react-redux is a great module that allows us to decouple our components from our state, so we can focus only on the view. It does this by providing a connector that maps state and actions to props, effectively allowing us to make all our components dumb again (which is a good thing).

To use it you create a mapStateToProps function and a mapDispatchToProps function, which return state properties and actions respectively. The problem is you have to do this for every component which requires something from the state or performs an action, leading to a lot of repetition and boilerplate code.

simple-react-redux allows you to leverage the power of react-redux declaratively: instead of creating the required functions, you add props to your element to tell it what to get from the state and which actions to use.

Let's say you have a person component, which needs name and age from the state and dispatches the updateName action. With react-redux the code would look something like this:

import {connect} from 'react-redux';
import {updateName} from './actions';

var Person = React.createClass({

function mapStateToProps(state) {
    return {
        age: state.age

function mapDispatchToProps(dispatch) {
    return {
        updateName: function (newName) {
            return dispatch(updateName(newName));

export default connect(mapStateToProps, mapDispatchToProps)(Person);

Using simple-react-redux you can achieve the same functionality with just a few lines of code:

import simpleConnect from 'simple-react-redux';
import {updateName} from './actions';

var Person = React.createClass({
    // ...

export default simpleConnect(Person);

And then when you use it:

<Person getFromState={["name", "age"]} getFromActions={{updateName: updateName}} />

And that's it!
