command-exists-promise
Node module to check if a command-line command exists.
Forked from command-exists.
Installation
# For npm users$ npm i command-exists-promise # For yarn users$ yarn add command-exists-promise
Usage
The function returns a promise that will resolve to true
if the command exists and false
if it doesn't.
On UNIX, the promise will resolve to true
if the command is a path to an executable file. On Windows, it will resolve to true
for any existing file.
Promise
const commandExists =
Await
const commandExists = try const exists = await if exists // The command exists else // The command doesn't exist catch err // Should never happen but better handle it just in case
