Generator Module

Generator Module serve as a foundational setup tool for initializing projects. They are specifically designed to define and manage services that generate test data or essential initial data at the beginning of a project.

​
Role and Permission Generator Service

The Role and Permission Generator Service comes as a default part of the Generator Module. This means that it’s already set up and ready to use when you start a new project.
Primary Role: To automatically create default roles and permissions within your application.

​
Using createRoleAndPermission Method

In this example, YourCustomPermissionArray, YourPermissionType, and YourRoleAlias are placeholders for your specific permission array, type, and role alias, respectively. 
// Example usage within your application
await this.rolePermissionGeneratorService.createRoleAndPermission({
  permission: YourCustomPermissionArray,
  type: YourPermissionType,
  roleAlias: YourRoleAlias,
  title: "Custom Role Title",
});

​
Implementation in AppModule

In the AppModule, the Role and Permission Generator Service is defined as follows: 
// In AppModule
export class AppModule implements OnModuleInit {
  constructor(
    private readonly rolePermissionGeneratorService: RolePermissionGeneratorService
  ) {}
  async onModuleInit() {
    console.log("Initializing Generator Services...");
    await this.rolePermissionGeneratorService.createDefaultRoleAndPermissions();
  }
}

​
Triggering Generation with a Boolean

The generation process is controlled by a boolean flag. The createDefaultRoleAndPermissions method uses this flag to determine whether to generate roles and permissions. Set generateRolesAndPermission to true to activate the generation each time the application starts. 
// In RolePermissionGeneratorService
async createDefaultRoleAndPermissions(): Promise<void> {
  const generateRolesAndPermission = true; // Set to true to generate roles and permissions
  // ... rest of the method
}
