How to return a picture (stupid question)?

Question

JavaScript

I'm probably doing it very stupidly, but, having abandoned Apache, I began to transfer my assets using fs, with the following code:

app.get('/assets/css/index.css', function(req, res) {
    fs.readFile('/var/www/assets/css/index.css', function(err, data) {
        res.end(data);
    });
});

And so a question: I need to return the image to the user through res.end. This is how it doesn't work:

app.get('/sources/exit.svg', function(req, res) {
    fs.readFile('/var/www/sources/exit.svg', function(err, data) {
        res.end(data);
    });
});

Answer 1

Don't reinvent the wheel, use express.static()
And it doesn't work most likely because of the wrong (or even missing) Content-Type header
