Install ng-wizard through npm:

$ npm install --save ng-wizard

Include bootstrap CSS file (skip if already imported):

@import '~bootstrap/dist/css/bootstrap.min.css';

Include ng-wizard CSS files:

/* Mandatory */
@import '~ng-wizard/themes/ng_wizard.min.css';

/* Optional */
/* If a theme other than default is used, the css file for that theme is required. */
@import '~ng-wizard/themes/ng_wizard_theme_arrows.min.css';
@import '~ng-wizard/themes/ng_wizard_theme_circles.min.css';
@import '~ng-wizard/themes/ng_wizard_theme_dots.min.css';

Import the ng-wizard module into your apps module:

import { NgModule } from '@angular/core';

import { NgWizardModule, NgWizardConfig, THEME } from 'ng-wizard';

const ngWizardConfig: NgWizardConfig = {
  theme: THEME.default
};

@NgModule({
  imports: [
    NgWizardModule.forRoot(ngWizardConfig)
  ]
})
export class AppModule { }

Add an ng-wizard component to the html template of your component:

<ng-wizard [config]="config" (stepChanged)="stepChanged($event)">
  
  <ng-wizard-step [title]="'Step 1'" [description]="'Step 1 description'"
    [canEnter]="isValidTypeBoolean" [canExit]="isValidFunctionReturnsBoolean.bind(this)">
    <span>Step 1 content</span>
  </ng-wizard-step>
  
  <ng-wizard-step [title]="'Step 2'" [description]="'Step 2 description'" [state]="stepStates.disabled">
    <span>Step 2 content</span>
  </ng-wizard-step>
  
  <ng-wizard-step [title]="'Step 3'" [description]="'Step 3 description'"
    [canEnter]="isValidFunctionReturnsObservable.bind(this)" [canExit]="isValidFunctionReturnsBoolean.bind(this)">
    <span>Step 3 content</span>
  </ng-wizard-step>

<ng-wizard-step [title]="'Step 4'" [description]="'Step 4 description'">
    <span>Step 4 content</span>
  </ng-wizard-step>

  <ng-wizard-step [title]="'Step 5'" [description]="'Step 5 description'" [state]="stepStates.hidden">
    <span>Step 5 content</span>
  </ng-wizard-step>
  
  <ng-wizard-step [title]="'Step 6'" [description]="'Step 6 description'" [state]="stepStates.error">
    <span>Step 6 content</span>
  </ng-wizard-step>
  
  <ng-wizard-step [title]="'Step 7'" [description]="'Step 7 description'">
    <span>Step 7 content</span>
  </ng-wizard-step>
</ng-wizard>

[config] is an optional parameter for ng-wizard component.

If you want to override ng-wizard default configuration defined in apps module for a specific component, define [config] parameter in your ***.component.ts file.

import { Component, OnInit } from '@angular/core';
import { of } from 'rxjs';
import { NgWizardConfig, NgWizardService, StepChangedArgs, StepValidationArgs, STEP_STATE, THEME } from 'ng-wizard';

@Component({
  templateUrl: 'app.component.html'
})
export class AppComponent implements OnInit {
  stepStates = {
    normal: STEP_STATE.normal,
    disabled: STEP_STATE.disabled,
    error: STEP_STATE.error,
    hidden: STEP_STATE.hidden
  };

  config: NgWizardConfig = {
    selected: 0,
    theme: THEME.arrows,
    toolbarSettings: {
      toolbarExtraButtons: [
        { text: 'Finish', class: 'btn btn-info', event: () => { alert("Finished!!!"); } }
      ],
    }
  };

  constructor(private ngWizardService: NgWizardService) {
  }

  ngOnInit() {
  }

  showPreviousStep(event?: Event) {
    this.ngWizardService.previous();
  }

  showNextStep(event?: Event) {
    this.ngWizardService.next();
  }

  resetWizard(event?: Event) {
    this.ngWizardService.reset();
  }

  setTheme(theme: THEME) {
    this.ngWizardService.theme(theme);
  }

  stepChanged(args: StepChangedArgs) {
    console.log(args.step);
  }

  isValidTypeBoolean: boolean = true;

  isValidFunctionReturnsBoolean(args: StepValidationArgs) {
    return true;
  }

  isValidFunctionReturnsObservable(args: StepValidationArgs) {
    return of(true);
  }
}
