Lisi Urday implemented experimental Vue JSX and TSX support in the Biome repository, enabling parsing and validation of JSX and TSX within Vue components behind a feature flag. Using JavaScript, Rust, and Vue.js, Lisi expanded Biome’s embedded script parsing to recognize and process JSX and TSX syntax, laying the groundwork for broader tooling and future general availability. The work included developing dedicated tests to cover new Vue JSX and TSX flows, ensuring stability and regression safety. This feature allows frontline teams to leverage JSX and TSX in Vue files, improving code quality checks and validation across the Vue ecosystem.
