This differs significantly from typical Rails. When considering what goes into **react_on_rails**, we ask ourselves, is the functionality related to the intersection of using Rails and with modern JavaScript? If so, then the functionality belongs right here. In other cases, we're releasing separate npm packages or Ruby gems. If you are interested in implementing React using traditional Rails architecture, see [react-rails](https://github.com/reactjs/react-rails). React on Rails integrates Facebook's [React](https://github.com/facebook/react) front-end framework with Rails. React v0.14.x is supported, with server rendering. [Redux](https://github.com/reactjs/redux) and [React-Router](https://github.com/reactjs/react-redux) are supported as well, also with server rendering.

Each pull request shows a git "diff" that highlights the changes that the generator has made. Another good option is to create a simple test app per the [Tutorial](docs/tutorial.md). - -### Understanding the Organization of the Generated Client Code -The generated client code follows our organization scheme. Each unique set of functionality, is given its own folder inside of `client/app/bundles`. This encourages for modularity of *domains*. - -Inside of the generated "HelloWorld" domain you will find the following folders: - -+ `startup`: two types of files, one that return a container component and implement any code that differs between client and server code (if using server-rendering), and a `clientRegistration` file that exposes the aforementioned files (as well as a `serverRegistration` file if using server rendering). These registration files are what webpack is using as an entry point. -+ `containers`: "smart components" (components that have functionality and logic that is passed to child "dumb components"). -+ `components`: includes "dumb components", or components that simply render their properties and call functions given to them as properties by a parent component. Ultimately, at least one of these dumb components will have a parent container component. - -You may also notice the `app/lib` folder. This is for any code that is common between bundles and therefore needs to be shared (for example, middleware). - -### Redux -If you have used the `--redux` generator option, you will notice the familiar additional redux folders in addition to the aforementioned folders. The Hello World example has also been modified to use Redux. - -Note the organizational paradigm of "bundles". These are like application domains and are used for grouping your code into webpack bundles, in case you decide to create different bundles for deployment. This is also useful for separating out logical parts of your application. The concept is that each bundle will have it's own Redux store. If you have code that you want to reuse across bundles, including components and reducers, place them under `/client/app/lib`. - -### Using Images and Fonts -The generator has amended the folders created in `client/assets/` to Rails's asset path. We recommend that if you have any existing assets that you want to use with your client code, you should move them to these folders and use webpack as normal. This allows webpack's development server to have access to your assets, as it will not be able to see any assets in the default Rails directories which are above the `/client` directory. - -Alternatively, if you have many existing assets and don't wish to move them, you could consider creating symlinks from client/assets that point to your Rails assets folders inside of `app/assets/`. The assets there will then be visible to both Rails and webpack. - ## Multiple React Components on a Page with One Store You may wish to have 2 React components share the same the Redux store. For example, if your navbar is a React component, you may want it to use the same store as your component in the main area of the page. You may even want multiple React components in the main area, which allows for greater modularity. In addition, you may want this to work with Turbolinks to minimize reloading the JavaScript. A good example of this would be something like an a notifications counter in a header. As each notifications is read in the body of the page, you would like to update the header. If both the header and body share the same Redux store, then this is trivial. Otherwise, we have to rely on other solutions, such as the header polling the server to see how many unread notifications exist. Suppose the Redux store is called `appStore`, and you have 3 React components that each need to connect to a store: `NavbarApp`, `CommentsApp`, and `BlogsApp`. I named them with `App` to indicate that they are the registered components. You will need to make a function that can create the store you will be using for all components and register it via the `registerStore` method. Note, this is a **storeCreator**, meaning that it is a function that takes (props, location) and returns a store: -``` +```js function appStore(props, railsContext) { // Create a hydrated redux store, using props and the railsContext (object with // Rails contextual information). return myAppStore; } @@ -546,47 +405,17 @@ [React Router](https://github.com/reactjs/react-router) is supported, including server side rendering!
