To switch to a different environment, you need to set the NODE_ENV environment variable which will cause the frontend to use a different environment configuration json.

Powershell

• Get-Childitem env:NODE_ENV - Gets current environment (if there is any)
• Set-Item -path env:NODE_ENV -value 'test' Sets test environment
• Set-Item -path env:NODE_ENV -value '' Delete environment variable

Conemu

• Settings > Startup > Environment
• set NODE_ENV=test

CMD

• set NODE_ENV=test

OSX

• export NODE_ENV=test
