-## react-codemod
-
-This repository contains a collection of codemod scripts based for use with
-[JSCodeshift](https://github.com/facebook/jscodeshift) that help update React
-APIs.
-
-### Setup & Run
-
-  * `npm install -g jscodeshift`
-  * `git clone https://github.com/facebook/react.git` or download a zip file
-    from `https://github.com/facebook/react/archive/master.zip`
-  * `jscodeshift -t <codemod-script> <file>`
-  * Use the `-d` option for a dry-run and use `-p` to print the output
-    for comparison
-
-### Included Scripts
-
-`findDOMNode` updates `this.getDOMNode()` or `this.refs.foo.getDOMNode()`
-calls inside of `React.createClass` components to `React.findDOMNode(foo)`. Note
-that it will only look at code inside of `React.createClass` calls and only
-update calls on the component instance or its refs. You can use this script to
-update most calls to `getDOMNode` and then manually go through the remaining
-calls.
-
-  * `jscodeshift -t react/packages/react-codemod/transforms/findDOMNode.js <file>`
-
-`react-to-react-dom` updates code for the split of the `react` and `react-dom`
-packages (e.g., `React.render` to `ReactDOM.render`). It looks for
-`require('react')` and replaces the appropriate property accesses using
-`require('react-dom')`. It does not support ES6 modules or other non-CommonJS
-systems. We recommend performing the `findDOMNode` conversion first.
-
-  * `jscodeshift -t react/packages/react-codemod/transforms/react-to-react-dom.js <file>`
-  * After running the automated codemod, you may want to run a regex-based find-and-replace to remove extra whitespace between the added requires, such as `codemod.py -m -d src --extensions js '(var React\s*=\s*require\(.react.\);)\n\n(\s*var ReactDOM)' '\1\n\2'` using https://github.com/facebook/codemod.
-
-`pure-render-mixin` removes `PureRenderMixin` and inlines
-`shouldComponentUpdate` so that the ES2015 class transform can pick up the React
-component and turn it into an ES2015 class. NOTE: This currently only works if you
-are using the master version (>0.13.1) of React as it is using
-`React.addons.shallowCompare`
-
- * `jscodeshift -t react/packages/react-codemod/transforms/pure-render-mixin.js <file>`
- * If `--mixin-name=<name>` is specified it will look for the specified name
-   instead of `PureRenderMixin`. Note that it is not possible to use a
-   namespaced name for the mixin. `mixins: [React.addons.PureRenderMixin]` will
-   not currently work.
-
-`class` transforms `React.createClass` calls into ES2015 classes.
-
-  * `jscodeshift -t react/packages/react-codemod/transforms/class.js <file>`
-  * If `--no-super-class` is specified it will not extend
-    `React.Component` if `setState` and `forceUpdate` aren't being called in a
-    class. We do recommend always extending from `React.Component`, especially
-    if you are using or planning to use [Flow](http://flowtype.org/). Also make
-    sure you are not calling `setState` anywhere outside of your component.
-
-These three scripts take an option `--no-explicit-require` if you don't have a
-`require('React')` statement in your code files and if you access React as a
-global.
-
-### Explanation of the ES2015 class transform
-
-  * Ignore components with calls to deprecated APIs. This is very defensive, if
-    the script finds any identifiers called `isMounted`, `getDOMNode`,
-    `replaceProps`, `replaceState` or `setProps` it will skip the component.
-  * Replaces `var A = React.createClass(spec)` with
-    `class A (extends React.Component) {spec}`.
-  * Pulls out all statics defined on `statics` plus the few special cased
-    statics like `propTypes`, `childContextTypes`, `contextTypes` and
-    `displayName` and assigns them after the class is created.
-    `class A {}; A.foo = bar;`
-  * Takes `getDefaultProps` and inlines it as a static `defaultProps`.
-    If `getDefaultProps` is defined as a function with a single statement that
-    returns an object, it optimizes and transforms
-    `getDefaultProps() { return {foo: 'bar'}; }` into
-    `A.defaultProps = {foo: 'bar'};`. If `getDefaultProps` contains more than
-    one statement it will transform into a self-invoking function like this:
-    `A.defaultProps = function() {…}();`. Note that this means that the function
-    will be executed only a single time per app-lifetime. In practice this
-    hasn't caused any issues – `getDefaultProps` should not contain any
-    side-effects.
-  * Binds class methods to the instance if methods are referenced without being
-    called directly. It checks for `this.foo` but also traces variable
-    assignments like `var self = this; self.foo`. It does not bind functions
-    from the React API and ignores functions that are being called directly
-    (unless it is both called directly and passed around to somewhere else)
-  * Creates a constructor if necessary. This is necessary if either
-    `getInitialState` exists in the `React.createClass` spec OR if functions
-    need to be bound to the instance.
-  * When `--no-super-class` is passed it only optionally extends
-    `React.Component` when `setState` or `forceUpdate` are used within the
-    class.
-
-The constructor logic is as follows:
-  * Call `super(props, context)` if the base class needs to be extended.
-  * Bind all functions that are passed around,
-    like `this.foo = this.foo.bind(this)`
-  * Inline `getInitialState` (and remove `getInitialState` from the spec). It
-    also updates access of `this.props.foo` to `props.foo` and adds `props` as
-    argument to the constructor. This is necessary in the case when the base
-    class does not need to be extended where `this.props` will only be set by
-    React after the constructor has been run.
-  * Changes `return StateObject` from `getInitialState` to assign `this.state`
-    directly.
-
-### Recast Options
-
-Options to [recast](https://github.com/benjamn/recast)'s printer can be provided
-through the `printOptions` command line argument
-
- * `jscodeshift -t transform.js <file> --printOptions='{"quote":"double"}'`
