The modal system

The modal system is a part of the framework that handles rendering modal dialogs, warnings, and other similar displays. Its main goal is to coordinate modals across different applications so that only a single modal is rendered for the user at a time without any other modals being removed.

To use the modal system, first your application must register the modal as described below. Once the modal is registered, call showModal (see API reference docs) with the modal name and the framework will render the modal for you.

Usage

Implementation of the modal

The ModalHeader and ModalBody should be at the top level of the modal component and wrapped in a React.Fragment.

const ModalComponent = ({ onClose, props }) => {
	return (
		<React.Fragment>
			<ModalHeader closeModal={onClose} >
				{header content goes here}
			</ModalHeader>
 			<ModalBody>
				{modal body goes here}
			</ModalBody>
			<ModalFooter>
				{modal footer goes here}
			</ModalFooter>
		</React.Fragment>
	)
}

Failing to wrap your modal in a React Fragment would cause the modal body to not vertical-scroll properly.

Registering the modal

Register the modal by name in the modals property in routes.json and export it in the index.ts file of the app that defines the modal. The name should be suffixed with -modal. For example, if the modal name is delete-condition, the name should be delete-condition-modal. The component should be the name of the component that renders the modal.

routes.json

"modals": [
	{
	  "name": "your-modal-name",
	  "component": "modalComponentName"
	}
]

index.ts

import { getAsyncLifecycle } from '@openmrs/esm-framework';
 
export const modalComponentName = getAsyncLifecycle(
  () => import('/path-to-the-modal-component/modal-component.tsx'),
  options,
);Triggering the modal

Finally, you can trigger your modal by calling showModal along with all the props you need to pass into the modal. In the example below, we've passed in onClose as a prop to the modal component. The dispose function that is returned by showModal can be called to "dispose" or force close the modal.
