You may look at: https://www.jqwidgets.com/angular-components-documentation/documentation/angular-cli/angular-cli.htm. It shows how to use jqwidgets-framework or jqwidgets-scripts. let jqx = require …. is not correct according to me. The jqwidgets-framework npm package installs exactly the same files as the .zip archive. The jqwidgets-scripts package contains only scripts without demos and documentation and is smaller package.
