mkdtemp

Create a unique temporary directory with the given prefix. Uses OS random source (/dev/urandom on Unix, BCryptGenRandom on Windows) with up to 10 retries.

Basic usage


import { mkdtemp } from '@rush-fs/core'
 
const dir = await mkdtemp('/tmp/myapp-')
console.log(dir) // e.g. /tmp/myapp-abc123

Methods

`mkdtemp(prefix)`

Async. Returns Promise<string> (the created directory path).

Argument	Type	Description
`prefix`	string	Prefix for the directory name (e.g. path + trailing separator).

`mkdtempSync(prefix)`

Sync. Returns string or throws.

Performance

Single syscall plus random generation; on par with Node.js. See Benchmarks.

Notes

Prefix: Include a trailing path separator (e.g. os.tmpdir() + '/') so the random part is the last path component; same as Node.js.
Cleanup: Caller is responsible for removing the directory when done (e.g. rm(dir, { recursive: true })).
