nion is a library that makes it easy to fetch, update, and manage API data in a Redux store as well as bind it to React components. Nion strives to make working with data as flexible, consistent, and predictable as possible. 💖

nion is heavily inspired by Apollo and GraphQL.

nion is used as a hook which is given a declaration of what data is needed by the component that calls it.

import { useNion } from '@nion/nion'

export const UserContainer = () => {
    const [currentUser, actions, request] = useNion({
        dataKey: 'currentUser',
        endpoint: 'https://patreon.com/api/current_user',
    })

    const loadButton = <Button onClick={() => actions.get()}>Load</Button>

    return (
        <Card>
            {request.isLoading ? <LoadingSpinner /> : loadButton}
            {currentUser && <UserCard user={currentUser} />}
        </Card>
    )
}

We simply pass in a declaration object that tells nion what to fetch, and nion automatically handles fetching the data and returning it along with the corresponding request status.

nion can also be used as a decorator function which declares what data will be managed by the decorated component and passes in props for managing that data. This is a deprecated usage; we don't recommend writing new code that uses the decorator form.

nion requires redux-thunk in order to handle its async actions, so you should install that along with the nion package.

npm install nion redux-thunk --save

Since nion can be used as a decorator function, you might want to make sure you've got babel configured to handle decorator transpilation:

npm install babel-plugin-transform-decorators-legacy --save-dev

Finally, nion has to be wired up to the redux store and optionally configured. Here's a very simple setup:

import { applyMiddleware, createStore, combineReducers } from 'redux'
import thunkMiddleware from 'redux-thunk'

import { configureNion } from 'nion'

export default function configureStore() {
    const configurationOptions = {}
    const { reducer: nionReducer } = configureNion(configurationOptions)

    const reducers = combineReducers({
        nion: nionReducer,
    })

    let store = createStore(reducers, applyMiddleware(thunkMiddleware))

    return store
}
