Vue Local Components

Vue Local Components

They help keep your app clean, modular, and well-scoped.

 What are Local Components?

A local component is:

• Imported into a component

• Registered inside that component

• Available only there, not globally

 Scope:

 Why Use Local Components?

•  Better encapsulation
•  Avoids global namespace pollution
•  Improves maintainability
•  Ideal for feature-specific UI

 Basic Example

 Child Component (HelloBox.vue)

 Parent Component (App.vue)

• HelloBox is local to App.vue only

 Local Registration Syntax

Or with alias:

 Using Multiple Local Components

 Local-Components with Props

•  Works exactly like global components, but scoped locally

 Local Components with v-for

•  Very common in real projects

 Local vs Global Components (Important)

•  Use local components by default
•  Use global components only for base UI (buttons, icons)

 Common Use Cases

• Feature pages

• Dashboard widgets

• Page-specific modals

• Cards, lists, sections

 Common Mistakes

•  Forgetting to register component
•  Using global components unnecessarily
•  Wrong import path
•  Name mismatch in template

 Best Practices

•  Prefer local registration
•  Use PascalCase component names
•  Keep components small & focused
•  Register only what you use
•  Use global components sparingly
