Is it necessary to connect the drawings and the running version using Figma Code Connect?
This question only makes sense when you know who you are handing the design over to and what they are using to code.
You need to set up Figma Code Connect when your team separates roles: designers on one side, developers on the other, and there is a real component library in the code repository. At that point, Code Connect ensures that Dev Mode (the developer view mode in Figma) displays the actual component code instead of generic auto-generated code, reducing discrepancies between the running version and the design. If only one person is both designing and coding, or if the component library in the code is not yet available, there is no rush.
- a team separating design and programming roles, already having a real component library
- want to reduce friction when transferring designs to production
- one person handling both design and code
- Small products or those without components in the code.
Figma Code Connect (the tool that links designs to live code) is not something that needs to be set up right from the start. It has a clear position in the lifecycle of a design system: after real components are in the code, after the team has separated design and programming roles. Setting it up earlier than that is setting it up in a void.
What does Code Connect actually do?
Dev Mode is a view mode specifically for developers in Figma: they enter here to retrieve design specifications and reference code. The issue is that Figma by default generates generic code that does not match the component library the team is actually using.
Code Connect addresses that issue precisely. It links each component in Figma with the corresponding component in the code repository, so when a developer selects a component in the design, Dev Mode displays the correct code snippet from their repository, not auto-generated code. The result: the developer can copy that code snippet and use it immediately, without having to translate it from the design.
It is important to be direct: Code Connect does not write components itself. It only connects and displays what already exists. If there are no components in the code, there is nothing to connect.
When to need, when not needed
Need to establish when: the team has clearly separated roles between design and programming, a component library in the code has formed, and friction during handover is a real issue. At this point, the Dev Mode generates confusing code, and developers must guess what the auto-generated component corresponds to in the actual codebase.
No need when: one person is both designing and coding, so there are no deliverables, the product is small and lacks a component library in the code, or the team has not agreed on component naming between Figma and the code repository. Setting up at this point is labor-intensive and does not solve the actual problem.
Two setups and which one to choose
Figma provides two ways to set up Code Connect.
- Interface in Figma: set up directly in the application, no need for code, not dependent on programming languages. Suitable for quick testing or when the design team works independently without developer support.
- Command line: more precise because it maps each property of the component, for example, linking the "variant" property in Figma with the corresponding prop in React. Suitable when the component has multiple states and requires detailed control. Supports React, Web Components, and some other types.
Practical advice: start with a Figma interface to validate the idea, then switch to code when you need to map properties.
Common errors when implementing
- Setup before having components in the code: there is nothing to connect, time spent yields no results.
- Expecting it to generate components automatically: Code Connect currently has existing code, without writing new code. Misunderstanding this leads to disappointment in the wrong place.
- Connect once and forget: components in the code are renamed or structured, mapping in Code Connect does not keep up, and Dev Mode starts showing misaligned code. Code Connect should be viewed as part of the component update process, not a one-time task.
The viewpoint of Sinh Vũ
Sinh Vũ positions Figma Code Connect in Phase 2 of the design system journey, along with the component library and Storybook documentation (a tool for writing component documentation). This is the correct position: after the real components are in the codebase, and after the team is large enough to hand over to become a friction point.
The operational goal is for designers and developers to view the same component, use the same name, and apply the same code. Code Connect is the tool that helps achieve this in Figma. However, the tool only makes sense when the foundation is set: tokens (base design values like color, font size, spacing) are synchronized, and components have consistent names on both sides.
Connect the design to the live version one-to-one so that designers and developers see the same component, not two different versions of the same intention.

Frequently asked questions
Does Code Connect write code components for itself?
No. Code Connect only links components already in your code repository with the corresponding components in Figma, then displays that code in Dev Mode. If the component has not been written, there is nothing to link and display.
Is it better to set up through the Figma interface or via command line?
The Figma interface (built into Figma) is faster and does not require command line knowledge, suitable for when you want to set up a trial. The command line is more precise because it maps each property of the component, suitable when the team is clear about the component structure and wants detailed control.
Once set up, is there a need to update it?
Necessary. When components in the code change names, attributes, or structures, the mapping in Code Connect needs to be updated accordingly. Forgetting this step causes Dev Mode to display old code, misaligned with the actual running component.
