Given an express server, what are the correct statements about it?

Question

Considering the following express server :

```javascript
const path       = require('path');
const express    = require('express');
const bodyParser = require('body-parser');

let app          = express();
let messages     = [];

app.use('/message', bodyParser.urlencoded({extended:true}));
app.use('/message/add', express.static(path.join(__dirname, 'messagesViews')));

app.post('/message/add', (req, res) => {
  let { username, message } = req.body;
  messages.push({ username, message });

res.send('Message posté !');
});

app.get('/message', (req, res) => {
  res.json(messages);
});

app.listen(1337);
```

What statement are true?

Accepted Answer

If we `GET/message/add`, the server will serve the `messagesViews/index.html` page.

Accepted Answer

During a `POST/message/add`, the parameters sent are placed in a new object, which is added to the global `messages` array.

Accepted Answer

If we `GET/message`, we get a JSON containing all the messages.

Answer

The `app.post('/message/add', …)` route can never be reached because the `express.static()` middleware is instantiated on the same route just before.
