Martin, All,

Great, thanls! :-)

You mean, http-server must be in the directory you want to serve? Or did
you mean that you just run /path/to/http-server and it will serve the
current directory?  (I guess the latter.)

OK, so why not make symlinks (or hadlinks) for each of them in /usr/bin
instead? Something like (untested):

    cd $(TARGET_DIR)/usr/bin; \
    for f in ../../usr/lib/node_modules/.bin/*; do \
        [ -f "$${f}" -a -x "$${f}" ] || continue; \
        ln -sf "$${f}" "$${f##*/}" || exit 1; \
    done
