fast-redux - O(1) speed and dynamic importing of actions/reducers

Fully compatible with Redux but works with O(1) speed when Redux itself works with O(N) speed (N is number of reducers). You can use standard Redux devtools with fast-redux actions.

When you dispatch an action, Redux invokes all reducers and passes the state and the action to each reducer. Usually it's not a problem but in complex applications when you have hundreds of reducers and will dispatch an action for every

onChange
of an input field in a form, you may observe performance issues. fast-redux solves this problem by using actions bound directly to reducers. Using this approach, for every action is executed exactly one reducer and you don't need to use constants for action types to match actions with reducers. You may see such fast-redux actions using well-known Redux DevTools and use its time traveling capabilities. More about performance issues that fast-redux aims to solve.

Plays well with code splitting. You can dynamically import actions/reducers to the store during lifetime of the applications.

Don't repeat yourself. Constants for action types aren't need (say goodbye to

switch
statements as well).

Installation

To install the stable version:

npm install --save fast-redux

The Redux source code is written in ES2015 but we precompile both CommonJS and UMD builds to ES5 so they work in any modern browser.

You can use fast-redux together with React, or with any other view library.
It is tiny (1kB, including dependencies).

fast-redux is simpler and IMO better version of Edux (my first attempt to make Redux more developer friendly).

Example

// examples/async/src/stores/selectedReddit.js

import {namespaceConfig} from 'fast-redux'

const DEFAULT_STATE = 'reactjs' export const { action, getState: getSelectedReddit } = namespaceConfig('selectedReddit', DEFAULT_STATE)

export const selectReddit = action('selectReddit', (state, reddit) => reddit )

Please look at

directory for more complex use cases.

You can compare 2 versions of same application: Redux version and FastRedux version.

More examples of FastRedux stores you can find in microchain demo app.
