Vue.js is the front-end JavaScript Framework to build tools and libraries.

The Axios works well in the platform like node.js and browsers. Vue.js Axios is a leading framework to Consume REST APIs is easy with them. Here all the example code is executed in Visual Studio Code with Node.js.

Creating the Vue Front-End

The Structure is given as :. Using Simple GET request. Vue lacks a built-in HTTP library, so Axios library is recommended to keep interaction with REST API.

So here in this article, we have used JSON PLACEHOLDER API to take a few sample data for the application.

Secondly, to perform Vue.js Component.

Lastly, add API to the vue.js Component. To handle errors in the Axios library ‘catch’ method is preferred as we use this in case of any network failure while requesting data.

Vue and Axios GET Example

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

POST request using axios with set HTTP headers

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.

Introduction to Vue.js Axios

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.

You may also have a look at the following articles to learn more –. Below is a quick set of examples to show how to send HTTP GET requests from Vue to a backend API using the axios HTTP client which is available on npm. Other HTTP examples available:.

Vue + Axios: POST. Vue + Fetch: GET, POST. React + Fetch: GET, POST, PUT, DELETE. React + Axios: GET, POST, PUT, DELETE.

Wrapping Up

Fetch: GET, POST, PUT, DELETE. With the npm CLI: npm install axios. With the yarn CLI: yarn add axios.

This sends an HTTP GET request from Vue to the npm api to search for all vue packages using the query q=vue, then assigns the total returned in the response to the component data property totalVuePackages so it can be displayed in the component template.

Example Vue component at https://codesandbox.io/s/vue-axios-http-get-request-examples-ei7l8?file=/app/GetRequest.vue.

This sends the same GET request from Vue using axios, but this version uses an async function and the await javascript expression to wait for the promises to return (instead of using the promise then() method as above).

Example Vue component at https://codesandbox.io/s/vue-axios-http-get-request-examples-ei7l8?file=/app/GetRequestAsyncAwait.vue.

This sends a GET request from Vue to an invalid url on the npm api then assigns the error message to the errorMessage component data property and logs the error to the console. Example Vue component at https://codesandbox.io/s/vue-axios-http-get-request-examples-ei7l8?file=/app/GetRequestErrorHandling.vue. This sends the same GET request again from Vue using axios with the HTTP Content-Type header set to application/json.
