We're currently moving the build of our UI projects (3 in total) to Grunt. To ease the transition I'd like to provide a bat file that will run npm install for each project, however I'd like to know if something went wrong when issuing this command. It's merely sugar coating that I'm after, I know npm echoes errors out, but I'd like some easier messages for the members on my team that are not familiar with npm and node.
Is there a way to check whether npm has run into an error and to subsequently halt the bat file? For example, if node is not installed, I simply check for %ERRORLEVEL% to be 1. If this is the case, I echo out some instructions and exit the execution. The problem I'm having is that %ERRORLEVEL% is not set to 1 when an error occurs during a npm install.
Any help appreciated!
