Usage

Import NgxLoadingXModule into the root of your module

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { CoreModule } from './core/core.module';
import { NgxLoadingXModule } from 'ngx-loading-x';
 
@NgModule({
  declarations: [AppComponent],
  imports: [
    BrowserModule,
    // Import NgxLoadingXModule
    NgxLoadingXModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

create a boolean variable that is accessible from the component which will contain ngx-loading-x. This boolean is used as an input into ngx-loading to determine when the loading spinner is visible.

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

@Component({
    //...
})
export class AppComponent implements OnInit {
    //...
    public loading = false;

    constructor() { }

    ngOnInit() { }

    registerTest() {
        // loading triggered
        this.load = true;

        setTimeout(() => {
            // loader stops after 5s
            this.load = false,
            // ..
            this.register = true;
        }, 5000)
    }
}

Include ngx-loading-x component selector to your app component templates, Set the [show] input variable of ngx-loading-x to point to your boolean i.e load, which will determine the ngx-loading-x visibility.

<ngx-loading-x [show]="load"></ngx-loading-x>
