The docs are not there yet, but they will be added before the final release. For now, [this commit](https://github.com/gaearon/redux-devtools/commit/64f58b7010a1b2a71ad16716eb37ac1031f93915) is a good reference.\n\n# babel-plugin-react-transform\n\n[![react-transform channel on discord](https://img.shields.io/badge/discord-react--transform%40reactiflux-61DAFB.svg?style=flat-square)](http://www.reactiflux.com)\n\n:rocket: **Now with [Babel 6](https://github.com/babel/babel) support** (thank you [@thejameskyle](https://github.com/thejameskyle)!)\n\nThis plugin wraps React components with arbitrary transforms. In other words, **it allows you to instrument React components** in any way—limited only by your imagination.\n\n## 🚧🚧🚧🚧🚧\n\nThis is **highly experimental tech**. If you’re enthusiastic about hot reloading, by all means, give it a try, but don’t bet your project on it. Either of the technologies it relies upon may change drastically or get deprecated any day. You’ve been warned 😉 .\n\n**This technology exists to prototype next-generation React developer experience**. Please don’t use it blindly if you don’t know the underlying technologies well. Otherwise you are likely to get disillusioned with JavaScript tooling.\n\n**No effort went into making this user-friendly yet. The goal is to eventually kill this technology** in favor of less hacky technologies baked into React. These projects are not long term.\n\n## Table of Contents\n\n* [Ecosystem](#ecosystem)\n* [Demo Project](#demo-project)\n* [Installation](#installation)\n* [Writing Transforms](#writing-transforms)\n\n## Ecosystem\n\nFor a reference implementation, see [**react-transform-boilerplate**](https://github.com/gaearon/react-transform-boilerplate). \nFor a starter kit to help write your own transforms, see [**react-transform-noop**](https://github.com/pwmckenna/react-transform-noop).\n\n\n#### Transforms\n\n* [**react-transform-hmr**](https://github.com/gaearon/react-transform-hmr) - enables hot reloading using HMR API\n* [**react-transform-catch-errors**](https://github.com/gaearon/react-transform-catch-errors) - catches errors inside `render()`\n* [**react-transform-debug-inspector**](https://github.com/alexkuz/react-transform-debug-inspector) - renders an inline prop inspector\n* [**react-transform-render-visualizer**](https://github.com/spredfast/react-transform-render-visualizer) - highlight components when updated\n* [**react-transform-style**](https://github.com/pwmckenna/react-transform-style) - support `style` and `className` styling for all components\n* [**react-transform-log-render**](https://github.com/rkit/react-transform-log-render) - log component renders with passed props and state\n* [**react-transform-count-renders**](https://github.com/stipsan/react-transform-count-renders) - counts how many times your components render\n\nFeeling inspired?

These instructions assume you have a working project set up. If you do not have Babel set up in your project, [learn how to integrate](https://babeljs.io/docs/setup/) it with your toolkit before installing this plugin.\n\n##### Using NPM\n\nInstall plugin and save in `devDependencies`:\n\n```bash\nnpm install --save-dev babel-plugin-react-transform\n```\n\nInstall some transforms:\n\n```bash\nnpm install --save-dev react-transform-hmr\nnpm install --save-dev react-transform-catch-errors\n```\n\n##### Configuration\nAdd react-transform to the list of plugins in your babel configuration (usually `.babelrc`):\n\n```js\n\n\n{\n \"presets\": [\"react\", \"es2015\"],\n \"env\": {\n // this plugin will be included only in development mode, e.g.\n // if NODE_ENV (or BABEL_ENV) environment variable is not set\n // or is equal to \"development\"\n \"development\": {\n \"plugins\": [\n // must be an array with options object as second item\n [\"react-transform\", {\n // must be an array of objects\n \"transforms\": [{\n // can be an NPM module name or a local path\n \"transform\": \"react-transform-hmr\",\n // see transform docs for \"imports\" and \"locals\" dependencies\n \"imports\": [\"react\"],\n \"locals\": [\"module\"]\n }, {\n // you can have many transforms, not just one\n \"transform\": \"react-transform-catch-errors\",\n \"imports\": [\"react\", \"redbox-react\"]\n }, {\n // can be an NPM module name or a local path\n \"transform\": \"./src/my-custom-transform\"\n }]\n // by default we only look for `React.createClass` (and ES6 classes)\n // but you can tell the plugin to look for different component factories:\n // factoryMethods: [\"React.createClass\", \"createClass\"]\n }]\n ]\n }\n }\n}\n```\n\nAs you can see, each transform, apart from the `transform` field where you write it name, also has `imports` and `locals` fields. You should consult the docs of each individual transform to learn which `imports` and `locals` it might need, and how it uses them. You probably already guessed that this is just a way to inject local variables (like `module`) or dependencies (like `react`) into the transforms that need them.