Usage in Deno
import { type WASIOptions } from "node:wasi";
args: string[] | undefined
An array of strings that the WebAssembly application will see as command line arguments. The first argument is the virtual path to the WASI command itself.
env: object | undefined
An object similar to process.env that the WebAssembly
application will see as its environment.
preopens: Dict<string> | undefined
This object represents the WebAssembly application's
sandbox directory structure. The string keys of preopens are treated as
directories within the sandbox. The corresponding values in preopens are
the real paths to those directories on the host machine.
returnOnExit: boolean | undefined
By default, when WASI applications call __wasi_proc_exit()
wasi.start() will return with the exit code specified rather than terminatng the process.
Setting this option to false will cause the Node.js process to exit with
the specified exit code instead.
stdin: number | undefined
The file descriptor used as standard input in the WebAssembly application.
stdout: number | undefined
The file descriptor used as standard output in the WebAssembly application.
stderr: number | undefined
The file descriptor used as standard error in the WebAssembly application.

Currently the only supported versions are 'unstable' and 'preview1'. This option is mandatory.
