During January 2025, Kandy enhanced the HTML formatter in the biomejs/biome repository to improve readability for elements with multiple attributes in multiline configurations. By introducing a targeted condition, the formatter now inserts a hard line break only when the attribute position is multiline and more than one attribute is present, aligning output with established formatting rules. This change, implemented in Rust and leveraging skills in code refactoring and testing, focused on minimizing code surface area to reduce review complexity and risk. Kandy’s work addressed maintainability and developer productivity, demonstrating a thoughtful approach to formatter design and JavaScript/TypeScript tooling integration.
