However, it should be noted that inside npm-scripts npm sets its own environment variables and Node prefers those lowercase versions over any uppercase ones that you might set. The config values are case-insensitive, so NPM_CONFIG_FOO=bar works the same as the lowercase version shown earlier. Any environment configurations that you do not given a value will be given the value of true. For instance, when you put npm_config_foo=bar in your environment, it will set the foo configuration parameter to bar. Finally, -name1 -name2 -bar will set both configuration parameters to true, and the bar is taken as a command argument.Īny environment variables that start with npm_config_ is interpreted as a configuration parameter. When you use -flag without specifying any value, will make the value to be set to true.Įxample: -name1 -name2 will set both configuration parameters to true, while -name1 -name2 will set name1 to true, and name2 to bar. A - argument will tell the cli parser to stop reading flags. When you put -foo bar on the command line, the foo configuration will be set to ?bar?.
