redux-url

Build Status npm module

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
