![]() ![]() This lets you use Vue as a drop-in replacement for a library like JQuery. In that function, we create data and state variables.Vue is a modern JavaScript framework that provides useful facilities for progressive enhancement - unlike many other frameworks, you can use Vue to enhance existing HTML. Technically, a composable is just a function we export ( useFetch() in our case). When I have some data, I put it in a data option when I have some functions, I put them in a methods option, and so on: Everything has its own place and I can just put it in there. It seemed to me way more clear and elegant in contrast to the Angular and React equivalents. When I found Vue for the first time, I was hooked by its Options (object-based) API. The motivation for the Composition API to be added to Vue 3 is clear and simple: producing more compact and defragmented code. Motivation to Add the Vue Composition API to the Framework It incorporates all of the three principles described above and allows for creating abstract, portable, and loosely coupled components that can be reused and shared between different projects. The Composition API is a new strategy for building and structuring Vue 3 components. Of course, complete decoupling is impossible - which is why the more accurate term used by developers is “loosely coupled”. They’re as independent of each other as possible. A piece of code is decoupled from another one when changing one doesn’t require changing the other. ![]() ![]() A piece of code is portable when it can be used not only in different places in one project but also in different projects. A piece of code is abstract when it can suit multiple different use cases (like classes in many programming languages). For me, there are three main principles of reusability: Let’s consider what makes a piece of code reusable. What Is Composition API and Why It Was Created As the Vue framework has evolved, it it has continued to offer much better reusability approaches. This applies equally to Vue as to other programming languages and frameworks. As time has passed, these strategies have been constantly polished and improved, and new ones are constantly developed. Since the earliest days of programming, the problem of code repetition has made programmers invent strategies for keeping their code DRY, reusable and portable. In this tutorial, we’ll explore how to use the Vue 3 Composition API and its latest code reusability capabilities.Ĭode sharing and reusability are one of the cornerstones of software development. ![]()
