express middleware functions invoked twice when request is made from browser

    console.log(\"In intercept         


        

Answer 1

Found that it is happening due to /favicon.ico request made by browser. Adding specific handler (shown below) prevented default handler from being called twice

app.use('/favicon.ico', (req, res, next) => {
    console.log('favicon handler');
    res.sendStatus(200);
});
