You can learn more about the comparison between the two styles and the potential benefits of Composition API in the Composition API FAQ. In return, its flexibility enables more powerful patterns for organizing and reusing logic. It is more free-form and requires an understanding of how reactivity works in Vue to be used effectively. The Composition API is centered around declaring reactive state variables directly in a function scope and composing state from multiple functions together to handle complexity.

It is also more beginner-friendly by abstracting away the reactivity details and enforcing code organization via option groups. The Options API is centered around the concept of a "component instance" ( this as seen in the example), which typically aligns better with a class-based mental model for users coming from OOP language backgrounds. In fact, the Options API is implemented on top of the Composition API! The fundamental concepts and knowledge about Vue are shared across the two styles. They are different interfaces powered by the exact same underlying system. Try it in the Playground Which to Choose? īoth API styles are fully capable of covering common use cases. Here's the previous example, written in SFC format: A Vue SFC, as the name suggests, encapsulates the component's logic (JavaScript), template (HTML), and styles (CSS) in a single file. In most build-tool-enabled Vue projects, we author Vue components using an HTML-like file format called Single-File Component (also known as *.vue files, abbreviated as SFC). This is why we call Vue "The Progressive Framework": it's a framework that can grow with you and adapt to your needs. If you are a veteran, you can pick the optimal way to leverage Vue based on the problems you are trying to solve, while retaining the same productivity. Even if you are just a beginner now, the knowledge gained along the way will stay useful as you grow to tackle more ambitious goals in the future.

If you are an experienced developer interested in how to best integrate Vue into your stack, or you are curious about what these terms mean, we discuss them in more detail in Ways of Using Vue.ĭespite the flexibility, the core knowledge about how Vue works is shared across all these use cases. If you find these concepts intimidating, don't worry! The tutorial and guide only require basic HTML and JavaScript knowledge, and you should be able to follow along without being an expert in any of these. Targeting desktop, mobile, WebGL, and even the terminal.Jamstack / Static Site Generation (SSG).Fullstack / Server-Side Rendering (SSR).Embedding as Web Components on any page.Enhancing static HTML without a build step.
Depending on your use case, Vue can be used in different ways: With that in mind, Vue is designed to be flexible and incrementally adoptable. But the web is extremely diverse - the things we build on the web may vary drastically in form and scale. Vue is a framework and ecosystem that covers most of the common features needed in frontend development. Prior experience with other frameworks helps, but is not required. If you are totally new to frontend development, it might not be the best idea to jump right into a framework as your first step - grasp the basics and then come back! You can check your knowledge level with this JavaScript overview.
The rest of the documentation assumes basic familiarity with HTML, CSS, and JavaScript.
