Arc XP CLI 1.2

Release dates

Sandbox and Production - Tuesday, September 9, 2025

Release summary

We’ve introduced new commands in the Arc XP CLI to streamline and simplify workflows for managing blocks and Fusion bundles, reducing manual steps and making deployments more efficient. These commands are designed to be easily incorporated into CI/CD pipelines, enabling automated build and deployment processes.

arcxp themes upload-bundle - Upload Fusion bundles directly to your configured environment. Useful for pushing bundles as part of an automated build step.
arcxp themes upload-and-deploy-bundle - Upload Fusion bundles and immediately deploy them with a specified engine version. Ideal for continuous deployment pipelines, where tested bundles can be automatically promoted to staging or production environments.
arcxp themes fork-block - Copy a block from the Themes repository into your local codebase — either as is or for customization.

Bug fix

Fixed a bug where the arcxp themes site-properties convert-properties command was not accounting for nested properties when converting JSON to .xlsx.

Improvement

Updated the arcxp themes site-properties convert-properties conversion so that site sheets are generated in alphabetical order when converting JSON to .xlsx.

Arc XP CLI 1.1

Release dates

Sandbox and Production - Wednesday, July 23, 2025

Release summary

This release includes the following updates:

As part of the transition away from the legacy UI for managing site properties, the Arc XP CLI now provides a suite of tools to help teams manage theme-settings and blocks.json manually and effectively.

You can now view, export, and convert site properties from the command line:

arcxp themes site-properties print
Print all current site properties stored in Themes Settings directly in the terminal for quick reference. This would be used as a transition from the UI.
arcxp themes site-properties write-local-settings-file
Save the current site properties to a local file. This would be used as a transition from the UI.
arcxp themes site-properties convert-properties
Convert between .json and .xlsx formats:
- Use .xlsx to make edits in Excel (great for non-technical users)
- Convert it back to .json for use in your project

These tools make it easier for developers and non-developers alike to manage site configurations in a structured, version-controlled workflow.

Important

After you transition to the new workflow, using the UI again overwrites your manual changes to blocks.json. Avoid using the legacy interface after transitioning to preserve your work.

For examples and full command documentation, visit the Arc XP CLI documentation. And for more information, see Arc XP CLI: Themes Package.

Automated with CI/CD

To streamline your workflow and reduce risk during deployment, we recommend setting up CI/CD pipelines for your site configuration.

Our Do-It-Yourself CI/CD Deployment Script (for PageBuilder Engine Bundle) guide walks you through integrating CLI commands into your deployment process.
