I've inherited a project that references sapui5 libraries as a remote resource:
<script src="https://sapui5.hana.ondemand.com/1.84.31/test-resources/sap/ushell/bootstrap/sandbox.js"></script>
<script src="https://sapui5.hana.ondemand.com/1.84.31/resources/sap-ui-core.js"></script>
Occasionally, our corporate network fails to download some of the js files of the SAPUI5 framework (net::ERR_HTTP2_PROTOCOL_ERROR errors or takes half a minutes for each js file). As a workaround, i would like to reference the SAPUI5 framework JS libraries locally. It appears that there is no way to download just the JS framework files (similar to JQuery). I would have to examine the browser requests and manually save the JS files locally.
Is there a better way ?
If you use the UI5 Build tooling it will give you the opportunity the create self-contained packages that include all used UI5 libraries.
