React-native-power-logger

A react-native specific debugging tools, a lightweight customizable logger to log regular items, the react-native bridge, async storage and array's maps

Example:

console.pl.logStorage(); // See in table format all your react-native async storage

Installation

$ npm install react-native-power-logger

Then, in index.js or at top of your application:

const RNlog = require('react-native-power-logger');
'...or'
import RNlog from 'react-native-power-logger';

console.pl = RNLog;

Usage

you can now use regular console around, and have a console.pl object that contains all the Power Logger methods!

So you can do:


console.pl.logBridge(); // this will log the bridge messages

Test on demo project

Install react-native cli
open path in terminal and run: react-native init demo && cd demo && npm install react-native-power-logger
import and place some code on top of test application to have insight of bridge `js import RNlog from 'react-native-power-logger'

RNlog.logBridge(); AppRegistry.registerComponent(appName, () => App);


## What can i do?
1. Log React-native bridge, filters can be applied to choose only one way of data flow, specific method or module name
2. Log React-native async storage, dumps all the data from async storage, displayed in table format
3. Log items with customizable prefix, break line, colors and level of importance
4. Log from already in place Array.prototype.map
5. Log from specific Array.prototype.logMap placed in code before being changed in favor of regular "map"

## API
`overrideArraysMap()`
```js

overrideArraysMap()

const testArray = [ "a","b","c" ];

testArray.map(item => item); // every cicle will log current item, index and total array

enableArraysLogMap()


enableArraysLogMap() //extend native with Array.prototype.logMap

const testArray = [ "a","b","c" ];

testArray.map(item => item); // this will remain a regular map
testArray.logMap(item => item); // every cicle will log current item, index and total array

logStorage()


logStorage() // returns a table in console with async storage data displayed

logBridge(versus, prefix)

[optional, string] versus: "toJavascript" || "toNative", [optional, string] prefix: "prefix-message"


logBridge() // returns in console a log of every data exchange in react-native bridge

findInBridge(targets, prefix)

[optional, string[]] targets: ["module name", "method name"], [optional, string] prefix: "prefix-message"


findInBridge() // returns in console a log of the items we need to look up in bridge

log(target, prefix, level, lineBreak, breakColor)

[optional, any ] target: objINeedToLog, [optional, string] prefix: "prefix-message", [optional, string] level: "info" || "warn" || "err", [optional, boolean] lineBreak: true, [optional, string] breakColor: "#fff"


log() // returns a customized console.log

info(target)


info() // returns a console.info

warn(target)


warn() // returns a console.warn

err(target)


err() // returns a console.err

trace()


trace() // returns a console.trace

Warnings

overrideNativeMap will override the native Array.prototype.map, use it only for debugging. When turned on will dump all items from all the array's maps (frameworks included).
