binary-type

A simple package that provides the ability to check if a buffer matches a specific mimetype, and secondly the ability to guess a mimetype given a buffer.

Reference

matches(mimetype, buffer) => Boolean

Return true if the supplied buffer has a binary file signature that matches what is expected for the specified mimetype.

guess(buffer) => String

Run the supplied buffer through the various known mimetypes to attempt to determine it's mimetype (returned as a string value if found).

NOTE: Only a few file signatures have been implemented at this stage, but feel free to issue a pull request if you require additional types. A good resource of binary file signatures can be found at the following url:
