nephele/src/compressedMediaTypes.ts

Highly customizable and extensible WebDAV server for Node.js and Express.

// If a format can be either compressed or uncompressed, this class reports it
// as uncompressed.
// For example: PSD files are compressed by default, but that can be turned off.

// If a format contains data that is not compressed, but compression would be
// completely ineffective (such as encrypted files), this class reports it as
// compressed.

// All mime types are completely lowercased.

// Most of this info came from https://fileinfo.com/ and https://www.loc.gov/search/
