I'm going to install a node "node-red-node-email" additionally in node-red using Enviroment Variable instead of using npm " npm install node-red-node-email". I don't find the list of environment variable used for nod-red.

I'm looking for similar to grafana environment variables list in the below url: ([https://grafana.com/docs/grafana/latest/installation/configuration/](https://grafana.com/docs/grafana/latest/installation/configuration/) )

Could you please me on this installation via Environment variable?

There is no such environment variable.

To install extra nodes you either:

1. Run npm install
2. Use the palette manager in the editor
3. Build your own docker image after adding the nodes you want to your package.json. This is described in the docker image readme.
