An async libmagic binding for node.js for detecting content types by data inspection.

(constructor)([< mixed >magicSource][, < Integer >flags]) - Creates and returns a new Magic instance. magicSource
(if specified) can either be a path string that points to a (compatible) magic file to use or it can be a Buffer containing the contents of a (compatible) magic file. If magicSource
is not a string and not false
, the bundled magic file will be used. If magicSource
is false
, mmmagic will default to searching for a magic file to use (order of magic file searching: MAGIC
env var -> various file system paths (see man file
)). flags is a bitmask with the following valid values (available as constants on require('mmmagic')
):
detectFile(< String >path, < Function >callback) - (void) - Inspects the file pointed at by path. The callback receives two arguments: an < Error > object in case of error (null otherwise), and a < String > containing the result of the inspection.
detect(< Buffer >data, < Function >callback) - (void) - Inspects the contents of data. The callback receives two arguments: an < Error > object in case of error (null otherwise), and a < String > containing the result of the inspection.
