+*** npm
+npm is especially cumbersome, for instance because by default it tries to install packages to =/gnu/store/=.
+
+In principle, one can set a prefix like this:
+#+begin_src conf :tangle ~/._npmrc
+prefix=/home/pavel/.npm-packages
+#+end_src
+
+But I also want to use node from conda occasionally, where prefix is already set correctly. So instead of tangling the above to the =~/.npmrc= directly, I set an environment variable in the profile:
+
+#+begin_src sh
+export NPM_CONFIG_USERCONFIG=$HOME/._npmrc
+#+end_src
+
+The variable is unset in a script in [[file:Guix.org::*conda][Guix.org]].

+Finally, I also want to have an ability to use global npm. Some settings for that are located in [[file:Console::*npm][Console.org]]. Here we want to unset =NPM_CONFIG_USERCONFIG= if there is npm available in the environment.
