redux-url

A redux middleware for synchronizing the url with your redux store's state. It provides a set of action creators for changing the url, and if the url matches a user-defined route, an action will be dispatched with some metadata of the url such as parameters and query.

It works with redux 3.x, 4.x

Install

npm install --save redux-url

Usage

import { createBrowserHistory as createHistory } from 'history'; // choose a history implementation
import { createStore, applyMiddleware } from 'redux';
import { createRouter, navigate } from 'redux-url';

const routes = {
    '/': 'HOME', // when url is matched, will dispatch an action of type 'HOME', the payload contains matched params and query
    '/todos/:id': ({ id }, query) => ({ type: 'CHANGE_TODO', payload: id, query }), // you can also pass a function to transform the action, the matched params, query and the original path will be passed in
    '*': 'NOT_FOUND'
};

const router = createRouter(routes, createHistory());
const store = createStore(
    reducer,
    applyMiddleware(router)
);

router.sync(); // In order to restore the state from the URL when refreshed

store.dispatch(navigate('/todos/123')); // navigate to '/todos/123'

API

• createRouter(routes, history):

  creates the middleware

  • arguments

    • routes (object) : The URL patterns to be mapped, where values can be either of the following:

      • string:

        when the URL matches the route, an action will be dispatched of which the type is the given string, and the payload has the following shape:

        {
          type: string,
          payload: {
            params: Object,
            query: Object,
            path: string
          }
        }

      • function: (object, object, string) => Action

        a function that takes the matched params, query and the original path, returns an action

    • history: the history object created from lib history, such as createBrowserHistory

  • returns

    the middleware which provides the following methods:

    • sync():

    synchronize the current url with the state, this is useful for handling the situation when the page is refreshed

• navigate(path: string, replace: boolean = false):

  creates an action for navigating to the path, replace indicates whether it should modify the current history entry rather than push a new one

• push(path: string):

  a shorthand of navigate(path, false)

• replace(path, string):

  a shorthand of navigate(path, true)

• goBack():

  creates an action for going back

• goForward():

  creates an action for going forward

• go(n: number):

  creates an action for going n (can be negative) steps
