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:

Services / Models

Audit Logging module services and models are generated via generate-proxy command of the ABP CLI. If you need the module's proxies, you can run the following command in the Angular project directory:

abp generate-proxy --module auditLogging

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
  },
};

The Audit Logging module remote URL configuration shown above is optional. If you don't set a URL, the default.url will be used as fallback.

Distributed Events

This module doesn't define any additional distributed event. See the standard distributed events.
