micromark-extension-mdxjs is a micromark extension that adds MDX.js syntax support to micromark, meant to be used inside MDX. It supports export/imports, expressions, and JSX, and it can disable some markdown features, useful when you want micromark to parse MDX content and you need JavaScript-aware syntax handling.
Project status
- The source appears to have been actively maintained in the past, but based on the evidence (last known published update in the provided summaries is 3.0.0 from 2023-10-19, and the last upstream push was 2024-09-02), it is effectively quiet/dormant relative to today (2026-06-09), with no evidenced updates in the last ~21 months.
- Update cadence is irregular: major changes clustered in 2020 to 2023 (0.x in late 2020, 1.x in 2021, 2.x in mid 2023, 3.x in late 2023), and then a longer gap with only an upstream push noted in 2024.
