The goal is not to make every design-file component identical to its code counterpart; it is to make their names, supported choices, and intended behavior clear and traceable.
Start with shared foundations and a useful scope
Define the repeatable decisions that should apply across products: color, typography, effects, and spacing or layout rules. In Figma, styles can capture color, text, and effects, while variables can represent tokens. Figma supports either a single library file or a split structure; choose based on team and product needs rather than assuming one arrangement fits every organization. Figma’s library guidance explains the available structure.
Keep the first shared system focused on recurring patterns. A primitive such as a button or icon can serve as a building block; a composition combines pieces into a larger pattern. Some layout helpers may be useful in a design system without having a direct design-file component equivalent. Figma’s Simple Design System illustrates primitives, compositions, icons, and stories, but its structure is an example, not a requirement.
Choose what belongs in the shared library
- Include patterns that recur and have a clear purpose across files or products.
- Keep one-off product decisions local until there is a real reuse case.
- Make exceptions visible. When the same exception recurs, decide whether to add a supported variant, generalize the shared component, or keep it product-specific.
Model components around real usage choices
Create design components for repeated interface elements and patterns, then expose properties or variants for choices consumers actually need. Components provide reusable building blocks, and instances can receive updates from their main component. Use variants for mutually exclusive states where that prevents invalid combinations; independent boolean properties can allow combinations that should never occur. Figma’s library documentation and variants lesson describe these concepts.
#1 Best Overall
Before implementation, designers and engineers should agree on each component’s name, properties, intended application, and limitations. Use the same name in design and code when practical. The convention itself—camelCase, kebab-case, or another consistent form—is less important than shared vocabulary: a person looking at a design instance should be able to recognize the corresponding implementation. Figma makes this point in its guidance on defining a design system.
Align design properties with code props and states
For each design choice, identify the corresponding code prop, state, or documented limitation. If a design variant represents a disabled state, the code component needs an equivalent behavior or a clearly documented reason it does not. A matching name by itself does not guarantee matching visuals or behavior.
Publish a design library and consume its instances
Publish the selected components, styles, and variables as a library. Product files should use library instances instead of rebuilding similar local elements, so consumers can review library changes and apply updates intentionally. A single library may be practical for a small team or one product; separate libraries can make sense for distinct themes, product lines, platforms, or ownership boundaries. Figma leaves this organizational choice to the team. See Figma’s library guidance.
When to use one library or several
| Structure | Often a better fit when | Trade-off to consider |
|---|---|---|
| One shared library | A small team or single product can use the same foundations and components. | Consumers may see components that do not apply to their product or platform. |
| Multiple libraries | Products have separate themes, brands, platforms, or asset ownership. | Teams must clarify which library owns shared foundations and how changes are coordinated. |
These are decision criteria, not prescribed Figma configurations; choose the structure that keeps the right components accessible without making ownership ambiguous.

Connect design components to their code implementations
A mapping layer gives designers and developers a path from a design instance to the implementation. Figma Code Connect maps published library components to repository paths and names. A GitHub connection is optional; mappings can also be entered manually. If different platforms or frameworks have distinct implementations, a design component can map to more than one code component. Figma’s Code Connect documentation covers these options and associated access conditions, which can change.
Use Storybook when it is part of the workflow
Figma documents a Code Connect integration for Storybook: a story can reference its corresponding Figma component, allowing a design preview in Storybook and a connected snippet in Figma Dev Mode. Treat that connection as navigation and implementation context, not proof that the two versions are visually identical or cover every edge case. Verify the actual props, states, and behavior on both sides.
Maintain each platform mapping separately
If a component has React, iOS, Android, or other distinct implementations, check each mapping independently. One successful mapping does not establish that the other platform’s repository path, component name, or supported states are current. Figma’s Simple Design System repository also demonstrates one possible implementation path: scripts retrieve Figma variables and styles and convert them into CSS. Its React-oriented example is not a universal architecture or a requirement for connecting design and code.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Document usage and govern changes
Documentation should answer the questions a consumer has while choosing or implementing a component: what it is for, when to use it, which options are supported, and what constraints apply. Figma suggests several locations, including annotations in design files, component descriptions, naming structures, written guides, or a separate documentation site. If documentation lives elsewhere, link to it from the component where possible. Figma’s documentation guidance notes that a custom site needs ongoing maintenance; a design file or an existing Storybook or documentation tool may be more sustainable for a small team.
Best Value
Assign responsibility for proposing and approving changes, and define how consumers hear about them. A consistent release approach can distinguish breaking changes from nonbreaking additions and fixes, giving teams a clear way to plan adoption. Figma’s guidance describes major, minor, and patch categories as one example; use a scheme that fits your release process and communicate changes in terms consumers can act on.
Use a recurring drift check
Review the design and code relationship when components, tokens, or releases change. A practical check is:
- Confirm the design library is published and product files use its instances rather than detached or locally reconstructed copies.
- Compare component names and design properties with the code component’s props and states; investigate unsupported or unmatched choices.
- Check that each mapping points to the current repository component, and repeat the check for every intended platform or framework.
- When tokens change, review the code output or export. If automation generates CSS or another token format, verify the generated values before consumers adopt them.
- Update component descriptions and usage documentation when behavior, supported choices, or release status changes.
These checks make drift visible: a stale mapping, a detached instance, or outdated component guidance is a maintenance issue even if the interface still looks plausible in a screenshot.
