@craftercms/redux

@craftercms/redux

This package contains tools for integrating your application with Crafter Engine and Crafter Search using Redux as the state container.

Usage

All of Crafter CMS packages can be used either via npm or in plain html/javascript via regular script imports.

• Install module using yarn or npm
  • Yarn: yarn add @craftercms/redux
  • npm: npm install @craftercms/redux
• Set the Crafter Configuration (site, baseUrl).
• Import and use the redux store provided by the library, or implement your own store.
• Import and use the action(s) you need.

The examples below assume usage in the style of using via npm. If you're using the bundles, directly importing as a script in the browser, these functions will be under the global variable named craftercms.redux (i.e. window.craftercms.redux).

  const store = createReduxStore({
    namespaceCrafterState: true,   // Set to true to namespace craftercms states
    namespace: "craftercms",       // Namespace label used for craftercms states
    reducerMixin: allReducers,     // Your reducers (to combine them with the redux store)
