ngx-modal-ease is a versatile Angular library providing a lightweight, simple, and performant modal. This library supports data communication between components, opening of multiple modals, custom animations, and a range of customisable options.
Support Angular version starts at v17.
Live demonstration of the ngx-modal-ease library here.
You can install the library using the following command:
npm i ngx-modal-ease
The modal supports a range of customisable options:
Options {
modal?: {
enter?: string;
leave?: string;
top?: string;
left?: string;
};
overlay?: {
enter?: string;
leave?: string;
backgroundColor?: string;
};
size?: {
height?: string;
maxHeight?: string;
width?: string;
maxWidth?: string;
padding?: string;
};
actions?: {
escape?: boolean;
click?: boolean;
};
data?: {
[key: string]: unknown;
};
}
| Name | Default | Description |
|---|---|---|
| enter | Define the enter animation for the modal or the overlay respecting the shorthand animation property. | |
| leave | Define the leave animation for the modal or the overlay respecting the shorthand animation property. | |
| top | 50 | Top position of the modal in percent. Can be defined in any measure unit. |
| left | 50 | Left position of the modal in percent. Can be defined in any measure unit. |
| backgroundColor | rgba(0, 0, 0, 0.4); | Background color of the overlay. Can be defined in any color notation (rgba, hex, hsl, ...). |
| minHeight | Minimum height of the modal. Can be defined in any measure unit. | |
| height | Height of the modal. Can be defined in any measure unit. | |
| width | Width of the modal. Can be defined in any measure unit. | |
| maxWidth | 100 | Max width of the modal in percent. Can be defined in any measure unit. |
| padding | 0.5 | Padding to be applied on the modal in rem. Can be defined in any measure unit. |
| escape | true | Enable escape to close the current modal. |
| click | true | Enable click outside of the modal to close the current modal. |
| data | Data communication between components under the form of key-value pairs. Any type of data is supported. |
Inject the ModalService through regular dependency injection in your component.
In the following example, ModalContentComponent is the content of the modal and should be provided as first parameter. As second parameter, provide an object respecting the Options interface (see above).
this.modalService.open(ModalContentComponent, {
modal: {
<!-- animation -->
enter: 'enter-scale-down 0.1s ease-out',
},
overlay: {
<!-- animation -->
leave: 'fade-out 0.3s',
},
size: {
<!-- modal configuration -->
width: '400px',
},
data: {
<!-- data to ModalContentComponent -->
type: 'Angular modal library',
},
})
.subscribe((dataFromModalContentComponent) => {
...
});
Any type of data can be provided between components. Create the corresponding property (here, type) in your component (here, ModalContentComponent) and the property will be assigned with the provided value.
In your ModalContentComponent:
To pass information from the ModalContentComponent to your current component, inject the ModalService through regular dependency injection and call the close(data) method from the service with any data you wish to send back to your component. This method returns an RxJs subject, so subscribe to it as shown in the above example. It is not necessary to unsubscribe from the subscription since it will automatically complete() in the service.
<!-- Inside ModalContentComponent -->
onClose() {
this.modalService.close(this.dataToSendBack);
}
Publicly available methods have been exhaustively documented and typed, so you should get autocomplete and help from your code editor. Press on CTRL + space to get help on the available properties in the Options object.
This library exposes a ModalService that contains the following API:
<!-- Opens a component inside the modal -->
open<C>(componentToCreate: Type<C>, options?: Options);
<!-- Close a modal with optional data to send back -->
close(data?: unknown);
<!-- Close all opened modals -->
closeAll();
NB: Z-index of overlay and modal start at 1000 and 2000 respectively. In case of multiple modals, z-indexes will be incremented by 1000.
This library comes with predefined and ready-to-use animations keyframes. Just fill in the name, duration and easing function (more info on the animation CSS shorthand here). Those animations are position agnostic, so if you wish to position your modal at other top and left values than default, it will correctly work. Of course, you can create your own keyframes too.
/* Recommended: 0.2s ease-out */

If you create your own keyframes, I would recommend to create a new file modal-animations (.css or preprocessor), and @import it in your styles.css (or preprocessor) at the root of the application.
This library supports Server Side Rendering (SSR). The modal will not instantiate during server-side execution, as it requires access to the DOM API.
This library has been documented and should provide autocomplete and help from your code editor. Tested on VS Code.
Emphasis has been placed on performance, adopting ChangeDetectionStrategy.OnPush strategy. This library respects Angular's mindset and use the Angular API to create components. Modal components will be removed from the DOM after closing.
Version 0.0.4: Fixed of a communication bug between components. Every modal has now its own subject to send back data to the calling component. Version 0.0.5: Fixed a bug between components that prevented the component from closing when applying different animations with multiple stacked modals.
Please provide a detailed description of the encountered bug, including your options and the steps/actions that led to the issue. An accurate description will help me to reproduce the issue.
