*This project offers a pure ABAP approach for developing UI5 apps, eliminating the need for JavaScript, OData and RAP — similar to the past, when only a few lines of ABAP sufficed to display inputs and tables through Selection Screens and ALVs. Designed with a minimal system footprint, it works in both on-premise and cloud environments.* #### Key Features * **User-Friendly:** Implement just one interface for a standalone UI5 application * **100% ABAP:** Develop using pure ABAP (no JavaScript, DDL, EML or Customizing) * **Minimal System Footprint:** Based on a plain HTTP handler (no BSP, OData, CDS, BOPF or RAP) * **Cloud and On-Premise Ready:** Works with both language versions (ABAP for Cloud, Standard ABAP) * **Broad System Compatibility:** Compatible with all ABAP releases (from NW 7.02 to ABAP 2311) * **Easy Installation:** abapGit project, no additional app deployment required #### Compatibility * BTP ABAP Environment (ABAP for Cloud) * S/4 Public Cloud ABAP Environment (ABAP for Cloud) * S/4 Private Cloud or On-Premise (ABAP for Cloud, Standard ABAP) * R/3 NetWeaver AS ABAP 7.50 or higher (Standard ABAP) * R/3 NetWeaver AS ABAP 7.02 to 7.42 - use the [downport repository](https://github.com/abap2UI5/abap2UI5-downport) #### Information (Blog Series) 1.

DATA(lv_resp) = SWITCH #( server->request->get_method( ) WHEN 'GET' THEN z2ui5_cl_fw_http_handler=>http_get( ) WHEN 'POST' THEN z2ui5_cl_fw_http_handler=>http_post( server->request->get_cdata( ) ) ). server->response->set_header_field( name = `cache-control` value = `no-cache` ). server->response->set_cdata( lv_resp ). server->response->set_status( code = 200 reason = `success` ). ENDMETHOD. ``` ##### ABAP for Cloud :cloud: ```abap METHOD if_http_service_extension~handle_request. DATA(lv_resp) = SWITCH #( request->get_method( ) WHEN 'GET' THEN z2ui5_cl_fw_http_handler=>http_get( ) WHEN 'POST' THEN z2ui5_cl_fw_http_handler=>http_post( request->get_text( ) ) ). response->set_header_field( i_name = `cache-control` i_value = `no-cache` ). response->set_text( lv_resp ). response->set_status( 200 ). ENDMETHOD. ``` #### Usage Develop UI5 Apps by implementing the abap2UI5 interface: ```abap CLASS z2ui5_cl_app_hello_world DEFINITION PUBLIC. PUBLIC SECTION. INTERFACES z2ui5_if_app. DATA quantity TYPE string. ENDCLASS. CLASS z2ui5_cl_app_hello_world IMPLEMENTATION. METHOD z2ui5_if_app~main. CASE client->get( )-event. WHEN 'BUTTON_POST'. client->message_toast_display( |{ product } { quantity } - send to the server| ). ENDCASE. client->view_display( z2ui5_cl_xml_view=>factory( client )->page( 'abap2UI5 - Hello World App' )->simple_form( )->content( ns = `form` )->title( 'Input here and send it to the server...' )->label( 'Product-001' )->input( client->_bind_edit( quantity ) )->button( text = 'post' press = client->_event( 'BUTTON_POST' ) )->stringify( ) ). ENDMETHOD. ENDCLASS. ``` #### FAQ * Check out the [documentation](https://github.com/abap2UI5/abap2UI5-documentation/) for installation & configuration guidelines * Still have open questions?
