Installation

ngx-spinner is available via npm and yarn

Using npm:

$ npm install ngx-spinner --save

Using yarn:

$ yarn add ngx-spinner

Using angular-cli:

$ ng add ngx-spinner

Usage

Add css animation files to angular.json config

{
  "styles": [
    "node_modules/ngx-spinner/animations/ball-scale-multiple.css" // ===> Add css file based on your animation name(here it's "ball-scale-multiple")
    // You're able to add multiple files if you need
  ]
}

Import NgxSpinnerModule in in the root module(AppModule):

import { NgModule, CUSTOM_ELEMENTS_SCHEMA } from "@angular/core";
import { BrowserAnimationsModule } from "@angular/platform-browser/animations";
// Import library module
import { NgxSpinnerModule } from "ngx-spinner";

@NgModule({
  imports: [
    // ...
    BrowserAnimationsModule,
    NgxSpinnerModule,
  ],
  schemas: [CUSTOM_ELEMENTS_SCHEMA],
})
export class AppModule {}

NOTE

• There is possibility to use global configuration for NgxSpinnerModule.
• Just call forRoot method for NgxSpinnerModule and pass configuration object.
• The input properties of NgxSpinnerComponent has higher priority than global options

// Available options
interface NgxSpinnerConfig {
  type?: string;
}
// Use in app
@NgModule({
  imports: [
    NgxSpinnerModule.forRoot({ type: 'ball-scale-multiple' })
  ]
})

Add NgxSpinnerService service wherever you want to use the ngx-spinner.

import { NgxSpinnerService } from "ngx-spinner";

class AppComponent implements OnInit {
  constructor(private spinner: NgxSpinnerService) {}

  ngOnInit() {
    /** spinner starts on init */
    this.spinner.show();

    setTimeout(() => {
      /** spinner ends after 5 seconds */
      this.spinner.hide();
    }, 5000);
  }
}

Now use in your template

<ngx-spinner type="ball-scale-multiple"></ngx-spinner>

See Demo

Methods

• NgxSpinnerService.show() Shows the spinner
• NgxSpinnerService.hide() Hides the spinner

Available Options

• [bdColor]: RGBA color format. To set background-color for backdrop, default rgba(51,51,51,0.8) where alpha value(0.8) is opacity of backdrop
• [size]: Anyone from small, default, medium, large. To set size of spinner, default large
• [color]: Any css color format. To set color of spinner, default #fff
• [type]: Choose any animation spinner from Load Awesome. To set type of spinner
• [fullScreen]: true or false To enable/disable fullscreen mode(overlay), default true

Using Spinner Type

<ngx-spinner
  bdColor="rgba(51,51,51,0.8)"
  size="medium"
  color="#fff"
  type="ball-scale-multiple"
>
  <p style="font-size: 20px; color: white">Loading...</p>
</ngx-spinner>

Using Custom Spinner

<ngx-spinner
  bdColor="rgba(0, 0, 0, 1)"
  template="<img src='https://media.giphy.com/media/o8igknyuKs6aY/giphy.gif' />"
>
</ngx-spinner>

NOTE

• You can pass HTML code as loading text now, instead of input parameter(loadingText). Check above code for reference.
• If you want multiple ngx-spinner instance, just add name attribute with ngx-spinner component. But in this case, you've to pass that particular name of a spinner in show/hide method. Check Demo
• You can also change the options/configuration of spinner through service now.
• For smaller bundle size, add specific css file under "styles" array in angular.json file

this.spinner.show("mySpinner", {
  type: "line-scale-party",
  size: "large",
  bdColor: "rgba(0, 0, 0, 1)",
  color: "white",
  template:
    "<img src='https://media.giphy.com/media/o8igknyuKs6aY/giphy.gif' />",
});

How to use type?

• Go to the Load Awesome.
• Select any animation, copy name of animation, replace all spaces with hyphen(-) and all letters should be lowercase.
  • Let's say if I select "Ball 8bits" animation then type will be ball-8bits.
  • For more information you can check it out Demo
  • For smaller bundle size you need to add css for ball-8bits animation(e.g. ball-8bits.css)

Useful Tips

• Make sure you've added CUSTOM_ELEMENTS_SCHEMA as your schema in your main module.
• If you use multiple show() methods in a single component or single function one after another then wrap the show() method within setTimeout() method to avoid any rendering issue.
• When you want to use spinner inside any container(fullScreen: false), in that case your parent element of spinner must have position: relative; style property.
• You can't set custom template through service options, it's a limitation by Angular itself.
