ngx-if-else-loading

The *ngxIfElseLoading directive is a drop-in replacement for *ngIf that shows a loading animation while the condition is falsy (i.e. while content is loading).

Installation

To install this library, run:

npm install @ngx-utilities/ngx-if-else-loading --save -or- yarn add @ngx-utilities/ngx-if-else-loading

and then import and export NgxIfElseLoadingModule in your Angular SharedModule:

// shared.module.ts

import { NgxIfElseLoadingModule } from '@ngx-utilities/ngx-if-else-loading';

@NgModule({
  imports: [
    NgxIfElseLoadingModule
  ],
  exports: [
    NgxIfElseLoadingModule
  ]
})
export class SharedModule { }

With a custom loading spinner

You can provide a custom loading component. It can be anything you want, it just has to accept a message input. If your custom loading component is named MyLoadingComponent, the setup will look like this:

// shared.module.ts

@NgModule({
  imports: [
    NgxIfElseLoadingModule.withCustomLoadingComponent(MyLoadingComponent)
  ],
  declarations: [
    MyLoadingComponent
  ],
  entryComponents: [
    MyLoadingComponent
  ]
  exports: [
    NgxIfElseLoadingModule
  ]
})
export class SharedModule { }

Usage

<ng-container *ngxIfElseLoading="items | async; let items">
  ...content
</ng-container>

With a custom message

<ng-container *ngxIfElseLoading="items | async; let items; withMessage 'Loading items...'">
  ...content
</ng-container>
