DataModel class

Represents a lazy-loading data model for an xpm package.

Signature

export declare class DataModel

Remarks

This class prepares substitution variables, creates the Liquid engine, and exposes actions and build configurations defined in the package.

The package processor serves as the top-level coordinator for all Liquid-based template processing in an xpm package. It establishes the foundation for variable substitution throughout the package hierarchy:

1. Initializes base substitution variables (platform detection, system information, etc.).
2. Adds package-specific variables from package.json metadata.
3. Merges user-defined properties from xpack.properties.
4. Creates package-level actions accessible across all contexts.
5. Creates build configurations, each inheriting the base substitution context and adding configuration-specific variables.

This hierarchical structure ensures that templates at any level have access to appropriate variables while maintaining clear scoping rules. Package-level actions are available globally, while configuration-level actions are scoped to their respective configurations.
