Tutorial

Step 1

  1. Install locally package flux and events

  2. Every state change will be done using dispatching actions. So we need something to dispatch these actions - so let’s create AppDispatcher in src/AppDispatcher.js See the docs.

  3. Let’s start from fluxifing toggling basic info from enroll view (src/components/enroll/BasicInfo). We want to change toggleForm to not use setState but to dispatch action.

  4. Modification of the global state should happen in the store (although you can have more than one store), so let’s create store in src/stores/EnrollStore.js. Use register Dispatcher method to register for actions and handle TOGGLE_BASIC_INFO actionType.

  5. From events docs, use on, emit and removeListener for:

  • emitting change after handled TOGGLE_BASIC_INFO action in EnrollStore
  • subscribing to store change in component’s componentWillMount method
  • removing this subscription in componentWillUnmount method

The best for now would be to wrap event operations with methods in EnrollStore (we will move it out to more general place later).

  1. In the subscribed method in the component we can now finally update our local component state:
setState({ open: value })

where value should be taken from the store (you need to add proper method)

Step 2

Refactor code:

  1. create new folder - action_creators - and new class there - EnrollActionCreator.js
  2. move dispatching action to separate method in EnrollActionCreator
  3. create new folder - constants - and new file there - ActionTypes.js
  4. move TOGGLE_BASIC_INFO string there

Step 3

Do the same for toggleForm in src/enroll/Preferences.js

Step 4

Fluxify src/containers/Participants.js (there is setState in componentWillMount)

Step 5

Open page source and see that we don’t have any content there : ( Notice that <div id=“app”></div> where our app should be rendered is empty. It works perfectly client side, but it’s not server side, so our SEO sucks : (

Let’s take first step to make it make it better.

  1. We need to enable ES6 in server.js file, so let’s add --require babel-core/register to the dev script in package.json

  2. Open server.js and change it to use ES6 (imports, vars to consts, etc). References: Babel or E6-features.

Step 6

  1. Take a look on server side rendering doc of react-router library and try to use it in server.js

IMPORTANT TIPS not mentioned there:

  • you need to change routes.js to include only Route elements, you need to move Router element to the upper level (application.js).
  • you need to move creating history to the application.js
