Setting your Node version
Controlling the Node version for your Rails application
We automatically install the latest release of Node version 6.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: "6" # will install latest v6.x.x node_version: "6.14" # will install latest v6.14.x node_version: "6.14.4" # will install specific v6.14.4
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.
