## react-native-debug-stylesheet



When you want to debug layout problems, use this instead of the normal

`StyleSheet` to get coloured borders (or backgrounds) around views that

are affected by the stylesheet.



![Demo](https://raw.githubusercontent.com/brentvatne/react-native-debug-stylesheet/master/demo.png)



## Add it to your project



1. Run `npm install react-native-debug-stylesheet --save`

2. When you want to debug a layout problem, do something like this:



```javascript

var { PixelRatio, StyleSheet } = require('react-native');

// Drop this in to override the above StyleSheet var and use the

// DebugStyleSheet class instead.

var StyleSheet = require('react-native-debug-stylesheet');



// Business as usual

StyleSheet.create({

  // ....

});

```



If you prefer to use coloured backgrounds, then do this:



```javascript

var StyleSheet = require('react-native-debug-stylesheet').Backgrounds;

```



### Customize



If you'd rather make your own debug stylesheet than use the default

border/background color options, you can do this easily too.



```javascript

var { createDebugStylesheet, randomHexColor } = require('react-native-debug-stylesheet');



var doubleHeaderFontSize = function(styleClass, cssProperty, cssValue) {

  if (cssValue && styleClass.match(/header/)) {

    return cssValue * 2;

  }

  return cssValue;

}



var StyleSheet = createDebugStylesheet({

  backgroundColor: randomHexColor, fontSize: doubleHeaderFontSize,

  borderColor: randomHexColor, borderWidth: 0.5,

});

```
