Key Differences Between Design System And Component Library

Design System vs Component Library: Understand the key differences, their unique roles, and how each impacts your product's design efficiency.

With the rise of design systems, it’s easy to be overwhelmed. You might be wondering, What is a design system? Do I need one? What goes into creating a design system? What is a component library? What is the difference between a design system and a component library? How do I get started? If you are asking these questions, you’re not alone. Many teams new to design systems are unsure where to start, and for good reason. 

Design systems come with many benefits but require a lot of upfront work that can feel daunting, especially if you don't know what you're doing. What’s worse is that as design system tools and design-to-code tool gain popularity, they become more complex.

What is a Design System?

A design system is a collection of standards for managing design at scale. It merges components, documentation, and design principles to achieve efficiency and consistency across a product suite. Design systems enhance collaboration, streamline workflows, and maintain brand identity. 

They help teams create cohesive digital experiences. For example, a design system might include:

  • Reusable UI components include buttons, input boxes, and navigation menus.
  • A style guide with approved brand colors, fonts, and rules for using them.
  • Interaction patterns describe how certain elements behave, such as using a slide-out panel to avoid clutter.
  • A flexible grid system for laying out screens consistently.
  • Documentation that specifies how to use particular elements, such as keeping login icons in the top right corner of a desktop interface.
  • Lists of icons, what they mean, and when to use them.
  • Content guidelines that describe how and when to use text. For example, a design system might standardize whether to refer to the user as “you” or “the user.”
  • Rules for when to use icons and when to use text as labels.
  • Visual guidelines for where certain types of call-to-action buttons should be.
  • Rules for using things like auto-save vs explicit save/cancel buttons. There are many other guidelines that a design system might have. 

Google’s Material Design is an example of a consistent design system. It consists of different types of elements and guidance on when and how to use each component. 

Design Systems for Voice and Behavior

Design systems extend beyond visually driven tools; they apply to voice-controlled systems, too. These systems focus on content and behavior. They provide different but equally valuable features. Effective design systems evolve with time. They adapt as the needs of a product or product suite change. 

Toolkit for Developers and Designers

Ideally, elements of a design system are code pieces developers can use in interfaces. This helps build features or prototypes faster. In other cases, they are design elements in prototyping tools for designers to reuse.

A Look Inside a Design System: Governance

Governance plays a key part in maintaining the integrity of your design system. It’s akin to having traffic rules; without them, there’d be chaos on our roads. Similarly, governance establishes best practices and ensures everyone adheres to them while using the design system. 

This can include how components should be used or when new ones can be added. With good governance policies, you avoid turning your clean and organized library into a Wild West. Design tokens, essential small individual pieces of style information such as color values or spacing units (think hex codes), play their part within this governed ecosystem. 

They make sure designs stay consistent by dictating specific aspects throughout all applications under one umbrella, similar to following a uniform dress code at school, ensuring unity amongst students despite the different grades or classes they belong to.

A component library is a collection of pre-designed and pre-built user interface elements that create user interfaces for digital products, such as websites and applications, with a unified look. These libraries include various pre-made UI elements, such as:

  • Buttons
  • Forms
  • Navigation menus
  • Icons and many more

Each is designed with a consistent look and feel. UI component libraries are handy in collaborative design and development environments, as they help ensure that all team members are using the exact source of truth and that the end product maintains a professional and polished appearance. 

Component libraries can reduce the risk of product variations or components in different places. They handle the source code for UI elements and usually leverage CSS and JavaScript. React is a prime example of a popular open-source framework. 

The Importance of Component Libraries  

Component libraries play an integral role in design, significantly contributing to creating successful products and services. Implementing a component library can save time and resources, eliminating the need for developers to recreate common elements consistently. 

This improves overall efficiency, allowing teams to focus more on functionality than design implementation.  

Maintaining Brand Consistency and User Experience

Beyond efficiency, component libraries also lay the groundwork for coherency and consistency. Using reusable components, brands ensure their digital presence maintains a uniform look and feel across different platforms or devices. This consistency reinforces brand identity while providing users with a seamless experience.  

Fostering Collaboration and Streamlining Communication

A well-curated component library can also serve as an effective tool for fostering collaboration within teams. It acts as a shared resource where designers can contribute new ideas or components, ensuring everyone is aligned toward one vision. In turn, this makes communication smoother among designers and engineers alike.  

Benefits of Component Libraries  

A component library is a toolbox filled with versatile library components for designers and developers. Like how a carpenter would reach into their toolbox for the right tool, digital product teams access design components for their projects. What are the advantages that come with utilizing a component library?  

Increased Efficiency and Faster Development

The first significant benefit is time-saving. Atlassian’s design system, which includes an extensive component library, has been instrumental in helping their team build products faster by reusing code snippets rather than starting from scratch every time.  

