Edit Preview

Skill for managing temporary Lightdash preview environments to test semantic layer changes in isolation.

Purpose

Enables the "Semantic Layer Developer" to create safe, isolated environments for stakeholders to review changes and for automated validation before production deployment.

Commands

• •lightdash preview: Creates a temporary project with the current local state.
• •lightdash stop-preview: Tiers down a specific preview environment.

Behavior

1. •Environment Creation: Run lightdash preview after local compilation is successful.
2. •Naming Convention: ALWAYS use the --name flag to provide a descriptive name for the preview (e.g., feature-revenue-calc). This allows for consistent tracking and cleanup.
3. •Iterative Development: Changes pushed to an existing preview name will update that environment.
4. •Cleanup: Run lightdash stop-preview once testing is complete to free up resources and keep the workspace organized.
