OData shims for Node.js and Steampunk
Run locally with NodeJS 16+, npm install && npm test
Scaffolding of IF_HTTP_EXTENSION and IF_HTTP_SERVICE_EXTENSION must be implemented separately on the target system by calling ZCL_OAO_HTTP_HANDLER methods.
Services are registered by name before the first request, the same way SEGW registration does it on a real system:
zcl_oao_registry=>register(
iv_service = 'ZSEGW_SRV'
iv_mpc = 'ZCL_ZSEGW_MPC_EXT'
iv_dpc = 'ZCL_ZSEGW_DPC_EXT' ).ZCL_OAO_HTTP_HANDLER resolves /sap/opu/odata/sap/<service>/... through the registry and instantiates the classes dynamically, so the shim can be consumed as a transpiler lib without any concrete service class in it. See test/start.mjs for the Node.js side of the registration.
