[Redux] Navigating with React Router <Link>

We will learn how to change the address bar using a component from React Router.

 

In Root.js:

We need to add a param to change the Route:

import React from 'react';
import {Provider} from 'react-redux';
import {Router, Route, browserHistory } from 'react-router';
import App from './App';

const Root = ({ store }) => (
    <Provider store={store}>
        <Router history={browserHistory}>
            <Route path="/(:filter)" component={App}/>
        </Router>
    </Provider>
)

export default Root;

(:filter) means: it might not exisits.

 

In Foot.js, displaying the filter link like this;

const Footer = () => (
  <p>
    Show:
    {" "}
    <FilterLink filter="SHOW_ALL">
      All
    </FilterLink>
    {", "}
    <FilterLink filter="SHOW_ACTIVE">
      Active
    </FilterLink>
    {", "}
    <FilterLink filter="SHOW_COMPLETED">
      Completed
    </FilterLink>
  </p>
);

 

We want to change it little bit, so it would be more url friendly:

  <p>
    Show:
    {" "}
    <FilterLink filter="all">
      All
    </FilterLink>
    {", "}
    <FilterLink filter="active">
      Active
    </FilterLink>
    {", "}
    <FilterLink filter="completed">
      Completed
    </FilterLink>
  </p>

 

In the FilterLink.js: 

We rewrite the code by using <Link> from 'react-router':

import React from 'react';
import { Link } from 'react-router';

const FilterLink = ( {filter, children} ) => (
    <Link
      to={filter === 'all' ? '' : filter}
      activeStyle={{
        textDecoration: 'none',
        color: black
      }}
    >
      {children}
      </Link>
);

export default FilterLink;

If the filter is 'all', then just use default url.

If the link is actived, then use the activeStyle.

 

And we can delete the action creator for setVisibilityFilter in actions.js:

//delete

export const setVisibilityFilter = (filter) => ({
    type: 'SET_VISIBILITY_FILTER',
    filter,
});

 

Aslo delete the Link.js, it is not needed anymore, we use the Link component from react-router.
