LAB | Vue.js WikiCountries

Introduction

After spending too much time on GitHub, you found a JSON dataset of countries and you decided to use it to create your Wikipedia of countries!

Example - Finished LAB

Setup

  • Fork this repo

  • Clone this repo

  • Open the LAB and start:

    $ cd lab-vue-wiki-countries
$ yarn install
$ yarn start

Submission

  • Upon completion, run the following commands:

    git add .
git commit -m "done"
git push origin main

  • Create a Pull Request so that your TAs can check your work.

Getting Started

Clean the App.vue component so that it has the following structure inside the template tags

<!-- src/App.js -->
<template>
  <div class="app">
  </div>
</template>

Instructions

Iteration 0 | vue Router installation

Remember to install the vue Router:

$ yarn install vue-router

And set up the router in your src/router.js file:

// src/router.js
import { createRouter, createWebHistory } from 'vue-router';

const routes = [
  {
    path: '/',
    name: 'root',
    component: () => import(/* webpackChunkName: 'index' */ './pages/index.vue')
  },
  {
    path: '/list',
    name: 'list',
    component: () => import(/* webpackChunkName: 'list' */ './pages/CountriesList.vue')
    children: [
      {
        path: '/details',
        name: 'details',
        component: () => import(/* webpackChunkName: 'details' */ './pages/CountriesDetails.vue')
      },
    ]
  }
];

const router = createRouter({
  history: createWebHistory('/'),
  routes,
  scrollBehavior() {
    document.getElementById('app').scrollIntoView();
  }
});

Bootstrap installation

We will use Bootstrap V4 for the design 👍

$ yarn install bootstrap

To make the Bootstrap styles available in the entire app, import the stylesheet in index.js:

// src/main.js

import 'bootstrap/dist/css/bootstrap.css';

Instructions

Iteration 1.1 | Create components

In this iteration, we will focus on the general layout. Before you start, inside the src folder, create the components folder. There you will create at least 3 components:

  • Navbar: Displaying the basic navbar with the LAB name

  • CountriesList: Displays the list of links with the country names. Each link should be a vue-router-dom router-link which we will use to send the country code (alpha3Code) via the URL.

  • CountryDetails: Is the component that we will render via the vue-router's Route and will be receiving the country code (alpha3Code) via the URL.

    This is actually the id of the country (example: /ESP for Spain, /FRA for France).

To help you with the structure of the components, we gave you an example of a page inside example.html.

If you want to style it, refresh your memory on Bootstrap in the docs or check out how we approached styling in the example.html.

Iteration 1.2 | Navbar component

The simplest way to define a component in vue is to write a JavaScript function aka function component. The navbar should be displaying the title LAB - WikiCountries.

Iteration 1.3 | CountriesList component

This component should render a list of router-links that are used to trigger the browser URL change. Click on a router-link component will activate the corresponding Route showing the country details component.

Iteration 1.4 | CountryDetails component and router-view setup

Now that our list of countries is ready, we should create the CountryDetails page. CountryDetails displays the country details as per the link that we clicked. This component should be dynamically displayed/rendered with the <router-vue />.

<!-- Example -->

<router-view>

Components rendered with Vue.js can read the query with this.$route. We can use this to obtain the information coming from the browser's URL bar, for example, the alpha3Code code of the country.

NOTE: For the small picture of the flag, you can use the lowercased alpha2Code and embed it in the URL as shown below:

Iteration 2 | Linking it all together

Once done creating the components, the structure of elements that your App.js will render should look somewhat like this:

<div class="app">
  <Navbar />

  <div className="container">
    <div className="row">
      <CountriesList :countries="countries" />
      <router-view>
    </div>
  </div>
</div>

Iteration 3 | Set the state when the component mounts

Our App.vue application should pull countries into the vue data method, holding the data coming from the src/countries.json file.

Iteration 4 | Bonus | Fetch countries data from an API

Instead of relying on the static data coming from a json file, let's do something more interesting and get out the data from an actual API.

Let's make a GET request to the URL https://ih-countries-api.herokuapp.com/countries and use the data returned from the response as the list of the countries. You can use either fetch or axios to make the request.

You should use the mounted() Hook to set the lifcycle hook that runs only once and makes a request to the API. The request should happen first thing when the application loads, therefore think about when and from where we should make the request to the API.

Iteration 5 | Bonus | Fetch one country data from an API

Using the mounted() hook set CountriesDetails component. It should make a request to the RestCountries API and fetch the data for the specific country. You can construct the request endpoint using the country's alpha3Code. Example:

The effect should run after the initial render and each time the URL parameter with the alpha3Code changes.


Happy coding! ❤️
