What is the proper way to develop custom nodes and test them in watch mode?

I am trying to add to nodes_base folder and build docker image every time to use the node. npm run dev doesn’t start the service

Hi @Biprakanta_Pal,
welcome to the community :tada:

Did you follow our n8n docs? Like Creating Your First Node?

You have to execute the following in n8n’s root folder (not the packages/nodes_base folder).

# one time to init packages and dependencies
lerna bootstrap --hoist
npm run build
# while developing nodes
npm run dev

Does it work when executing in the root folder?
