+# React Hot Loader + Redux dev tool support
+
+React Hot loader allows us to introduce changes in the application
+source code meanwhile we are running our web server and get the changes into our page without having to reload the browser and not loosing the application
+state.
+
+Redux dev tool is a chrome add-on that allows us to browse the state, replay actions, inject actions, export / import state...
+
+# Steps to configure hot Loader
+
+You don't need to update the source code of the app, all we have to do is install a list of npm packages, add some babel configuration, and then set a web server + updates on the webpack.config.
+
+Packages to install (dev dependencies):
+
+ - react-hot-loader 
+
+```
+npm install react-hot-loader --save-dev
+```
+
+webpack config updates:
+
+```javascript
+//(...)
+module.exports = {
+
+  // TODO: remove hot loading entry points in production
+  entry: [
+    'webpack-dev-server/client?http://localhost:8080',
+    'webpack/hot/only-dev-server',
+    './index.tsx',
+    './css/site.css',
+    '../node_modules/toastr/build/toastr.css',
+    '../node_modules/bootstrap/dist/css/bootstrap.css'
+  ],
+
+  devServer: {
+      contentBase: './dist', //Content base
+      inline: true, //Enable watch and live reload
+      host: 'localhost',
+      port: 8080,
+      noInfo: true,
+      hot: true,
+      historyApiFallback: true
+  },
+
+
+  // (...)
+
+  module: {
+		loaders: [
+      {
+        test: /\.(ts|tsx)$/,
+        exclude: /node_modules/,
+        loaders: ['react-hot', 'ts']
+      },
+      // (..)
+	},
+
+  plugins:[
+    new webpack.HotModuleReplacementPlugin(),
+    new webpack.NoErrorsPlugin(),
+    // (...)
+  ]
+}
+```
+
+
+# Steps to configure Redux dev tool
+
+First we have to download the app from the chrome store.
+
+Then we have to add a line of code to the create store to check
+wether is enabled the dev tool (app.tsx).
+
+````javascript
+let store = createStore(
+  reducers,
+   compose(
+     applyMiddleware(ReduxThunk)
+     ,nonTypedWindow.devToolsExtension ? nonTypedWindow.devToolsExtension() : f => f
+   )
+);
+````

 ##Call for contributors:
 
 Some months ago this project started as something internal... let's create some simple samples that cover react / redux / typescript scenarios that could serve as a guidance and reference in the future... now, we and other developers are using this repo as quick by sample guidance. We keep on adding more samples to it, but we have found that older samples need some updates / refactoring.
