LeptonX Angular UI

To add LeptonX into your existing projects, follow the steps below.

• Firstly, install @volosoft/abp.ng.theme.lepton-x using the command below.

yarn add @volosoft/abp.ng.theme.lepton-x

• Then, edit angular.json as follows:

Add theme-specific styles into the styles array of the file. Check the Theme Configurations documentation for more information.

Importing a CSS file as an ECMA module is not supported in Angular 14. Therefore, we need to add the styles in the angular.json file.

You can check the release notes of Angular 14 for more information.

• At last, remove ThemeLeptonModule from app.module.ts and shared.module.ts, and import the following modules in app.module.ts

import { HttpErrorComponent, ThemeLeptonXModule } from '@volosoft/abp.ng.theme.lepton-x';
import { SideMenuLayoutModule } from '@volosoft/abp.ng.theme.lepton-x/layouts';

@NgModule({
  // ...
  imports: [
    // ...
    // ThemeLeptonModule.forRoot(), -> remove this line.
    ThemeLeptonXModule.forRoot(),
    SideMenuLayoutModule.forRoot(), // depends on which layout you choose
    // ...
  ],
  // ...
})
export class AppModule {}

Note: If you are using Resource Owner Password Flow for authorization, you should import the following module as well to app.module.ts:

import { AccountLayoutModule } from '@volosoft/abp.ng.theme.lepton-x/account';

@NgModule({
  // ...
  imports: [
    // ...
    AccountLayoutModule.forRoot({
      layout: {
        authLayoutImg: '/assets/images/login-bg.jpg',
      },
    }),
    // ...
  ],
  // ...
})
export class AppModule {}

authLayoutImg: (Optional) If not given, a default image will be placed on the authentication pages.

• At this point, LeptonX theme should be up and running within your application. However, you may need to overwrite some css variables based your needs for every theme available as follows:

:root {
  .lpx-theme-dark {
    --lpx-logo: url('/assets/images/logo/logo-light.svg');
    --lpx-logo-icon: url('/assets/images/logo/logo-light-icon.svg');
    --lpx-brand: #edae53;
  }

  .lpx-theme-dim {
    --lpx-logo: url('/assets/images/logo/logo-light.svg');
    --lpx-logo-icon: url('/assets/images/logo/logo-light-icon.svg');
    --lpx-brand: #f15835;
  }

  .lpx-theme-light {
    --lpx-logo: url('/assets/images/logo/logo-dark.svg');
    --lpx-logo-icon: url('/assets/images/logo/logo-dark-icon.svg');
    --lpx-brand: #69aada;
  }
}

If everything is ok, you can remove the @volo/abp.ng.theme.lepton in package.json

Customization

Layouts

The Angular version of LeptonX provides layout components for your user interface on ABP Framework Theming. You can use layouts to organize your user interface. You can replace the layout components and some parts of the layout components with the ABP replaceable component system.

The main responsibility of a theme is to provide the layouts. There are three pre-defined layouts that must be implemented by all the themes:

• ApplicationLayoutComponent: The default layout which is used by the main application pages.

• AccountLayoutComponent: Mostly used by the account module for login, register, forgot password... pages.

• EmptyLayoutComponent: The Minimal layout that has no layout components at all.

The Layout components and all the replacable components are predefined in eThemeLeptonXComponents as enum.

How to replace a component

import { ReplaceableComponentsService } from '@abp/ng.core'; // imported ReplaceableComponentsService
import {eThemeLeptonXComponents} from "@volosoft/abp.ng.theme.lepton-x"; // imported eThemeLeptonXComponents enum
//...
@Component(/* component metadata */)
export class AppComponent {
  constructor(
    private replaceableComponents: ReplaceableComponentsService, // injected the service
  ) {
    this.replaceableComponents.add({
      component: YourNewApplicationLayoutComponent,
      key: eThemeLeptonXComponents.ApplicationLayout,
    });
  }
}

See the Component Replacement documentation for more information on how to replace components.

Brand Component

The brand component is a simple component that can be used to display your brand. It contains a logo and a company name. You can change the logo with css but if you want to change logo component, the key is eThemeLeptonXComponents.Logo

///...

  key: eThemeLeptonXComponents.Logo,
});

Breadcrumb Component

On websites that have a lot of pages, breadcrumb navigation can greatly enhance the way users find their way around. In terms of usability, breadcrumbs reduce the number of actions a website visitor needs to take in order to get to a higher-level page, and they improve the findability of website sections and pages.

///...
this.replaceableComponents.add({
  component: YourNewBreadCrumbComponent,
  key: eThemeLeptonXComponents.Breadcrumb,
});

Constant footerLinks are on the right side of the footer.

};
