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.

How it works...

In this recipe, first, we imported the exposed APIs - createApp, defineComponent, setup, ref, onMounted, and onUnmounted, – as constants, which we will use to create the component. Then, we created the fetchLocation function, which has the responsibility of getting the user's geolocation data and returning it as reactive data that can be automatically updated when the user changes their location.

The ability to fetch the user GPS positions was possible because of the navigator.geolocation API present on modern browsers, which are able to fetch the user's current GPS position. Using this data provided by the browser, we were able to use it to define the variables created with the Vue ref APIs.

We created the component using the setup function of the Vue object declaration, so the rendering knows that we are using the new composition API as the component creation method. Inside the setup function, we imported the dynamic variables of the fetchLocation function...
