@file-type/plus

In addition to file-type, which focuses on mostly binary file signature detection, @file-type/plus also supports structured and container-based formats such as:

• CFBF compound documents, such as .doc, .xls, .ppt, .pub
• PDF subtypes, such as Adobe Illustrator .ai
• XML-based formats, such as SVG, SMIL, RSS

It behaves exactly like file-type, but automatically enables:

• @file-type/pdf
• @file-type/xml
• @file-type/cfbf

Install

npm install @file-type/plus
