By: Heitor Ramon Ribeiro

Overview of this book

Vue.js is a progressive web framework for building professional user interfaces for your web applications. With Vue.js 3, the frontend framework is reinforced with architectural enhancements, new base languages, new render processes, and separated core components. The book starts with recipes for implementing Vue.js 3’s new features in your web development projects and migrating your existing Vue.js apps to the latest version. You will get up and running with TypeScript with Vue.js and find succinct solutions to common challenges and pitfalls faced in implementing components, derivatives, and animation, through to building plugins, adding state management, routing, and developing complete single-page applications (SPAs). As you advance, you'll discover recipes to help you integrate Vue.js apps with Nuxt.js in order to add server-side rendering capabilities to your SPAs. You'll then learn about the Vue.js ecosystem by exploring modern frameworks such as Quasar, Nuxt.js, Vuex, and Vuetify in your web projects. Finally, the book provides you with solutions for packaging and deploying your Vue.js apps. By the end of this Vue.js book, you'll be able to identify and solve challenges faced in building Vue.js applications and be able to adopt the Vue.js framework for frontend web projects of any scale.

Fetching Data from the Web via HTTP Requests

Data is a part of everyday life nowadays. If it weren't for data, you wouldn't be reading this book or trying to learn more about Vue.

Knowing how to fetch and send your data inside an application is a requirement for a developer, not just an extra skill that's nice to have. The best way to learn it is by practicing it and finding out how it is done behind the scenes.

In this chapter, we will learn how to build our own API data manipulation with the Fetch API and the most popular API library in the web right now, axios.

In this chapter, we'll cover the following recipes:

Creating a wrapper for the Fetch API as an HTTP client
Creating a random cat image or GIF component
Creating your local fake JSON API server with MirageJS
Using axios as the new HTTP client
Creating different axios instances
Creating a request and...
