Usage

Client

In your client entry point, call the render function from react-cornerstone passing in a function to configureStore, a function to createRoutes, a DOM element designating the mount point of the app, and any helpers to be made available to the redux-connect asyncConnect decorator. The created store will be returned if you need to use it further in your client setup (for example, you may want your incoming web socket events to dispatch actions).

import {render} from 'react-cornerstone';
 
const {store} = render(configureStore, createRoutesConfig, Component, document.getElementById('app'), helpers)

configureStore and createRoutesConfig are expected to be universal functions returning both the redux store and the routes config, respectively. More information on these can be found under the common section below.

The Component is the main bootstrap/app component rendered which will need to, amongst other app-specific things, render the correct component when a new location is reduced.

Hot Module Replacement

render also returns a function called reload which can be used to swap out the top level Component passed to it when the file has changed. See the react-hot-loader docs for more information on how to set this up correctly.

import Component from './path/to/Component';
 
const {reload} = render(configureStore, createRoutesConfig, Component, document.getElementById('app'))
 
if (module.hot) module.hot.accept('./path/to/Component', reload);

Server

In your server entry point, call the configureMiddleware function from react-cornerstone passing in the same configureStore and createRoutes functions as used in the client configuration, a template function for displaying the HTML including the mount point DOM element, and, optionally an object with the following configuration functions:

  • getInitialState(req) - Receives the Express request object and should return the initial state to be passed to the configureStore function. Useful if you need to, for example, add the authenticated user to the initial state.

  • getHelpers(req) - Also receives the Express request object and should return an object containing any helpers to be made available to the redux-connect asyncConnect decorator.

The server-side configureMiddleware function will return an Express middleware that uses react-route's match function to work out the active <Route/> and, with the corresponding components, redux-connect's loadOnServer is used to load any asynchronous data to initiate the redux store with.

import {configureMiddleware} from 'react-cornerstone';
 
const middleware = configureMiddleware(configureStore, createRoutesConfig, Component, template, {getInitialState, getHelpers})

The template function will be passed the output of react-dom/server's renderToString as the first parameter and the initial state as second. It is expected to at least return the page HTML including the mount point and the initial state javascript in a variable called window.__INITIAL_STATE__ along with the client-side code bundle. For example:

function template(componentHtml, initialState) {
  return `
    <!doctype html>
    <html>
    <body>
      <div id="mount">${componentHtml}</div>
      <script>
        window.__INITIAL_STATE__ = ${JSON.stringify(initialState)};
      </script>
      <script src="/client.js"></script>
    </body>
    </html>
  `
}

Common

configureStore(forClient, {map, ...options}, history, initialState = {})

  • forClient - a boolean to distinguish between client and server contexts. Obviously on the client-side this will be true and on the server, false.
  • {map, [...options]} - the route config to be passed to redux-first-router. The map will be the routes supplied to connectRoutes and any further properties will be passed along as the options parameter (see connectRoutes documentation).
  • history - the history strategy used by react-router. On the client-side this will be browserHistory and on the server, memoryHistory.
  • initialState - the initial state to seed the redux store with. On the client-side this will be the contents of window.__INITIAL_STATE__ and on the server, either an empty object or the result of calling getInitialState if passed to the server-side configureMiddleware function.

It is expected to return the store created by a call to redux's createStore. An opinionated implementation can be created by using the configureStoreCreator(reducers, [middleware]) function from react-cornerstone. Simply pass in your reducers and, optionally, an array of middleware:

import {configureStoreCreator} from 'react-cornerstone';
 
const configureStore = configureStoreCreator(reducers);

The configured store will include a reducer and middleware from react-router-redux to keep react-router and redux in sync, along with a reducer from redux-connect to track asynchronous data loading. Dev Tools Extension support will also be included if forClient is true.

Note: if a custom middleware stack is not provided via the optional middleware parameter, redux-thunk is included by default to handle asynchronous actions.

createRoutes(store)

  • store - the redux store. On both the client and server, this will be the store created by calling configureStore as defined above. This can be useful if you need to check some store property and react to it in a route's onEnter event handler.

The return value should be the <Route/> configuration to be utilised by react-router.
