Maintain browser's URI in state based on redux

Prerequisites

• Knowledge of redux-actions and -reducers
• thunk-middleware is applied to redux-store

Features

• Supports arbitrary sliceKey (default is "uri")
• Supports base-path, initialized by a carrier on import of reducer
• Updates state, if browser-uri changes
• Offers action to update browser's URI and/or query params
• Offers param "replace", if true history's "replaceState" is used.
• Adds origin if needed for location.href

Example

State

{
 	uri:{
		basePath:'/todolist'
		subPath:'/items',
		query:{
			id: 1
		}
	}
}

app's main

import {createStore, combineReducers, applyMiddleware} from 'redux'
import thunkMiddleware from 'redux-thunk'
import uri, {listenUri, init} from '@pubcore/redux-browser-history'

// optional, required if key is not 'uri' and not on first level of state
// init({sliceKey:'ui.uri'})

var {dispatch, getState} = createStore(combineReducers({
	uri
}), {}, applyMiddleware(thunkMiddleware))

//watch changes of browser's uri
listenUri(dispatch)

action to navigate between app's screens

import {updateUriAction} from '@pubcore/redux-browser-history'

export default navigate = page => dispatch => {
	dispatch(updateUriAction({subPath: '/' + page}))
	//...
}

update some query params

import get from 'lodash.get'
import {updateUriAction} from '@pubcore/redux-browser-history'
//[...]

const current = get(getState(), 'uri.query')
//[...]

//updateUriAction's query param must be "complete" => ther 's no merge
updateUriAction({ query:{...current, id: 3} })

// to remove all query params
// updateUriAction({ query:{} })

// to remove some query params, use "undefined"
// updateUriAction({ query:{..current, foo: undefined, bar: undefined} })

// to use history's replaceState (instead of pushState)
// updateUriAction({ query:{}, replace:true})
