angular-busy2 Live Demo
Show busy/loading indicators on Observable, Subscription, Promise, Boolean, Number
For AngularJS 1 branch 1.x
Getting Started
Install with npm.
npm install angular-busy2 --save
Add CgBusyModule
as a module dependency for your module.
You have to import it with forRoot
in any module where you want to provide CgBusyDefaults
.
Usually you do that in your root module (app.module
).
If you never import it with forRoot
CgBusyDefaults
will always be undefined
.
forRoot
takes optional CgBusyOptions
as parameter.
For every omitted option in the supplied CgBusyOptions
the libraries default value will be used.
import { CgBusyModule } from 'angular-busy2';
@NgModule({
imports: [
CgBusyModule.forRoot({
backdrop: true
}) //import it with .forRoot in your root module. provide some optional Options.
]
})
In every shared module/sub module you should import CgBusyModule
without forRoot
unless you want to provide a
different instance of CgBusyDefaults
Standalone import directive
import { CgBusyDirective } from 'angular-busy2';
@Component({
standalone: true,
imports: [CgBusyDirective],
// ...
})
// main.ts if you bootstrap application
bootstrapApplication(AppComponent, {
providers: [
importProvidersFrom(CgBusyModule.forRoot())
// ...
]
}).catch(err => console.log(err));
Options
The [cgBusy]
directive expects any Observable, Subscription, Promise, Boolean, Number and optional [cgBusyConfig]
configuration object.
In other words. You may do this:
<div [cgBusy]="promise"></div>
or this:
<div [cgBusy]="promise"
[cgBusyConfig]="{templateRef: customTemplate, message:message, backdrop:backdrop, delay:delay, minDuration:minDuration}"></div>
promise
- Required. The promise/Observables (or array of promises/Observables) that will cause the busy indicator to show. Also supports boolean and numbers (truthy values will show loading...)message
- Optional. Defaults to 'Please Wait...'. The message to show in the indicator. This value may be updated while the promise is active. The indicator will reflect the updated values as they're changed.backdrop
- Optional. Boolean, default is true. If true a faded backdrop will be shown behind the progress indicator.templateRef
- Optional. If provided, the given template will be shown in place of the default progress indicator template.delay
- Optional. The amount of time to wait until showing the indicator. Defaults to 0. Specified in milliseconds.minDuration
- Optional. The amount of time to keep the indicator showing even if the promise was resolved quicker. Defaults to 0. Specified in milliseconds.wrapperClass
- Optional. The name(s) of the CSS classes to be applied to the wrapper element of the busy sign/animation. Defaults toundefined
. Typically only useful if you wish to apply different positioning to the animation.
Overriding Defaults
The default values for message
, backdrop
, templateRef
, delay
, and minDuration
may all be overridden by
overriding the CgBusyDefaults
, like so:
import { CgBusyDefaults } from 'angular-busy2';
class AppComponent {
@ViewChild('customTemplate')
private customTemplateTpl: TemplateRef<any>;
constructor(private busyDefaults: CgBusyDefaults) {
this.busyDefaults.delay = 5000;
}
ngOnInit() {
this.busyDefaults.templateRef = this.customTemplateTpl;
}
}
<ng-template #customTemplate let-options="options">
<div class="custom-template">
<div class="custom-message" [innerHtml]="options.message"></div>
</div>
</ng-template>
Only the values you'd like overridden need to be specified.
