Mimoza

Mimoza is a tiny but comprehensive MIME tools library. Features:

• Resolving mime type by file path/name/extention (with fallback for unknown cases).
• Finding file extention by mime type.
• Checking if mime type (or file) can be compressed.
• Checking if mime type has text content (if you wish to force UTF-8 encoding)
• You can have multimple instances with different configs.
• Works in browser too (AMD module).

See detailed API docs.
