Setting your Node version
Controlling the Node version for your Rails application
We automatically install the latest release of Node version 10.x.x when we set up your Rack/Rails application servers. You can control which version is installed by editing the manifest file for the Rails application.
rails: configuration: node_version: "12" # will install latest v12.x.x node_version: "12.18" # will install latest v12.18.x node_version: "12.18.3" # will install specific v12.18.3
To apply changes to the Node version you need to update your manifest file, then deploy-with-options and select the Apply Ruby/Node upgrades option.
