During February 2026, João Pedro Schmitz enhanced the oxc-project/oxc repository by developing targeted improvements to its React linter. He introduced support for the fetchPriority attribute, enabling the linter to accurately recognize and validate this performance-related HTML property in React codebases. Working primarily with Rust, HTML, and React, João updated the no_unknown_property lint rule to reduce false positives and ensure alignment with WHATWG HTML specifications. His work involved end-to-end changes, from rule configuration to commit-level documentation, resulting in smoother developer workflows, improved code quality, and more reliable static analysis for teams maintaining modern UI applications.
