Breaking

  • Requires Node.js 22
  • Dropped Node.js stream.Readable support from fileTypeFromStream() and fileTypeStream()
  • These now only accept a web ReadableStream. Migrate with Readable.toWeb() (nodejs.org): ```js // Before import fs from 'node:fs'; fileTypeFromStream(fs.createReadStream('file.mp4'));

// After import fs from 'node:fs'; import {Readable} from 'node:stream'; fileTypeFromStream(Readable.toWeb(fs.createReadStream('file.mp4'))); ```

  • Sub-exports (e.g. file-type/core) have been removed. Import everything from file-type directly.
  • The ReadableStreamWithFileType type has been removed. Use AnyWebReadableByteStreamWithFileType instead.
  • Several MIME types have been corrected or normalized:
Type Old MIME New MIME
lz application/x-lzip application/lzip
lnk application/x.ms.shortcut application/x-ms-shortcut
Apple Alias application/x.apple.alias application/x-ft-apple.alias
fbx application/x.autodesk.fbx application/x-ft-fbx
Draco application/vnd.google.draco application/x-ft-draco

MIME subtypes prefixed with x-ft- are custom types defined by this package (not IANA-registered).

Improvements

  • Added detection for Apple iWork files: .key (Keynote), .pages (Pages), .numbers (Numbers)

Fixes

  • Fixed LibreOffice OOXML files being incorrectly detected as ZIP when reading from streams
