The node binary searches for packages in a number of locations, the last of which is $PREFIX/lib/node (here: /usr/lib/node) from the list of GLOBAL_FOLDERS [1]. Change the installation directory for all packages depending on npm.bbclass to that location. This removes the need to define the NODE_PATH variable to the non-standard /usr/lib/node_modules value. While the Tips for Package Managers [2] discusses installing packages to /usr/lib/node_modules/<name>/<version>, this has several drawbacks: * it does not work for the REPL as mentioned in the documentation * it also does not work for any code _not_ installed as a global package under /usr/lib/node_modules (e.g. /usr/share/foo.js will not find any packages below /usr/lib) * using the non-default location and then having to set NODE_PATH barely saves any time: there are only two file-system lookups (to the legacy $HOME/.node_modules and $HOME/.node_libraries) directories before the library would be found And the suggestion was made in the context of deduping the node_modules tree by installing all packages in a flat hierarchy and using symlinks to the correct version of each dependency. This is not what OpenEmbedded does, so none of those benefits (deduping, cleaner packages) are being had by shifting the installation directory to /usr/lib/node_modules.
