HI,

is there any workflow which automatically catches nodes from the palette when defined in packeage.json?

What i want to do is move my flows from a local instance to a docker container. so i need to install all nodes which i already installed again?  
I think i can also copy the node\_module folder but therefore i need to update several nodes.  
Is there any way to install them while docker compose?

Thx

What you need to do is to copy package.json and package-lock.json. Then if you go into the folder where your flows file is and run `npm install`. That will install the nodes you need. At least that is how you would do it in a normal installation. It may be different in a Docker environment.

package.json defines which nodes to install (with various constraints on versions).  
package-lock.json defines exactly which versions to install. If you always want to install the latest versions then you don't need the lock file.

thank you.

that gives me a better understanding and i think i am familiar now with how to solve this in docker container.
