+# Load the version of node for an app, and set variables.
+#
+# ynh_use_nodejs has to be used in any app scripts before using node for the first time.
+# This helper will provide alias and variables to use in your scripts.
+#
+# To use npm or node, use the alias `ynh_npm` and `ynh_node`
+# Those alias will use the correct version installed for the app
+# For example: use `ynh_npm install` instead of `npm install`
+#
+# With `sudo` or `ynh_exec_as`, use instead the fallback variables `$ynh_npm` and `$ynh_node`
+# And propagate $PATH to sudo with $ynh_node_load_PATH
+# Exemple: `ynh_exec_as $app $ynh_node_load_PATH $ynh_npm install`
+#
+# $PATH contains the path of the requested version of node.
+# However, $PATH is duplicated into $node_PATH to outlast any manipulation of $PATH
+# You can use the variable `$ynh_node_load_PATH` to quickly load your node version
+#  in $PATH for an usage into a separate script.
+# Exemple: $ynh_node_load_PATH $final_path/script_that_use_npm.sh`
+#
+#
+# Finally, to start a nodejs service with the correct version, 2 solutions
+#  Either the app is dependent of node or npm, but does not called it directly.
+#  In such situation, you need to load PATH
+#    `Environment="__NODE_ENV_PATH__"`
+#    `ExecStart=__FINALPATH__/my_app`
+#     You will replace __NODE_ENV_PATH__ with $ynh_node_load_PATH
+#
+#  Or node start the app directly, then you don't need to load the PATH variable
+#    `ExecStart=__YNH_NODE__ my_app run`
+#     You will replace __YNH_NODE__ with $ynh_node
+#
+#
+# 2 other variables are also available
+#   - $nodejs_path: The absolute path to node binaries for the chosen version.
+#   - $nodejs_version: Just the version number of node for this app. Stored as 'nodejs_version' in settings.yml.

+### - specify a custom command to check the status of the service (c.f. --test_status)

+### - specify a custom command to check / validate the configuration of the service (c.f. --test_conf)
