However, using jQuery just for making Ajax calls is not recommended.

  • You don’t want to include the whole jQuery library just for the purpose of using Ajax, do you?
  • For Vue.js, you have quite a few options for using Ajax, such as:.
  • Browser's built-in fetch API (Using fetch).
  • Here is an example of using the Browser's fetch API.

The syntax above is using the jQuery.ready shorthand to create the Vue only after the page is loaded. Without jQuery, you might want to listen for the DOMContentLoaded event.


Alternatively, just load the script that creates the Vue at the bottom of the page and not in the header. Here is a complete, working example.

The web is progressing fast with new technologies and libraries emerging every few months. Vue.js is one of the Javascript frameworks gaining immense popularity over the last few years.

Initially launched in 2014, it derives inspiration from Angular but is very lightweight and ideal for building single-page web applications.

  • In this blog post, we are going to take a dig at integrating public APIs with a simple Vue.js application to fetch and display data on UI.
  • In case you are wondering, here is an article on the concept of APIs that also covers the various types and categories of APIs supported by us at RapidAPI.
  • According to the official documentation, Vue is a progressive framework for building user interfaces.

It supports augmented rendering of the HTML markup through a template declaration bound to a data model.

When the data model is updated, the browser’s HTML DOM also changes accordingly.

Vuejs is a frontend-end framework, and hence it is implemented only in the view layer.

Using Axios to Fetch Remote Data

Evan You, a former Google and Meteor employee, created Vue.js.

He wanted to extract the good parts of Angular, such as data binding and the>A separate file ‘scripts.js’ defines the Vue.js component.

  • Create a new file named ‘scripts.js’ in the root directory and add the following code.
  • This is a barebones Vue.JS component definition with an Options object containing the ‘el’, ‘data’ , and ‘methods’ properties.

The ‘el’ property points to the “#main” selector which is the id of the top-level

element in the HTML.

Building News App Components

The ‘data’ contains three data variables that you will use later for displaying text returned from the API in the HTML.

The ‘methods’ property defines a single function fetchAPIData( ).

Acquire an API Key

This is currently left blank but will be defined in the subsequent steps.

  • With the ‘el’ bound to the CSS selector of the top-level
    element, this Vue.js component is attached to the
  • Create a new file named ‘styles.css’ in the root directory.

Leave the file empty for now.

Project Structure

We will come back to it later. You will now edit the ‘script.js’ file to add the API call to the Vue.js component. Before that, you must decide on the API.

The choice of API is dependent on the application that you are building, or the API functionality that you are relying upon to be fulfilled by the API. For this Vue.js example, we have chosen the Jokes Database API.

It returns a joke every time you call it and is very simple to use.

What is Vue.js?

The idea here is to have a simple web page that can display a joke every time the user clicks on a button.
