I have a server on express.js and there is a static folder in its root directory, it contains several react apps, something like this:

app:
    static:
           react1
           react2

I am trying to make sure that when accessing the /react1 and /react2 addresses, the express will display the required application.

app.js:

app.use (express.static(path.join(__ dirname, "static")));
app.use ("/", indexRouter);

index.router:

router.get('/react1', (req, res) => {
  res.sendFile(path.join (__dirname, '..', 'static', 'react1', 'index.html'))
});

router.get('/react2', (req, res) => {
  res.sendFile(path.join (__dirname, '..', 'static', 'react2', 'index.html'))
});

When I try to navigate through these handles, I get a blank page. What am I doing wrong?
