Media Type Database, a large collection of MIME types and related metadata delivered as a single public JSON file. It is useful for looking up MIME information (such as known extensions, compressibility, and default charset) for handling files correctly in Node.js and web tooling.

Project status

  • Actively maintained: The repo shows a very recent upstream push (2026-06-01), and there have been versioned updates in 2025 and 2024, indicating ongoing work rather than maintenance-only.
  • Update cadence: Version updates appear periodic but not strictly regular (v1.52.0 in 2022, v1.53.0 in 2024, v1.54.0 in 2025), suggesting a cadence driven by batch refreshes to the MIME dataset and tooling rather than frequent releases.

Recent updates

  • v1.54.0

    3/18/2025

    v1.54.0 expands the mime type database with many new and updated entries (notably around Microsoft and Google Drive related types, plus additional file extensions/types). The maintenance/build tooling was updated to replace got with undici, and CI was modernized with an added lint job and a broader Node.js test matrix. Most changes are additive data updates, but there are some property behavior changes (for example, application/octet-stream compressible).

    BreakingFeatures

  • v1.53.0

    11/1/2024

    v1.53.0 updates mime-db’s generated MIME database and associated tooling. The documented highlights are JavaScript MIME type/extension corrections per RFC 9239, adding the .sql extension to application/sql, and CI/workflow maintenance (including a scorecard pipeline). Code changes also include broader refactors to the data generation scripts and a much larger MIME dataset refresh (additions and extension list changes) beyond what is individually called out in the release notes.

    Features

    Release 1.52.0 updates mime-db with additional MIME type entries and adds more filename extensions derived from IANA, including `.asc` for `application/pgp-keys` and further extensions for image and various XML related types. The diff also includes internal build-script and test adjustments, plus minor CI configuration changes.
