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.

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

const Memory = require("ninja-util/memory");

checkMemory([log])

NOTE: Node only

Logs the memory from the node application

Example:

memory.checkMemory("now")

Posibble Output:

now 5.5186767578125

compreensiveBytes(bytesCount)

Example

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
