It’s the title.

Is it possible to put variables in routes in Express?

You need to elaborate further. Nobody can help you without assumptions unless you provide a proper description of the problem.

I guess you mean dynamic routes, so for instance, premake a /articles/{id}.
You can do that like so:

// Put the dynamic part after a colon (:).
app.get('/article/:id', function(req , res){
  res.render('article' + req.params.id);
  // Instead of .id put whatever you put in the dynamic part
});

Adding on to @Nicolello’s answer, if the route itself should be variable:

app.get(`/${variable}`, function(req, res) {
    res.render("some_secret_page.html");
})
