A tale of two parameter architectures—and how we unified them

Summary

The article outlines the challenges faced by Figma in managing two distinct parameter architectures for component properties and variables, which led to user confusion and inconsistencies. It describes the process of unifying these architectures to create a single, scalable system that enhances design consistency and developer efficiency. Key improvements include a shared data model for parameter types and bindings, as well as a standardized runtime for parameter updates, which collectively streamline the design process and prepare for future product enhancements.

Key Learnings

• 1The importance of unifying parameter architectures to eliminate inconsistencies and improve user experience in design tools.
• 2How scoped and global parametrization can be effectively managed within a single framework to enhance design scalability.
• 3The critical role of a shared data model in facilitating interoperability between different parameter systems.
• 4The necessity of a standardized runtime for managing dynamic behavior in design applications, ensuring consistent updates across all parameter systems.
• 5The impact of improved invalidation processes on performance and user experience in design workflows.
