UI/UX professionals can use various techniques and tools to improve their designs. Designers need to be able to see the whole process and then work on the key components to make the product valuable and usable. Design systems are a key part of successful organizations. Moreover, an effective design system uses many elements or building blocks. The UI component library is one example of such an element.

A component library cannot define the entire design system. As part of a design team, UI/UX professionals will come across pattern libraries, component libraries, and design system daily. These terms should be understood and used with care, as they can cause confusion that could lead to problems in the design process.

UI Component Library

First, you need to know what is a component library. It is a collection UI design elements that are contained in a single folder or file. You can have buttons, popups, visuals, and fonts. This library is useful for creating consistent designs.

A UI component library is also a pattern library or component library. It contains all the components used in a website, software, or application and can be reused by developers.

These components can be used on multiple devices and platforms. To create a page on a website or screen in an app, developers need to copy these components’components’ code from the library.

The components are already coded, and there is little scope for developers to re-interpret, make small changes, or correct coding mistakes. It is limited to the essential components (i.e., Buttons, headings, and fields are the most common components. However, it can also contain complex modules (i.e., Navigation menu, forms, and sliders) and templates (i.e., homepage, service details page, check out page).


Design System

A design system is an interconnected platform that holds all design elements that can then be reused to create digital platforms.

It is essentially a combination of a design guide and component library that can be continuously and instantly updated. A design system is different from a component library because of its interconnectedness. This means that if a designer changes the look of a button, it will also update the code and where that code is implemented.

Organizations adopt a design system because it makes it easy to update multiple pages for different devices or platforms. This saves time and money when developing mobile apps for iOS and Android or creating hundreds of pages for a responsive site. It also maintains consistency in UI and UX design.

This is possible because of the “Atomic Design Method.” In this method, the components are broken down into the smallest element called atoms. These atoms combine to make molecules, organisms, and templates. Implementing changes is easier when you only need to modify the code and design of one item.

The design system’ssystem’s collaborative nature is another advantage. It is a platform, not a file. Also, multiple designers can collaborate simultaneously. Developers and other team members can also give feedback and ask questions about the same document. Also, design changes will be reflected in the code as the final output from the designer.

Additionally, like a design guide, design systems have descriptions and instructions on how to use specific components. This allows engineers and developers to understand their purpose.


What’s the difference between a design system and a component library?

There are many differences between a component list and a design system.

  1. Design systems include component libraries.
  2. Only UI elements are included in component libraries
  3. Design systems include policies and procedures
  4. Component libraries do not have standard documentation
  5. The entire design process is governed by design systems


Both UI component libraries and design systems adhere to the same design principles. However, it is important to understand their differences and scope. These terms are essential for creating efficient design systems. This will allow you to create comprehensive design systems that can add value to your end products.

A design system is a set of principles, guidelines, and tools for creating consistent user experiences across multiple channels or products. In fact, it defines the look and feel of the product by providing rules, guidelines, and reusable components. Design systems ensure consistency in branding, style, interactions, and other aspects of user experience.

On the other hand, a component library is focused on providing developers with reusable code components that can be implemented into applications faster and easier. Component libraries usually provide a selection of pre-defined UI elements or components, such as buttons, forms, tabs, etc. that can be reused several times within an application without needing to create them from scratch.

What are the similarities?

The main similarity between design systems and component libraries is that they both serve the purpose of enabling developers to create better user experiences by providing them with reusable components, tools, and guidelines. Both also allow teams to work faster and more efficiently, as developers don’tdon’t need to start from scratch when creating a new product or feature. Additionally, both design systems and component libraries are designed to provide users with consistent experiences across multiple channels or products.

Finally, both design systems and component libraries can be used together in order to ensure that a product has a unified look and feel while still being flexible enough to meet the needs of different users. By combining design principles, UI elements, and code components into one cohesive library, teams can easily create better user experiences that are both consistent and effective.



Design systems provide a unified set of principles and guidelines for shaping user experience across multiple channels or products. At the same time, component libraries enable developers to quickly and easily implement reusable code components within applications. Both are important tools for creating effective digital experiences.
