+# react-transform-catch-errors
+
+A [React Transform](https://github.com/gaearon/babel-plugin-react-transform) that catches errors inside `render()` function and renders a React component with an error message instead.
+
+It’s up to you to choose the React component to render an error message. For example, you may use [redbox-react](https://github.com/KeywordBrain/redbox-react) that imitates React Native “red screen of death”.
+
+## Installation
+
+First, install the [Babel plugin](https://raw.githubusercontent.com/gaearon/babel-plugin-react-transform):
+
+```
+npm install --save-dev babel-plugin-react-transform
+```
+
+Then, install the transform:
+
+```
+npm install --save-dev react-transform-catch-errors
+```
+
+Finally, install the component for rendering errors, for example:
+
+```js
+npm install --save-dev redbox-react
+```
+
+You may also use a custom component instead.
+
+Now edit your `.babelrc` to include `extra.babel-plugin-react-transform`.  
+It must be an array of the transforms you want to use:
+
+```js
+{
+  "stage": 0,
+  "plugins": [
+    "react-transform"
+  ],
+  "extra": {
+    // must be defined and be an array
+    "react-transform": [{
+      "target": "react-transform-catch-errors",
+      // now go the imports!
+      // the first import is your React distribution
+      // (if you use React Native, pass "react-native" instead)
+      // the second import is the React component to render error
+      // (it can be a local path too, like "./src/ErrorReporter")
+      "imports": ["react", "redbox-react"]
+    }]
+    // note: you can put more transforms into array
+    // this is just one of them!
+  }
+}
+```
+
+This transform has no effect when `process.env.NODE_ENV` is set to `'production'`.
