This app provides monitoring and information features for the common freifunk user and the technical stuff of a freifunk community.
Code base is taken from a TUM Practical Course project and added here to see if Freifunk Altdorf can use it.

/** |
|
* Deferred provides a Promise-like API that exposes methods to resolve and |
|
* reject the Promise. It is most useful when converting non-Promise code to use |
|
* Promises. |
|
* |
|
* If you want to export the Promise without exposing access to the resolve and |
|
* reject methods, you should export `getPromise` which returns a Promise with |
|
* the same semantics excluding those methods. |
