ajson

abap2UI5 handles all frontend-backend communication through JSON. Initially, the framework used SAP's /UI2/CL_JSON, but this approach proved problematic: critical functionality varied across releases, documentation was sparse, and compatibility issues emerged frequently.

The solution: ajson, a robust open-source JSON library that improved abap2UI5's functionality significantly.

Why ajson?

• Zero SAP API Dependencies - Eliminates reliance on release-specific SAP classes
• Universal Compatibility - Works seamlessly from NW 7.02 to ABAP Cloud
• Developer-Friendly - Intuitive API with comprehensive documentation
• Active Maintenance - Responsive issue resolution and continuous improvements

Integration

ajson integrates directly into the z2ui5 namespace and installs automatically with abap2UI5. Access it anywhere in your code:

DATA(input) = z2ui5_cl_ajson=>parse( json_string ).

DATA(output) = z2ui5_cl_ajson=>create_empty( )->set( 
  iv_path = '/name' 
  iv_val  = 'value' 
)->stringify( ).

Automatic Updates

Every ajson update and bug fix flows automatically into abap2UI5 via GitHub Actions and the mirror-ajson repository. You're always running the latest stable version without manual intervention.
