@sap/hana-client
SAP's own Node.js driver for SAP HANA: connect, run SQL and prepared statements, synchronously, through callbacks or as promises, over native client libraries npm installs per platform.
Reaching SAP HANA from Node.js with no framework database layer in between: a connection is opened with connect, statements run with exec, and prepare returns a statement executed with parameters, the same calls available synchronously, through callbacks, or as promises through the package's own extension/Promise.js module. Connection details are passed to the call or taken from a key in the hdbuserstore, so a host, port and password need not sit in the source. The driver is not JavaScript alone: it contains native libraries, npm downloads the ones for every available platform on install, the Node.js driver shipped with the SAP HANA client is 64-bit only, and that client install carries the same driver for a machine that already has it. In a CAP project it is not what runs unless it is asked for, since @cap-js/hana@cap-js/hanacds-pluginThe HANA database service — the production default, on the same streamlined architecture as the SQLite and PostgreSQL services.sap official, cap uses hdb by default and adding this package to the dependencies takes precedence over that.
