In Angular, there isn’t a built-in feature like Spring Boot’s banner.txt generator for displaying a custom banner in the console. However, we can achieve a similar effect by creating a custom script that logs a banner message when our application starts.

Steps to Create a Console Banner in Angular

1. Create a Banner Service:
   Let´s create a service that logs our banner message to the console.

   // src/app/services/banner.service.ts
   import { Injectable } from '@angular/core';

   @Injectable({
       providedIn: 'root'
   })
   export class BannerService {
       constructor() {
           this.logBanner();
       }

       private logBanner() {
           console.log(`
           ****************************************
           *        My Angular App                *
           *        Version: 1.0.0                *
           ****************************************
           `);
       }
   }

2. Inject the Service in App Module:
   Make sure to include this service in our application. We can do this in our AppModule.

   // src/app/app.module.ts
   import { NgModule } from '@angular/core';
   import { BrowserModule } from '@angular/platform-browser';
   import { AppComponent } from './app.component';
   import { BannerService } from './services/banner.service';

   @NgModule({
       declarations: [
           AppComponent
       ],
       imports: [
           BrowserModule
       ],
       providers: [BannerService],
       bootstrap: [AppComponent]
   })
   export class AppModule { }

3. Run our Application:
   When we run our Angular application, the banner will be displayed in the console.

Customization

We can customize the banner message, including dynamic data like the version number or other relevant information. This approach gives us flexibility similar to Spring Boot’s banner.txt.

Conclusion

While Angular doesn’t have a built-in console banner feature, we can easily create one using a service that logs our desired message when the application initializes. This method allows for a clean and organized way to display important information in the console.
