|  | 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. | ||
|  | 
 | ||
|  | 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; | ||
|  | ``` | ||
|  |
