unique-filename

Generate a unique filename for use in temporary directories or caches.

const uniqueFilename = require('unique-filename') // returns something like: '/tmp/c5b28f47' const randomTmpfile = uniqueFilename(os.tmpdir()) // returns something like: '/tmp/my-test-51a7b48d' const randomPrefixedTmpfile = uniqueFilename(os.tmpdir(), 'my-test') // returns something like: '/my-tmp-dir/testing-7ddd44c0' const uniqueTmpfile = uniqueFilename('/my-tmp-dir', '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 reproducible way.
