Option

Description

Overwrite Service

If the Node.js service you want to deploy already exists, check this option, if you want to overwrite it.

Startup Service

To run, the Node.js service has to be started. Select this option, if you want the Node.js service to be started automatically right after its deployment.

Run 'npm install'

Select this option, if you want to run an 'npm install' after service deployment to get dependent Node.js packages (see Structure of a Node.js Service Repository further below).

Multiexcerpt

MultiExcerptName	npm_install

As per default, this 'npm install' does not run installer scripts. Check run scripts, if you want to execute npm installer scripts, but be aware of the fact that running scripts is a security vulnerability.
To inspect the logs of the 'npm install' command, switch to the deployed service and go to tab Logging (see also Logging of Node.js Services).

Preserve node_modules

Upon deployment of a Node.js service, the modules folder will get deleted, if existent. By setting this option you can keep these folders.
This can be useful , if you do not want to perform an npm install on deployment.

Instance Name

You can overwrite the Node.js service name here. This is helpful, if you e.g. want to deploy the very same service multiple times with different names.

After you have set the deployment options, deploy the service by clicking Upload.
If you have deployed a new service, it will be displayed in the navigation on the left, below the node instance, to which it has been deployed.
