Upgrade NodeJs for Ghost CMS

Upgrading to Node.js v18 for your Ghost CMS can enhance performance and security, but it’s crucial to approach the upgrade process carefully to ensure compatibility and prevent disruptions to your site. Here’s a step-by-step guide to upgrading Node.js for Ghost CMS, assuming you have a basic understanding of using the command line and that your Ghost CMS is self-hosted.

Why Upgrade Ghost to Node.js V18

Upgrading to Node.js v18 for Ghost CMS is an important step for several reasons, especially considering that newer versions of Ghost now require Node.js v18 to function properly. Here are some compelling reasons to upgrade:

Compatibility with Ghost CMS

Ghost has updated its requirements to necessitate Node.js v18 for optimal performance and compatibility. Running your Ghost CMS on an outdated version of Node.js could lead to compatibility issues, preventing you from updating to the latest versions of Ghost. These updates often include new features, performance improvements, and security patches, crucial for maintaining a secure and efficient website.

Improved Performance

Node.js v18 includes performance enhancements that can significantly impact the speed and efficiency of your Ghost CMS. Faster server response times, improved handling of concurrent connections, and reduced latency are just a few of the benefits of these performance improvements. This can lead to a better user experience for your visitors and potentially improve your site’s SEO.

Security Enhancements

Each new release of Node.js includes security updates that protect against vulnerabilities discovered in previous versions. Upgrading to Node.js v18 ensures that your Ghost CMS is safeguarded with the latest security patches. This is critical for protecting your site from potential attacks and data breaches, which can compromise user data and damage your reputation.

Access to New Features

Node.js v18 introduces several new features and improvements that can benefit developers. These include updates to the V8 JavaScript engine, new JavaScript language features, and enhancements to the Node.js standard library. By upgrading, developers can use these new capabilities to improve their custom Ghost themes and integrations’ functionality, efficiency, and maintainability.

Long-Term Support (LTS)

Node.js v18 is a Long-Term Support (LTS) version, which means it will receive critical bug fixes, security updates, and performance improvements for an extended period. This makes v18 a stable and reliable choice for production environments, ensuring that your Ghost CMS runs smoothly and securely for the foreseeable future.

Let’s see how you can upgrade Ghost CMS to Node.js v18 without breaking your website and not losing any content.

Step1: Backup Your Ghost CMS

Before making any changes, it’s essential to back up your Ghost content and configuration. You can do this from the Ghost admin interface:

  1. Log in to your Ghost admin panel (e.g., yourdomain.com/ghost).
  2. Navigate to Settings > Advanced > Import/Export.
  3. Under the “Export your content” section, click on “Export” to download a JSON file of your Ghost content.

Additionally, ensure you have backups of any custom themes or modifications you’ve made.

Step2: Check Node.js Compatibility

Ghost CMS has specific Node.js version requirements. Before upgrading, check the official Ghost support page or the package.json file in your Ghost installation for the supported Node.js versions.

Step3: Upgrade Node.js

For Linux Users

  1. Remove the Old Version (if necessary):
    • First, check your current Node.js version by running node -v.
    • If you need to uninstall an older version, use sudo apt-get remove nodejs (for Debian-based systems) or the appropriate command for your distribution.
  2. Install Node.js v18:
    • The most straightforward method is to use the NodeSource binary distributions. Run the following commands:curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash - sudo apt-get install -y nodejs
    • After installation, verify the version by running node -v.

For macOS Users

Using Homebrew is the most convenient method:

  1. Update Homebrew:brew update
  2. Upgrade Node.js:brew upgrade node
  3. If Node.js isn’t already installed, or if you prefer a fresh installation:brew install node@18
  4. Link Node.js version 18 if necessary:brew link --overwrite node@18
  5. Verify the installation:node -v

For Windows Users

  1. Download the Windows installer for Node.js v18 from the official Node.js website.
  2. Run the installer, following the prompts to upgrade Node.js.
  3. Verify the installation by opening a command prompt and running node -v.

Step4: Update Ghost CMS

After upgrading Node.js, ensure your Ghost CMS is up to date:

  1. Navigate to your Ghost installation directory.
  2. Run ghost update to update Ghost to the latest version. This command also checks for compatibility issues.


  • If you encounter issues after upgrading, consult the Ghost support forum and the Node.js documentation.
  • Compatibility issues with themes or custom code may arise. Test your site thoroughly and update any incompatible code.


Upgrading to Node.js v18 for Ghost CMS can significantly benefit your site’s performance and security. However, always back up your data before proceeding and carefully follow the upgrade steps to avoid potential issues. Remember to check for any compatibility notices from the Ghost development team regarding the Node.js version.
