Create a component & fetch GitHub user details with Vue.js & Semantic UI πŸ‘©β€πŸ’»

In this tutorial, you'll learn how to make a Vue component using the bare minimum requirements. What we are building is a GitHub user card which has the following content:

  • The profile picture.
  • GitHub profile name.
  • Joining date.
  • User bio.
  • The number of followers.

All in all, it will look something like this:

Semantic UI Card

If you're familiar with Semantic UI, this is exactly what it's card component is like.

You'll get to know how to fetch data from the GitHub API endpoint and how to connect it with the Vue instance.

Let's jump straight in!

Is this a jump or a facepalm?

Prerequisites πŸ™ƒ

Attention to extreme new-comers in web development! This tutorial is for those who have worked on:


Write the HTML markup 😌

Inside the index.html file, you need to have the root app element div which will help Vue to mount it on the webpage.

Before we move any further, add the following Semantic UI CSS CDN:

https://cdnjs.cloudflare.com/ajax/libs/semantic-ui/2.4.1/semantic.min.css

Next, we copy the card component markup code listed here.

<div id="app">
    <!-- Template from Semntic UI docs -->
    <div class="ui card">
      <div class="image">
        <img src="https://semantic-ui.com/images/avatar2/large/kristy.png">
      </div>
      <div class="content">
        <a class="header">Kristy</a>
        <div class="meta">
          <span class="date">Joined in 2013</span>
        </div>
        <div class="description">
          Kristy is an art director living in New York.
        </div>
      </div>
      <div class="extra content">
        <a>
          <i class="user icon"></i>
          22 Friends
        </a>
      </div>
    </div>
  </div>

As you can see, under the ui card class, we have an image which holds the default avatar. After this, we have a content block that holds all the details like the header, metadata, the description and finally the extra content which contains number of friends.

Write the Vue! 😎

Just before the closing </body> tag, add the Vue.js CDN script:

<script src="https://unpkg.com/vue"></script>

Make a new main.js file under the same project folder, link it with your HTML, and then create the Vue instance.

Code the component

Create the new component template at the top of the body. This is where the card will render:

<github-card username="username"></github-user-card>

The next step is to register our component. We use Vue.component method. Let's give it a name github-card. We need a single prop, username which is of type: String and is made required by default as we need it to hit the GitHub API endpoint.

Our user details will be stored in the data() property. Next, we need to have a method to call the GitHub API, so we will use the much popular Axios library to fetch the details. Make sure you grab its CDN by including the following script:

https://unpkg.com/axios/dist/axios.min.js

Now, this AJAX call will be done in two places:

  • First, once the component is created.
  • Second, before it's mounted to the document.

Checkout this lifecycle diagram for better context.

So, inside the created hook, we use the get() method to pass the API URL. i.e. https://api.github.com/users/${this.username}. The response data is set to the user property.

Here's the code:

Vue.component('github-card', {
      props: {
        username: {
          type: String,
          required: true
        }
      },
      data() {
        return {
          user: {}
        };
      },
      async created() {
        const response = await axios.get(`https://api.github.com/users/${this.username}`);
        this.user = response.data;
      }
    });

    new Vue({
      el: '#app',
    });

Create the template

We use the X-Template method to put the above HTML syntax. But first, we give it a suitable id of github-card-template making sure we also update the Vue code by adding the template with this id. Cut all the Semantic UI HTML and add it under the new X-Template script.

The GitHub API format and all the data which we can get is available on their website in the JSON format.

Let's replace the hardcoded values with the newly accessible user object from the API. Here are the replacements:

  • <img src="https://semantic-ui.com/images/avatar2/large/kristy.png"> -> <img :src="user.avatar_url">
  • "Kristy" -> {{ user.name }}
  • "Joined in 2013" -> Joined in {{ user.created_at }}
  • "Kristy is an art director living in New York." -> {{ user.bio }}
  • "22 Friends" -> {{ user.followers }} Followers

Remember that we're using the moustache format for the JavaScript code.

Here's the new code:

<script type="text/x-template" id="github-card-template">
    <div class="ui card">
      <div class="image">
        <img :src="user.avatar_url">
      </div>
      <div class="content">
        <a :href="`https://github.com/${username}`" class="header">{{user.name}}</a>
        <div class="meta">
          <span class="date">Joined in {{user.created_at}}</span>
        </div>
        <div class="description">
          {{user.bio}}
        </div>
      </div>
      <div class="extra content">
        <a :href="`https://github.com/${username}?tab=followers`">
          <i class="user icon"></i>
          {{user.followers}} Followers
        </a>
      </div>
    </div>
  </script>

As you can see, I've added links in between the name and the follower count using the :href argument.

Refresh the browser page and there you have it! You've just created a GitHub component in Vue and styled it with Storybook. How cool!

Where to next? πŸ€”

  • Make these cards for multiple users!
  • Use GitHub data to get more info
  • Use Semantic UI's other components to display the data.

Thanks for reading, I appreciate it! Have a good day. (βœΏβ—•β€Ώβ—•βœΏ)
