stop closing the modal by clicking backdrop or outside the modal

As per the answer of @anshuVersatile, I understand we need to use some modal options.

Then I create a object of NgbModalOptions and pass it as second parameter of my open method and it works.

Code is as follows :

let ngbModalOptions: NgbModalOptions = {      backdrop : 'static',      keyboard : false};console.log(ngbModalOptions);const modalRef = this.modalService.open(NgbdModalContent, ngbModalOptions);

Here is the updated plunker.

Though it is late still it might be helpful for somebody else facing the issue:

 const config: ModalOptions = {                backdrop: 'static',                keyboard: false,                animated: true,                ignoreBackdropClick: true,                initialState: {                  data1: 'new-user',                  username: 'test'                }              };              this.bsModalRef = this.modalService.show(MyComponent, config);

initialState object is used to pass data to modal.

$modal.open({   // ... other options   backdrop  : 'static',   keyboard  : false});

While you creating your modal you can specify its behavior:
