# Implement a Root-Level Request Logger Middleware
|
|

## Problem Explanation
|
|
|
|
It is easier to write this challenge all at the top (there is already a stub for it). This is because middleware must be placed the function calls you want it to be used for.

## Hints
|
|
|
|
### Hint 1
|
|
|
|
To set up your own middleware you can do it like so:
|
|
|
|
```javascript
|
|
app.use(function middleware(req, res, next) {
|
|
// Do something
|
|
// Call the next function in line:
|
|
next();
|
|
});
|
|
```
|
|
|
|
If you have trouble formatting the string correctly, one way to do it looks like:
|
|
|
|
```javascript
|
|
var string = req.method + " " + req.path + " - " + req.ip;
|
|
```
