##### ngx-modialog @ 3.x.x

## Quick start



**In your application root module definition add `ModalModule` and the plugin you want to use:**



We will use the bootstrap plugin (`BootstrapModalModule`) for this introduction.



```typescript

import { ModalModule } from 'ngx-modialog';

import { BootstrapModalModule } from 'ngx-modialog/plugins/bootstrap';



// lots of code...



@NgModule({

  bootstrap: [ /* ... */ ],

  declarations: [ /* ... */ ],

  imports: [

    /* ... */

    ModalModule.forRoot(),

    BootstrapModalModule

  ],

})

export class AppModule { /* lots of code... */ }

```



**In any angular component or service inject the `Modal` service and open a modal**:



```typescript

import { Component, ViewContainerRef } from '@angular/core';

import { Overlay } from 'ngx-modialog';

import { Modal } from 'ngx-modialog/plugins/bootstrap';



@Component({

  selector: 'my-app',

  template: `Alert`

})

export class AppComponent {

  constructor(public modal: Modal) { }



  onClick() {

    const dialogRef = this.modal.alert()

        .size('lg')

        .showClose(true)

        .title('A simple Alert style modal window')

        .body(`

            
Alert is a classic (title/body/footer) 1 button modal window that 

            does not block.


            Configuration:

            
    

                    
  • Non blocking (click anywhere outside to dismiss)
    • 

                    
  • Size large
    • 

                    
  • Dismissed with default keyboard key (ESC)
    • 

                    
  • Close wth button click
    • 

                    
  • HTML content
    • 

                
`)

        .open();



    dialogRef.result

        .then( result => alert(`The result is: ${result}`) );

  }

}

```



If you are using **ngx-modialog** version 3.X.X or below, `open()` returned a promise so replace the last 2 lines with:

```typescript

   dialogRef

       .then( dialogRef => {

           dialogRef.result.then( result => alert(`The result is: ${result}`);

       });

```



We are using the `alert()` method, one of 3 (prompt, confirm)) fluent-api methods we call `drop-ins`



We then use the `result` property to wait for the modal closing event.



**Notes:**

  - Fluent API methods (drop-ins) are pre-configured (presets) methods that allow easy configuration and execution, you can create custom presets - see the demo application.

  - For more control use the `open()` method, which is used by all drop in's internally.

  - We import the `Modal` service from the plugin and not from the root library.

  Import from the root should work but being explicit allow using multiple plugins.



## Demo App

The Demo application is a full implementation of the library with the native plugins.



View it at [shlomiassaf.github.io/ngx-modialog](http://shlomiassaf.github.io/ngx-modialog/)



The demo application is [part of this repository](https://github.com/shlomiassaf/ngx-modialog/tree/master/src/demo/app) and it is a great place to learn by example.



#### Bootstrap / VEX features:

  - Customizable with components, Presets and more...  

  - Select cancel/quit key.

  - Cascading modals.  

  - Element blocking.  

  - Blocking / Non blocking modal.  

  - Modal as a component, replace the content by supplying a custom component.   



The demo application comes with a [dynamic modal generator](http://shlomiassaf.github.io/ngx-modialog#/bootstrap-demo/customizeModals) for the **Boostrap** plugin



## Plugins

Plugins serve as a concrete UI implementation for a modal.



It can be an implementation for a known library (e.g: bootstrap) or something completely unique



While `ngx-modialog` has some built in plugins it is also possible to use external plugins from NPM, if someone decide to build one.



> Built a plugin? I would love to know :)



# Known bugs

### The dialog closes when removing the target DOM element in a click event

ref [issue#111](https://github.com/shlomiassaf/ngx-modialog/issues/111)



To avoid this problem use `event.stopPropagation();` or put the element removal inside a `setTimeout` call

# HELP WANTED!



As a sole author I find it difficult to maintain multiple open source projects.

As a result it is hard for me to replay rapidly to requests/help/etc...



If you would like to contribute, please contact me, the community will thank you.



You can contribute via:



  - Implementing features & Bug fixes

  - Documentation (Extremely important)

  - Issue management



Thank you!
