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.
