Vue.js is a component-based declarative framework for building user interfaces built on top of HTML, CSS nad JavaScript.
Single-File Components
Most vue projects use components built with HTML-like files called Single-File Components (SFC) with the *.vue extension. Those files encapsulate components logic, template, and styles in one file, and they are a defining feature of the framework
API Options
Vue components can use one of two API styles: Options API and Composition API.
Options API is centred around a “component instance”, abstracting away the reactivity details and enforcing more organisation via option groups.
Composition API is focused on declaring reactive state variables. It’s doesn’t impose limitations, but requires more understanding about reactivity and the framework, offering flexibility and reusable logic in return.
On the Vue.js website the authors recommend going with Options for low-complexity scenarios and Composition for full Applications (in production use)
