+# Ninja-Util
+
+This library has a set of helper classes and functions that are shared by our application following common patterns that we use on them. We mostly use `MVC`, `SOLID` and `Observer Pattern`.
+
+
+## Callback
+
+Wraps a callback to be executed, check if it is a valid function and execute without exceptions.
+
+```js
+const {Callback} = require("ninja-util");
+Callback.invoke(aCallback); 
+```
+
+## Express Wrapper
+
+Wraps the http methods from the express and automatically set the  response based on the callback invoked by the application
+
+Examples:
+```
+
+const { ExpressWrapper } = require ('ninja-util');
+
+```
+
+## Heap
+
+> TODO
+
+## Logger
+
+Useful to logs the application to make easier to turn on and turn off logs.
+
+`TODO: document`
+## Memory
+
+
+```js
+const Memory = require("ninja-util/memory");
+```
+
+#### checkMemory([log]) 
+> NOTE: Node only
+
+Logs the memory from the node application
+
+Example:
+```js
+memory.checkMemory("now")
+```
+
+Posibble Output:
+```
+now 5.5186767578125
+```
+
+#### compreensiveBytes(bytesCount) 
+
+Example
+```js
+console.log(memory.compreensiveBytes(42))
+console.log(memory.compreensiveBytes(42000))
+console.log(memory.compreensiveBytes(42000000))
+```
+
+Output:
+```
+42b
+41.02kb
+40.05mb
+```
+
+#### getCurrentMemory([asNumber])
+
+Returns the current footprint from the node application. If `asNumber` is set true, it will return in a number as bytes. Otherwise, it will convert using the `compreensiveBytes`, default is false.
+
+Example:
+```
+ memory.getCurrentMemory()
+ memory.getCurrentMemory(true)
+```
+
+Possible Output:
+
+```
+5.84mb
+6244264
+```
+
+## Observer
