contentful-redux

This library provides an implementation of the Contentful sync API for redux and reselect. contentful-redux handles the complete synchronization workflow (including cyclic link resolution, localization, and incremental syncing) and lets you consume your contents from Contentful as easy-to-use selectors.

If you are not already familiar with redux (and reselect), you should familiarize yourself with those first before trying to integrate contentful-redux into your project.

Installation

contentful-redux is provided as a collection of CommonJS modules, which can be installed using npm:

npm install --save contententful@5 contentful-redux

or using yarn:

yarn add contentful@5 contentful-redux

Usage

1. Setup contentful-redux (contentful.js):

import { createClient } from 'contentful';
import contentfulRedux from 'contentfulRedux';
 
export const { actions, reducer, middleware, selectors } = contentfulRedux({
    createClient,
    space: 'YOUR_SPACE_ID',
    accessToken: 'YOUR_ACCESS_TOKEN',
    stateSelector: state => state.contentful
});

1. Include the contentful reducer in your reducer:

import { combineReducers } from 'redux';
import { reducer as contentful } from './contentful';
 
export const reducer = combineReducers({
    contentful,
    // your other reducers
});

1. Include the contentful middleware in your redux store configuration:

import { applyMiddleware, createStore } from 'redux';
import { middleware as contentful } from './contentful';
 
export const configureStore = () => {
    return createStore(reducer, null, applyMiddleware(contentful));
};

1. Derive your reselect selectors from the base selectors provided by contentful-redux:

import { createSelector } from 'reselect';
import { selectors } from './contentful';
 
export const myModelEntities = createSelector(
    selectors.entries, selectors.contentTypes,
    (entries, contentTypes) => entries.filter(each => each.__contentType__ === contentTypes.myModel)
);

1. Dispatch a sync action whenever you want:

import { actions } from './contentful';
dispatch(actions.sync());
