There is also a library called ‘vue-resource’ to do such things, but it’s said that it is not used well due to it’s slow update cycle and larger community of Axios. Enter the following command line to install Axios. Then add method in main.js so that Axios can be used globally. Using a service called JSONPlaceholder, I’ll test the Axios I just installed.

You can copy and paste following code. Basically, IE doesn’t support promise, so you may need polyfill of es6-promise to enable it. You can install it with command below. Next, just add one line below in your webpack config file.

Using the Loading indicator while the page takes too much time to the respond from the backend.

In this section, we shall see how to use Vue.js and Axios together. Showing Simple Request Page.

Next, this Java Script part shows application Logic. We have used mount () to the API to make a request, and the results are saved.

Creating Basic Vue Application by building an HTML Page by creating html in editor.

Fetching data from API’s through Vue.js Axios. Explanation: To do this, we have already created a project in Vue using Vue-CLI, and next is by installing the Axios library as shown in the above Screenshot.

So this example fetches data from the JSON API, which is created already, and we get that request by .get () in the code.

And now the output looks like this when you open a browser. Fetching data from the third party. Code: index.html. By now, we have understood the functionality of the application and the fundamentals. This article would be a pretty starting point to handle API calls in any application and helpful in future projects.

Therefore, we have achieved here how to send an HTTP request to the Node.js and fetches respective data from the database. This is a guide to Vue.js Axios. Here we discuss How Axios works in Vue.js and Examples along with the codes and outputs.

Introduction to Vue.js Axios

You may also have a look at the following articles to learn more –. A small wrapper for integrating axios to Vuejs. I created this library because, in the past, I needed a simple solution to migrate from vue-resource to axios.

It only binds axios to the vue instance so you don't have to import everytime you use axios. Import libraries in entry file:. Usage in Vue 2:. Usage in Vue 3:.

Just add 3 scripts in order: vue, axios and vue-axios to your document. This wrapper bind axios to Vue or this if you're using single file component. You can use axios like this:. This wrapper bind axios to app instance or this if you're using single file component. in option API, you can use axios like this:.

How to handle errors in Axios

however, in composition API setup we can't use this, you should use provide API to share the globally instance properties first, then use inject API to inject axios to setup:.

Base Example

Please kindly check full documentation of axios too. The library allows to have different version of axios at the same time as well as change the default registration names (e.g.

axios and $http). To use this feature you need to provide options like an object where:.

is registration name. is instance of axios. For Vue it looks like this:.

It works similarly in Options API of Vue 3 but if you want to use Composition API you should adjust your code a bit to extract proper keys, e.g.:.

You’re browsing the documentation for v2.x and earlier. For v3.x, click here. There are many times when building application for the web that you may want to consume and display data from an API. There are several ways to do so, but a very popular approach is to use axios, a promise-based HTTP client. In this exercise, we’ll use the CoinDesk API to walk through displaying Bitcoin prices, updated every minute.

First, we’d install axios with either npm/yarn or through a CDN link. There are a number of ways we can request information from the API, but it’s nice to first find out what the shape of the data looks like, in order to know what to display.

In order to do so, we’ll make a call to the API endpoint and output it so we can see it. We can see in the CoinDesk API documentation, that this call will be made to https://api.coindesk.com/v1/bpi/currentprice.json.

So first, we’ll create a data property that will eventually house our information, and we’ll retrieve the data and assign it using the mounted lifecycle hook:.

Lesson Project

And what we get is this:. See the Pen First Step Axios and Vue by Vue (@Vue) on CodePen. We’ve got some data. But it looks pretty messy right now so let’s display it properly and add some error handling in case things aren’t working as expected or it takes longer than we thought to get the information. It’s pretty typical that the information we’ll need is within the response, and we’ll have to traverse what we’ve just stored to access it properly.

Wrapping Up
