redux-action-router

A super simple router middleware for redux that maps routes to actions or action creators.

How to use

Installation

npm install --save redux-action-router

Example usage

This will create a middleware that maps two hash based urls to actions.

import { createStore, applyMiddleware } from 'redux';
import createRouterMiddleware from 'redux-action-router';
import myRootReducer from './yourRootReducer.js';

let routesToActions = {
  '/thing/:id': 'selectThing'
}

let routerMiddleware = createRouterMiddleware(routesToActions);
let store = applyMiddleware(routerMiddleware)(createStore)(myRootReducer);

window.location.href = '#/thing/1?param=true';
//This will dispatch an action:
//{type:'selectThing', id:'1', param:'true' }

What it does

The simplest way to use this is as a mapping between url routes and redux action types.

{
  '/myRoute/:id' : 'showMyRoute',
  '/some/other/route/:param' : 'showSomeOtherRoute'
}

When used with a route description like the above, when the url changes to include #/myRoute/1, it will dispatch a redux action {type:'showMyRoute', id:'1'}.

This allows you to take routing information out of your React components and deal with all url changes as if they were just Redux actions.

Using with action creators

You can also use it with action creators to get more sophisticated with what happens when a route changes:

{
  '/foo': () => {type:'fooAction', key:'someValue'},
  '/route/:param1/:param2': ({param1, param2}) => dispatch =>
    dispatch({type:'someAction', subject:param1});
    dispatch({type:'anotherAction', subject:param2});
  }
}

In the above, we have a route #/foo that will use an action creator to dispatch an action with some hardcoded value, and a route #/route/:param1/:param2 that uses an action creator to dispatch a thunk that dispatches two separate actions, each with one of the params from the route. You can use this pattern with thunks to string together very complex orchestration logic that needs to occur on route change.

Changing the url by dispatching an action

When you use an action creator like in the above example, you may find yourself wanting to change the url. You can do this by dispatching an action of type urlChange with a property url to the route eg: {type:'urlChange', url:'/some/url'}.

Changes

• 0.2.0 Removes bi-directionality of route to url mapping. Previously, dispatching an action that was mapped to a route would automatically change the url. In practice, this has proved to be not very useful so it is being removed.
  Adds support for query parameters.

• 0.1.0 Adds support for dispatching action creators, urlChange actions.

Roadmap for 1.0

• Add support for pushState/popState/replaceState, right now only hash based urls work
