function realpath
Usage in Deno
```typescript import { realpath } from "node:node__fs--promises.d.ts"; ```
realpath(path: PathLike,options?: ,): Promise<string>
Determines the actual location of `path` using the same semantics as the `fs.realpath.native()` function.
Only paths that can be converted to UTF8 strings are supported.
The optional `options` argument can be a string specifying an encoding, or an
object with an `encoding` property specifying the character encoding to use for
the path. If the `encoding` is set to `'buffer'`, the path returned will be
passed as a `Buffer` object.
On Linux, when Node.js is linked against musl libc, the procfs file system must
be mounted on `/proc` in order for this function to work. Glibc does not have
this restriction.
path: PathLike
Promise<string>
Fulfills with the resolved path upon success.
realpath(path: PathLike,options: BufferEncodingOption,): Promise<Buffer>
Asynchronous realpath(3) - return the canonicalized absolute pathname.
path: PathLike
A path to a file. If a URL is provided, it must use the `file:` protocol.
options: BufferEncodingOption
The encoding (or an object specifying the encoding), used as the encoding of the result. If not provided, `'utf8'` is used.
Promise<Buffer>
realpath(path: PathLike,options?: ,): Promise<string | Buffer>
Asynchronous realpath(3) - return the canonicalized absolute pathname.
path: PathLike
A path to a file. If a URL is provided, it must use the `file:` protocol.
