Alpine.js: Displaying API data in a HTML table

Last modified August 12th 2021 | GitHub Source Code [GitHub] | #alpine

In this tutorial we’ll be using Alpine.js to load data from an API and then display that data in a HTML table. We’ll be using the free SportsDB API to load a list of teams from the English Premier League along with some associated team data.

Let’s get started, for the purposes of this tutorial you can load Alpine via CDN:

<script defer src="https://unpkg.com/alpinejs@3.x.x/dist/cdn.min.js"></script>Code language: HTML, XML (xml)

Now for the HTML markup starting with a wrapper <div> for the component:

    x-data="{teams: [], 'isLoading': true}"
    .then(response => response.json())
    .then(response => { teams = response.teams; isLoading = false; console.log(response.teams); })"
<!-- Table will go here -->
</div>Code language: HTML, XML (xml)

x-cloak hides an element until Alpine has fully loaded, in this instance it will prevent the flash of the table header before the x-show has evaluated and hidden the element. Fo the x-cloak attribute to work you must also include the following CSS:

[x-cloak] {
  display: none !important;
}Code language: CSS (css)

x-data defines a chunk of HTML as an Alpine component and provides the reactive data for that component to reference. In this case it’ll store the team data in an array and the loading state of the component.

x-init is used to fetch the data and store it in x-data before processing and rendering the component. The data itself is being fetched with the JavaScript fetch() method using the SportsDB API endpoint for the English Premiere League teams.

If successful you should the team data logged in the browser console as follows:

Console log Alpine.js API data

We can now output this data into a HTML table:

<h1 x-show="isLoading">Loading...</h1>
<table x-show="!isLoading">
    <template x-for="team in teams" :key="team.idTeam">
        <td x-text="team.strTeam"></td>
        <td x-text="team.intFormedYear"></td>
        <td x-text="team.strStadium"></td>
        <td x-text="team.intStadiumCapacity"></td>
</table>Code language: HTML, XML (xml)

x-show toggles the visibility of the <h1> loading text and the <table> based on the value of isLoading. We then use the x-for directive to loop through each team and output that data using x-text into the individual table rows. The <template> element used here is a mechanism for holding HTML that is not to be rendered immediately when a page is loaded.

That’s all for this tutorial, in it we used 6 of the 15 directives available in V3 of Alpine.js. If your interested in exploring the framework further be sure to checkout some of our other Alipine.js tutorials.
