unique-filename
Generate a unique filename for use in temporary directories or caches.
var uniqueFilename = require('unique-filename')
// returns something like: /tmp/912ec803b2ce49e4a541068d495ab570
var randomTmpfile = uniqueFilename(os.tmpdir())
// returns something like: /tmp/my-test-912ec803b2ce49e4a541068d495ab570
var randomPrefixedTmpfile = uniqueFilename(os.tmpdir(), 'my-test')
var uniqueTmpfile = uniqueFilename('/tmp', 'testing', '/my/thing/to/uniq/on')
uniqueFilename(dir, fileprefix, uniqstr) → String
Returns the full path of a unique filename that looks like:
dir/prefix-7ddd44c0
or dir/7ddd44c0
dir – The path you want the filename in. os.tmpdir()
is a good choice for this.
fileprefix – A string to append prior to the unique part of the filename.
The parameter is required if uniqstr is also passed in but is otherwise
optional and can be undefined
/null
/''
. If present and not empty
then this string plus a hyphen are prepended to the unique part.
uniqstr – Optional, if not passed the unique part of the resulting filename will be random. If passed in it will be generated from this string in a reproducable way.
