Kraken with Shopping Cart, universal react view rendering, and PayPal integration. Uses lokijs as an in-memory database. You can easily swap out for an external database, such as MongoDB.


  • You will need Node (Version >= 4 preferred)


Clone, install and run.

  • anemone-machina and for universal react view rendering
  • anemone-lingua for localized content (en-US or es-ES) from .properties files
  • react-router for URL/view mapping
  • flux to manage the application lifecycle and architecture
  • 'browserify` for browser JavaScript dependency management
  • bundalo for localized messages with model data
  • lokijs for storing product information
  • Integration with the PayPal SDK

React components

krakenjs (PayPal's JavaScript open source umbrella) has namespaced important react-related modules under the anemone namespace.


The example utilizes anemone-machina for rendering views on both the client and server (as an express view engine).

The express view engine is configured in config/config.json in this block:

    "express": {
        "view engine": "jsx",
        "view": "require:anemone-machina/lib/expressView",
        "view cache": false,
        "views": "path:./public/views"
    "view engines": {
        "jsx": {
            "module": "anemone-machina/lib/server",
            "renderer": {
                "method": "create",
                "arguments": [
                        "routes": "require:./routes.jsx",
                        "routesFilePath": "path:./routes.jsx"


Configured as a middleware in config/config.json:

        "reactContentLoader": {
            "priority": 100,
            "enabled": true,
            "module": {
                "name": "anemone-lingua",
                "arguments": [
                        "contentPath": "path:./locales",
                        "fallback": "en-US"


Please see routes.jsx for the Router definition. You can see server-rendered views by making a direct get request for any of:

  • /
  • /products
  • /cart

When the application is loaded in the browser, clicking any of the main navigation links will illustrate browser-rendered views.


The flux-based patterns can be found in the files under public/js/*.js. You can also see the flux listeners pushed down from the routes.jsx file.


  • The browserify bundle.js build is defined in Gruntfile.js as well as tasks/browserify.js.
  • The development hot-loader construx-browserify for the bundle is configured in config/development.json
  • The above block also specifies routes.jsx as this application makes use of react-router.
  • The browser react renderer is configured in public/main.js

PayPal SDK

config changes (config.json):

"paypalConfig": {
	"host": "",
	"port": "",
	"client_id": "EBWKjlELKMYqRNQ6sYvFo64FtaRLRR5BdHEESmha49TM",
	"client_secret": "EO422dn3gQLgDbuwqTjzrFgFtaRLRR5BdHEESmha49TM"


lib/spec.js configures the PayPal SDK upon startup


Payment initiated in the /pay route which is defined in controllers/pay/index.js

Localized content

config changes (config.json):

"i18n": {
	"contentPath": "path:./locales",
	"fallback": "en-US"

config changes (config.json) under middleware:

"locale": {
	"priority": 95,
	"enabled": true,
	"module": {
		"name": "path:./lib/locale"

locale is chosen via the /setLanguage/:locale route, which is initiated by hyperlinked flag images in the UI

locale is set into the response via the locale middleware defined in lib/locale.js

Localized model data with bundalo

bundalo is used to provide localized messages directly in server responses. The bundle middleware, lib/getBundle.js, attaches a bundle property to the response object.

bundle.get({'bundle': 'messages', 'locality': locality}, function bundleReturn(err, messages) {
		if (err) {
			console.error(err && err.stack || err);
			return next(err);
		res.bundle = intl(messages);

Note the line res.bundle = intl(messages);. intl is a local method (utilizing intl-messageformat) that adds an additional getter to the existing bundalo API. You can see that in use in controllers/index.js:

model.itemsInCart = res.bundle.getIntl('items', {cartItemLength: cartLength});
//combines the given model with the property from
//items=You have {cartItemLength} items in your cart.

This combines the property with the given model. intl-messageformat can transform the model data based on the user's locale if necessary.
