Detecting Expanded MIME Types in Go

In Golang, the http.DetectContentType function in the net/http package provides content type detection for a limited range of types. For additional file types, such as docx, doc, xls, xlsx, ppt, pps, odt, ods, and odp, conventional extension-based detection methods may not suffice due to the shared ZIP signature of these files.

To address this challenge, several packages have emerged that enable MIME type detection based on content analysis:

1. Filetype

• Pure Go
• Extensible for new MIME types
• Limited MIME type support
• Potential issues with files that have multiple possible MIME types

2. Magicmime

• Requires libmagic-dev installation
• Extensive MIME type support
• Extensible, but with some complexity
• Thread safety concerns

3. Mimetype

• Pure Go
• Intermediate MIME type support
• Thread safe
• Extensible

Based on these options, selecting the most appropriate package depends on specific requirements such as the number of detected MIME types, thread safety, and extensibility.
