Introducing Linked Child Files for Large Design Systems

Working with large design systems in Figma can sometimes lead to heavy memory usage and slower performance, especially in complex projects. To address this, I propose a Child File System in Figma, where child files are separate yet linked to a master file that holds all styles and variable declarations.

This concept is similar to WordPress child themes and would enable better performance and management of large design systems.

Proposed Features:

  1. Master and Child File Relationship:
  • A Master File serves as the single source of truth, containing all styles, components, and variable declarations.
  • Child Files link to the Master File and inherit its styles, variables, and components without duplicating them locally.
  1. Selective Syncing:
  • Designers can choose which parts of the master file (e.g., specific components or variable groups) to sync with child files.
  • Child files can override certain variables or components for specific use cases while maintaining the connection to the master file.
  1. Improved Performance:
  • By working on a child file that references the master file instead of loading the entire design system, memory usage and load times are significantly reduced.
  1. Dynamic Updates:
  • Changes in the Master File propagate to all linked child files.
  • Designers can opt to accept updates or maintain overrides for localized changes.
  1. Version Control:
  • Maintain a log of updates made to the master file and their impact on linked child files.

Use Cases:

  • Modular Design System Management:
    Teams working on different parts of a large project can focus on their specific child files while staying synced with the overarching design system.
  • Localized Customizations:
    Create child files for specific brands, regions, or products, inheriting most styles from the master while customizing only the necessary elements.
  • Improved Collaboration:
    Multiple designers can work on separate child files without affecting the master file’s performance or risking unintentional changes.

Benefits:

  • Performance Optimization:
    Reduces memory load by breaking the design system into manageable chunks.
  • Flexibility and Scalability:
    Supports complex workflows with easier file management and modular updates.
  • Consistency Across Projects:
    Ensures child files remain aligned with the master design system.

Potential Workflow Example:

  1. Create a Master File with core styles, variables, and components.
  2. Designers create Child Files linked to the master for specific modules, pages, or projects.
  3. Changes to the master file automatically sync to child files, or designers can selectively update their files.
  4. Child files load faster, and teams work more efficiently without duplicating resources.
