How to set debug mode on Windows?

[minhuaMS]

In the document, it says:

On Windows, use the corresponding command.

set DEBUG=express:* & node index.js

But when I run the command above in Windows Powershell or VS Code terminal, the error message:
Set-Variable : A positional parameter cannot be found that accepts argument 'node'.
At line:1 char:1

• set DEBUG=express:* `& node --experimental-json-modules index.js

•   + CategoryInfo          : InvalidArgument: (:) [Set-Variable], ParameterBindingException
    + FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.Commands.SetVariableCommand
  
  

Tried all the approaches I could find on Stackoverflow, no luck yet. Any suggestion?

try this

# windows powershell
$ $env:DEBUG="express:*"; node .\index.js
# windows cmd 
$ set debug=express:* && node index.js
# linux/Mac OS
$ DEBUG=express:* node index.js
