got this type of things handled.

var fs = require('fs'),

request = require('request');



var download = function(uri, filename, callback){

  request.head(uri, function(err, res, body){

    console.log('content-type:', res.headers['content-type']);

    console.log('content-length:', res.headers['content-length']);



    request(uri).pipe(fs.createWriteStream(filename)).on('close', callback);

  });

};



download('https://www.google.com/images/srpr/logo3w.png', 'google.png', function(){

  console.log('done');

});
