Worldwide Routing

This exercise has you building an experience to navigate continents and their countries. We'll use React Router to create the links and pages and manage browser history.

Setup

After cloning this repo:

cd worldwide-routing
npm install
npm run dev

Set up HashRouter in your client/index.js.

  • Import the router from 'react-router-dom' at the top of the file. i.e. import { HashRouter as Router } from 'react-router-dom'

  • Inside your ReactDOM.render() function, wrap the <App /> component in <Router></Router> tags.

Note: You could place the router within the App instead, around specific components, but by wrapping it around App we will give everything access to the Router's functionality.

Release 1

Let's start with the couple of components that make up the home page. Check out the App.jsx component. It currently contains the main header as shown in the following image, the instructions are in a Home component, and the beginnings of the Nav component are also in place.

  • Start by completing the Nav component so that it contains a list of continent names (like in the image below) based on the information from data/continents. Add a list item for Home too.

Tip: You can use Object.keys() on what is exported from data/continents.js to get a list of continent names.

  • Import and then use the Route component from react-router-dom so that the Nav component will show on all pages, but the Home component will only show on '/'.

Release 2

Next, add a route for /continents/:name to your App.jsx. We will use it to show the selected continent and its respective image from data/continents.js file.

  • Create a Continent component for this route. It should use params to determine which continent to show.

  • Use the Link component from react-router-dom in your Nav to create links for the user to the correct continent.

  • In the Continent component, also show a list of countries that the given continent contains.

Notice how Continent has replaced the Home component in the image below.

Release 3

In this release, we'll create a component for an individual country. This is the first time you'll need to use data/countries.js.

  • Create a route for this page. It should look something like: /continent/:name/:code.

Note: We're using the continent name and country code for this route to help us later. The url path for the above suggestion will be entered into the browser as /continent/Oceania/NZ

  • This route should render a Country component that shows all the information (in data/countries) about that specific country.

  • Make sure the country list in Continent can link to the page you've just created (remember that Link component).

Release 4

Currently each country just shows a string of it's neighbours' country codes. Create a list that will show each neighbour's name instead and be a link to that country's page so you can visit the pages of neighbours easily.

Future Releases

Here are some ideas for future releases:

  • If you haven't already, add a Home link in the Nav component.

  • Bold the selected continent in the Nav when viewing a continent or country and/or change the bullet point style (as shown in the release 4 screenshot) so users will know where they are.

  • Countries currently show up in the order decided by the data files. Add a feature to show them alphabetically or perhaps even by population.

  • Think about a different way you could navigate around this data and implement it in a different branch.
