Vue.js Single-File Components (SFC)

Naming Conventions: Assign a unique name attribute to all public components to facilitate identification and management via references in the code.
Logic Separation: Extract complex business logic into separate utility functions or mixins whenever possible to prevent &lt;script&gt; tags from becoming overly long and difficult to read.
Style Isolation: Always use the scoped modifier to limit the propagation scope of styles, preventing accidental impact on other page components.

In the Vue.js ecosystem, Single File Components (SFC) serve as the cornerstone for building maintainable and scalable frontend applications. They allow developers to encapsulate templates, logic, and styles within a single independent .vue file, significantly enhancing code organization and readability. This structure not only aligns with modern web development best practices but also forms the foundational configuration unit of mainstream toolchains like Vue CLI. Through SFC, teams can clearly delineate responsibility boundaries in large projects, achieving decoupling and reusability between components.
A standard .vue file typically consists of three main sections: Script, Template, and Style. These three parts work together to constitute the complete lifecycle of a Vue component.
