批处理文件调用 Node.js - 如何从 Node 设置 ERRORLEVEL

Question

我有一个调用节点程序的批处理文件：

@echo off

echo Starting Deploy.js: %date% %time%
echo CurrentDir: %CD%

node .deploy/deploy.js
IF %ERRORLEVEL% NEQ 0 goto error

echo Finished Deploy.js: %date% %time%

echo %~n0: Completed %date% %time%

goto end

:error
endlocal
echo An error has occurred during web site deployment.
call :exitSetErrorLevel
call :exitFromFunction 2>nul

:exitSetErrorLevel
exit /b 1

:exitFromFunction
()

:end
endlocal

I'd like to be able to have my node.js program be able to have it hit the error condition on failure of the application.

How do I trigger that in node.js?

I tried having my main function return 0 or 1, but it's not automatically setting the ERRORLEVEL.

What is the proper way to do this?

检查有关 process object 的node.js 文档。在您的情况下，您不需要回调函数，因此您可以简单地使用：

process.exit(666);

您可以在其中设置所需的退出代码而不是666
