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.

    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

Applying changes

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.
