Node Express custom 404 page

I have a pretty standard Node Express app with a global 404 handler like.

app.get('*', function(req, res){
    res.status(404);
    res.render('404page');
});

Now in some routes I have code like

app.get('/store/:product', function (req, res) {
  if (productNotFound) return res.sendStatus(404);
});

What I would like is the res.sendStatus(404) to redirect to the error page WITHOUT having to change it to res.sendStatus(404).render('404page').

Is that possible?

Just override .sendStatus of res object.

Register this middleware right after creating the express app:

app.use((req, res, next) => {
  const sendStatus = res.sendStatus.bind(res);
  res.sendStatus = (status) => {
    if (status === 404) {
      return res.status(404).render('404page');
    }
    return sendStatus(status);
  }
  next()
});
