Sometimes, depends on where it is defined in the route chain.
Middleware is the code/application/module that communicates between two systems, such as between servers and databases. The code above is different than a route because it is always run whenever the application gets to these lines.

| * If morgan is signed in he or she will have dev environment variable. The body-parser appears to set the environment variable to json(). Meaning it's parsing all data to json. |

Morgan provides logs which are not very useful outside of development.
without body-parser we would lose access to req.body
| * **Question:** Try creating a new vegetable. Then, try restarting your server. What happens to the data you posted and why? | ||
|
|
||
| * **Your Answer:** | ||
| I was having issues with getting anything to post to state. But considering that it was a state if you refresh the server I would assume state would be saved. |

Since we never saved the data to a file or database it exists only as a javascript object which is lost when the server restarts.
