Installation

In order to configure the application to use the AuditLoggingModule, you first need to import AuditLoggingConfigModule from @volo/abp.ng.audit-logging/config to root module. AuditLoggingConfigModule has a static forRoot method which you should call for a proper configuration.

// app.module.ts
import { AuditLoggingConfigModule } from '@volo/abp.ng.audit-logging/config';

@NgModule({
  imports: [
    // other imports
    AuditLoggingConfigModule.forRoot(),
    // other imports
  ],
  // ...
})
export class AppModule {}

The AuditLoggingModule should be imported and lazy-loaded in your routing module. It has a static forLazy method for configuration. Available options are listed below. It is available for import from @volo/abp.ng.audit-logging.

// app-routing.module.ts
const routes: Routes = [
  // other route definitions
  {
    path: 'audit-logs',
    loadChildren: () =>
      import('@volo/abp.ng.audit-logging').then(m => m.AuditLoggingModule.forLazy(/* options here */)),
  },
];

@NgModule(/* AppRoutingModule metadata */)
export class AppRoutingModule {}

If you have generated your project via the startup template, you do not have to do anything, because it already has both AuditLoggingConfigModule and AuditLoggingModule.

Options

You can modify the look and behavior of the module pages by passing the following options to AuditLoggingModule.forLazy static method:

• entityActionContributors: Changes grid actions. Please check Entity Action Extensions for Angular for details.
• toolbarActionContributors: Changes page toolbar. Please check Page Toolbar Extensions for Angular for details.
• entityPropContributors: Changes table columns. Please check Data Table Column Extensions for Angular for details.

Services

The @volo/abp.ng.audit-logging package exports the following services which cover HTTP requests to counterpart APIs:

• AuditLoggingService: Covers several methods that performing HTTP calls for Audit Logs page.
• EntityChangeService: Covers several methods that performing HTTP calls for Entity Changes tab in Audit Logs page.

AuditLoggingModule Replaceable Components

eAuditLoggingComponents enum provides all replaceable component keys. It is available for import from @volo/abp.ng.audit-logging.

Please check Component Replacement document for details.

Remote Endpoint URL

The Audit Logging module remote endpoint URL can be configured in the environment files.

export const environment = {
  // other configurations
  apis: {
    default: {
      url: 'default url here',
    },
    AbpAuditLogging: {
      url: 'Audit Logging remote url here'
    }
    // other api configurations
  },
};