\n\nNote that when using `React.createClass()` and allowing `babel` to extract the `displayName` property you must ensure that [babel-plugin-react-display-name](https://github.com/babel/babel/tree/master/packages/babel-plugin-transform-react-display-name) is included before `react-transform`. See [this github issue](https://github.com/gaearon/babel-plugin-react-transform/issues/19) for more details.\n\nYou may optionally specify an array of strings called `factoryMethods` if you want the plugin to look for components created with a factory method other than `React.createClass`. Note that you don’t have to do anything special to look for ES6 components—`factoryMethods` is only relevant if you use factory methods akin to `React.createClass`.\n\n## Writing Transforms\n\nIt’s not hard to write a custom transform! First, make sure you call your NPM package `react-transform-*` so we have uniform naming across the transforms. The only thing you should export from your transform module is a function.\n\n```js\nexport default function myTransform() {\n // ¯\\_(ツ)_/¯\n}\n```\n\nThis function should *return another function*:\n\n```js\nexport default function myTransform() {\n return function wrap(ReactClass) {\n // ¯\\_(ツ)_/¯\n return ReactClass;\n }\n}\n```\n\nAs you can see, you’ll receive `ReactClass` as a parameter. It’s up to you to do something with it: monkeypatch its methods, create another component with the same prototype and a few different methods, wrap it into a higher-order component, etc. Be creative!\n\n```js\nexport default function logAllUpdates() {\n return function wrap(ReactClass) {\n const displayName = // ¯\\_(ツ)_/¯\n const originalComponentDidUpdate = ReactClass.prototype.componentDidUpdate;\n\n ReactClass.prototype.componentDidUpdate = function componentDidUpdate() {\n console.info(`${displayName} updated:`, this.props, this.state);\n\n if (originalComponentDidUpdate) {\n originalComponentDidUpdate.apply(this, arguments);\n }\n }\n\n return ReactClass;\n }\n}\n```\n\nOh, how do I get `displayName`?\nActually, we give your transformation function a single argument called `options`. Yes, `options`:\n\n```js\nexport default function logAllUpdates(options) {\n```\n\nIt contains some useful data. For example, your `options` could look like this:\n\n```js\n{\n // the file being processed\n filename: '/Users/dan/p/my-projects/src/App.js',\n // remember that \"imports\" .babelrc option?\n imports: [React],\n // remember that \"locals\" .babelrc option?\n locals: [module],\n // all components declared in the current file\n components: {\n $_MyComponent: {\n // with their displayName when available\n displayName: 'MyComponent'\n },\n $_SomeOtherComponent: {\n displayName: 'SomeOtherComponent',\n // and telling whether they are defined inside a function\n isInFunction: true\n }\n }\n}\n```\n\nOf course, you might not want to use *all* options, but isn’t it nice to know that you have access to them in the top scope—which means before the component definitions actually run? (Hint: a hot reloading plugin might use this to decide whether a module is worthy of reloading, even if it contains an error and no React components have yet been wrapped because of it.)\n\nSo, to retrieve the `displayName` (or `isInFunction`, when available), use the `options` parameter *and* the second `uniqueId` parameter given to the inner function after `ReactClass`:\n\n```js\nexport default function logAllUpdates(options) {\n return function wrap(ReactClass, uniqueId) {\n const displayName = options.components[uniqueId].displayName || '';\n```\n\nThis is it!\n\nSure, it’s a slightly contrived example, as you can grab `ReactClass.displayName` just fine, but it illustrates a point: you have information about all of the components inside a file before that file executes, which is *very* handy for some transformations.\n\nHere is the complete code for this example transformation function:\n\n```js\nexport default function logAllUpdates(options) {\n return function wrap(ReactClass, uniqueId) {\n const displayName = options.components[uniqueId].displayName || '';\n const originalComponentDidUpdate = ReactClass.prototype.componentDidUpdate;\n\n ReactClass.prototype.componentDidUpdate = function componentDidUpdate() {\n console.info(`${displayName} updated:`, this.props, this.state);\n\n if (originalComponentDidUpdate) {\n originalComponentDidUpdate.apply(this, arguments);\n }\n }\n\n return ReactClass;\n }\n}\n```\n\nNow go ahead and write your own! Don’t forget to tag it with `react-transform` [keyword on npm](https://www.npmjs.com/browse/keyword/react-transform).\n\n## Patrons\n\nThe work on React Transform, [React Hot Loader](https://github.com/gaearon/react-hot-loader), [Redux](https://github.com/rackt/redux), and related projects was [funded by the community](https://www.patreon.com/reactdx).
