Bootstrapping ​

Bootstrapping is the process of loading the UI5 runtime into the browser. abap2UI5 generates a <script src="…/sap-ui-core.js"> tag in the page <head>; the URL decides which UI5 version is loaded, from which delivery channel (CDN or your own server) and whether the cache-buster is active.

Pick a Bootstrap Source ​

abap
METHOD z2ui5_if_exit~set_config_http_get.

    cs_config-src = `https://ui5.sap.com/1.116.0/resources/sap-ui-core.js`.

ENDMETHOD.

Without an override, abap2UI5 uses the OpenUI5 cache-buster URL — i.e. the latest stable OpenUI5 build.

OpenUI5 vs SAPUI5 ​

  • OpenUI5 (sdk.openui5.org) is the Apache-licensed open-source subset of UI5. It contains all libraries a typical abap2UI5 app uses: sap.m, sap.ui.core, sap.ui.layout, sap.ui.table, sap.ui.unified, sap.uxap, sap.f, sap.tnt, sap.viz.
  • SAPUI5 (ui5.sap.com) is the SAP-licensed superset. It adds e.g. sap.ui.comp (Smart Controls, ValueHelpDialog), sap.suite.ui.commons, sap.ui.generic.app and the Fiori Elements floorplans.

If you only need controls available in OpenUI5 — which covers the vast majority of abap2UI5 apps — stick with sdk.openui5.org. Switch to ui5.sap.com only when you genuinely need a sap.ui.comp.* control or a SAPUI5-only library.

Pinning a Version ​

Hard-coding a version (/1.116.0/) keeps your app stable when SAP ships a new patch. Without a version the CDN serves the current "evergreen" release, which is convenient but can break the app the next time SAP rolls out a change. For productive apps, pin the version explicitly.

Cache-Buster ​

URLs containing sap-ui-cachebuster append a versioned token to every asset URL, so the browser cache is invalidated automatically whenever SAP releases a new build. Use it when you intentionally stay on the latest release.

Local Hosting ​

If your gateway has the UI5 ABAP repository (/sap/public/bc/ui5_ui5/resources/) installed, you can serve UI5 from your own SAP system instead of a CDN. This is faster on the intranet, works offline and avoids any external dependency, but you need a basis admin to keep the UI5 version current. See UI5 Version for the available approaches.
