I made this because I wanted to use Redux to drive some of my complicated-document views implemented with the abstract-state-router.

Using it in theory

You initialize it with a state router and optional middlewares. It doesn't list any version of Redux in the package.json - it will use whatever version you add as a dependency to your project.

On any of your state, you can specify an optional initial state, reducer function, and even a function to run after the reducer step where you make any other side effects happen that you need to.

Ractive

This module is made to work with RactiveJS, but as you can see from the implementation, the coupling is very light. I would like to make it nonexistent in the future if possible.

If you are using the abstract-state-router with a different templating system and want to use Redux, fork this module - if your DOM library uses something instead of on to catch events, you'll need to make that change, otherwise the only thing you may need to change is the set method that takes the state object and applies it to the DOM object.

If you are using Ractive, just make sure to set twoway: false to disable two-way binding.

Using it in practice

npm install state-router-redux-ractive

Initialization requires only calling the function and passing in a state router:

``js
var Ractive = require('ractive')
var ractiveRenderer = require('ractive-state-router')
var StateRouter = require('abstract-state-router')
var routerRedux = require('state-router-redux-ractive')

var renderer = ractiveRenderer(Ractive)
var stateRouter = StateRouter(, 'body')

routerRedux(stateRouter)
`

You can associate a reducer function with any of your states by adding a reducer property to the data property of any state. Any state with a reducer can have also have an initialState, and/or an afterAction property.

`js
stateRouter.addState({
name: 'app.topics',
route: '/topics',
template: {
template: require('fs').readFileSync('implementations/ractive-redux/app/topics/topics.html', { encoding: 'utf8' }),
twoway: false
},
resolve: function(data, parameters, cb) {
all({
topics: model.getTopics,
tasks: model.getTasks
}, cb)
},
data: {
initialState: {
tasksUndone: {},
addingTopic: false
},
reducer: reducer,
afterAction: switchForNamedArgs({
START_ADDING_TOPIC: ({ domApi: ractive }) => ractive.find('.new-topic-name').focus(),
ADD_TOPIC: ({ state, dispatch }) => state.topics.forEach(
topicId => recalculateTasksLeftToDoInTopic(topicId, dispatch))
})
}
}
`

To see a "real-life" example, check out this demo state in the state-router-example.

The properties of data that are used:

- initialState: whatever you want Redux to be initialized with. Any properties returned by the resolve function will be applied to the initial state, overwriting any duplicate properties.
- reducer: any regular Redux reducer function. Will be passed straight to Redux.
- afterAction: called immediately after the reducers changes are applied to the store (synchronously). Passed these arguments:
- state - the store's new value after the reducer call
- dispatch - the dispatch function of the store
- domApi - the active DOM API of the state. A Ractive instance, in my case.
- action - the action object that caused the whole kerfuffle

How to dispatch actions?

These examples are Ractive, but whatever mechanism your DOM library uses for emitting events will work here. Dispatch actions from your Ractive template like so:

`html

Restore

`

To emit an action with the current contents of an input element, you can emit the dispatchInput event:

`html

`

The second event argument must be the DOM element object itself. The library will grab the value off of it for you (using dom-value) and put that value on the payload property of the action sent to the reducer.

Those are the only two events handled at the moment. I'm not sure if any more will be necessary/handy - we'll see!

Develop/test

`sh
git clone https://github.com/TehShrike/state-router-redux-ractive.git
cd state-router-redux-ractive
npm install
npm test
``

Suggestions welcome.

Since this project is the glue between three sizeable libraries, I don't want to load it down with a bunch of features, but I would love to talk over any ways it could be simplified, or changed to better suit its purpose.