Enhanced User Experience and Brand Consistency

But it’s not just about speed; consistency plays a huge role too. Using familiar elements across different projects ensures a consistent user experience. Imagine being able to familiarize your users as they navigate through various parts of your app or website because you’ve reused components.  

Improved Team Collaboration and Communication

In addition to saving time and promoting consistency, component libraries can foster better team collaboration. Using the same building blocks (components) makes communication more effective and less prone to misunderstanding.  

Scalability

With well-defined UI components, scaling up becomes much more manageable as new features can be built using existing elements without reinventing the wheel each time.  

Saves Time

Having ready-to-use pieces at hand allows quicker project completion. Promotes Consistency: Repeated use creates familiar interfaces, resulting in smoother user journeys. 

Fosters Collaboration

Shared understanding amongst team members leads to improved efficiency. 

Eases Scalability

Growth gets simpler when established systems are in place.

What Are The Key Differences Between Design System And Component Library?

employees on a laptop - Design System vs Component Library

A component library is a collection of reusable UI elements. It’s super handy for quickly assembling interfaces with consistent, pre-built pieces. Think of it as a toolbox for your design project. Inside, you’ll find all the essentials:

  • Buttons
  • Cards
  • Modals
  • Many more

Each component follows the same design guidelines and codebase, ensuring consistency across your app. When you need a button for your project, just grab one from the library and drop it into your design. This saves you time because you don’t have to build these elements from scratch every time. 

For example, let’s say you’re designing a login page. Instead of designing and coding each button and input field from scratch, you pull these components from the library, knowing they’ll look and behave consistently with the rest of your app.

Design System: A Detailed Recipe Book for Consistency

Think of a design system as a detailed recipe book that gives you the ingredients (the components) and instructions on how to use them (the guidelines). The design system is like a detailed recipe book that gives you the ingredients (the components) and instructions on how to use them (the guidelines). 

It provides the reasoning behind design decisions, ensuring everyone on the team, from designers to developers, is on the same page. This ensures that your app has a cohesive look and feel, no matter how many people are working on it. Ensuring Cohesive Look and Feel with Design Guidelines.

For instance, if you’re designing a new feature, the design system will guide you on which colors to use, how much spacing to apply between elements, and the overall user experience. It’s the overarching strategy that maintains the integrity of your brand and user experience.

Component Library vs. Design System: Building Blocks and Vision

A component library is a collection of reusable UI elements. It’s super handy for quickly assembling interfaces with consistent, pre-built pieces. A design system is a comprehensive framework that includes the component library and also provides the guidelines, principles, and best practices to ensure a cohesive and consistent design across the entire product. 

Both are crucial for efficient and consistent design work. Still, while the component library is more about the practical building blocks, the design system is about the overall vision and rules governing how those blocks should be used.

The Role of a Component Library in the Design System Process

Imagine trying to create a cohesive user experience when every designer on your team is inventing their buttons, sliders, or fonts. A component library eliminates this chaos by providing a single source of truth for all UI elements. Designers and developers can pick pre-approved components, ensuring every product looks and feels uniform. 

This consistency enhances usability and strengthens your brand identity, as users experience the same design language across all touchpoints.

Providing Shareable Resources

One of the standout features of a component library is its shareability. It acts as a centralized hub accessible to everyone involved in product development. Whether a team is working on a mobile app or a web platform, they can pull from the same repository of design elements. This is especially valuable in large organizations with multiple teams working on overlapping projects. 

Shareable resources reduce duplication of effort, allowing designers to focus on innovation rather than reinventing the wheel.

Saving Time and Effort

By having reusable components readily available, teams can save significant time off project timelines. For instance, instead of creating new icons, dropdown menus, or buttons from scratch, designers can simply grab these elements from the library, tweak them if necessary, and incorporate them into their designs. 

This speeds up the design process and ensures that components remain consistent across projects. Developers, too, benefit by having code-ready components that are easy to implement.

Developing a Rich Resource

A robust component library becomes a treasure trove of design assets over time. It’s not just a static repository; it grows and evolves within the organization. As new elements are created and refined, they are added to the library, enriching the resource pool. 

This provides a foundation for future projects and informs the design system's creation of rules and guidelines. Together with pattern libraries and style guides, the component library forms a comprehensive toolkit that enhances productivity and creativity.

Improving Team Collaboration

A lesser-discussed but equally significant benefit of a component library is its ability to foster collaboration. When designers contribute their best work to the library, it becomes a shared resource that reflects the team's collective expertise. 

Feedback mechanisms within the library allow for open communication, enabling designers to collaboratively improve and iterate on components. This culture of shared ownership enhances the library's quality and strengthens the team’s cohesion.

Elevating the Design System Process

A component library elevates the entire design system process as a central pillar of efficiency and consistency. It bridges the gap between design and development, ensures project uniformity, and empowers teams to work faster and wiser. 

Whether you’re a startup building your first digital product or an enterprise managing complex systems, the role of a component library is indispensable in achieving design excellence.
