Parcel View vs. Component

When building modern web applications, developers often hear the terms "parcel view" and "component." At first glance, these terms may seem similar, but they refer to two different things in UI (User Interface) development.

Understanding these concepts is crucial because they help developers build structured, scalable, and efficient applications. Whether you are working with frameworks like React, Angular, or Vue, knowing the difference between a parcel view and a component will help you design better applications.

In this guide, we will explore:

What a parcel view is and how it is used.
What a component is and its role in development.

- The key differences between parcel views and components.

When to use each approach.
How they work together in real-world applications.

Let’s dive in!

What is a Parcel View?

A parcel view is a section of a webpage or an application that is treated as a separate visual unit. Think of it as a specific part of the layout that is designed to display data in a predefined way.

A parcel view is mainly responsible for presentation—this means it focuses on how things look rather than how they work.

Key Features of Parcel Views

They display information but do not handle complex interactions.
They are often pre-designed and static.
They do not manage business logic or make decisions.

They are layout-focused and help organize content.

They are typically used for visually structured sections in applications.

Where Are Parcel Views Used?

Parcel views are commonly found in applications where displaying structured data is important. Examples include:

E-commerce websites: A section showing product categories or featured items.
Dashboards: A summary section showing key statistics.
News feeds: A list of articles displayed in a specific order.

Landing pages: Sections with banners, promotional content, or testimonials.

Example of a Parcel View

Imagine you are building an e-commerce homepage. You have a section displaying a grid of featured products. This section:

Only shows data (e.g., product images, prices, and names).
Does not have buttons for adding products to the cart.
Is designed to fit the layout of the homepage.

This featured product section is a parcel view because it focuses on presentation and structure rather than interactivity.

What is a Component?

A component is a reusable, self-contained building block of a UI. Unlike parcel views, components are more powerful because they can handle:

Logic (e.g., fetching and managing data).
State (e.g., keeping track of user interactions).
User interactions (e.g., clicking buttons, entering input).

Reusability (they can be used in different parts of an application).

Key Features of Components

They can handle logic and state.
They respond to user actions (e.g., button clicks, and form submissions).
They are designed to be reused across different pages.

They can be composed together to build complex interfaces.

Where Are Components Used?

Components are used in almost every modern web application. Examples include:

Buttons: A simple button that can be used in multiple places.
Forms: A login form that validates user input.
Modals: A popup window that appears when a user clicks a button.

Interactive charts: A graph that updates dynamically based on user input.

Example of a Component

Returning to our e-commerce homepage example, imagine a product card inside the featured product grid. This card has:

A product image and name.
A button to add the product to the cart.
A rating system that allows users to leave reviews.

This product card is a component because it:

Has logic (e.g., adding a product to the cart).
Responds to user actions (e.g., clicking a button).
Can be reused across different pages.

Key Differences Between Parcel Views and Components

When to Use Parcel Views vs. Components

Use Parcel Views When

The focus is on layout – For example: Displaying a static list of products or images.
Data is already pre-processed – Example: A dashboard summary showing statistics.
No interactivity is required – Example: A homepage banner that does not change.

Use Components When

You need interactivity – Example: A form with validation.
Reusability is important – Example: A button component used in multiple places.
Dynamic data is required – Example: A table fetching API data.

How Parcel Views and Components Work Together

Parcel views and components are not competitors—they work together in UI development.

A parcel view provides structure and layout.
A component makes the individual parts functional.

For example, a dashboard page might be a parcel view, but the **widgets **(charts, buttons, tables) are components.

Why This Matters for Developers

Understanding the difference between parcel views and components helps developers:

Write cleaner, more organized code.
Build reusable and maintainable applications.
Create scalable UI architectures.

With over 60% of modern web applications using frameworks like React, Angular, and Vue (according to the Stack Overflow Developer Survey 2024), knowing how to properly use components and parcel views is essential.

Conclusion

Parcel views and components serve different purposes but work together to create great user interfaces. Think of a parcel view as the blueprint of a house—it defines the layout. A component is like the bricks, windows, and doors—it makes the house functional.
