"postbuild" commnad can't work in Windows

[KaminoRyo]

Hi, I try to run basic-starter-api-gateway-v2-typescript example.
However, the postbuild command uses the cp command and does not work on Windows.
If you don't want to depend on the OS, would it be better to create a copy script file with node.js and run it....

I'll take a look

Umm...I use powershell (VSCode's terminal) and run npm run setupcommand.
I didn't know that, but cp command can be used in Powershell (an alias for the Copy-Item command is set).
However, It doesn't seem to work with npm commands.

'cp' は、内部コマンドまたは外部コマンド、
操作可能なプログラムまたはバッチ ファイルとして認識されていません。 
(English: 'cp' is an internal or external command,
It is not recognized as an operational program or batch file.)

I've looked into it, but there doesn't seem to be an easy way to solve the problem without relying on external libraries or creating script files. npm command uses cmd.exe(command-prompt) in Windows.....
Probably on Windows the postbuild command will look like this.

    "postbuild": "echo d | xcopy /Y /E src\\views\\ dist\\views & xcopy /Y package*json dist\\ & xcopy /Y src\\code-genie-logo.png dist\\ ",
