  Hi,

  You can consider using distributed cache to store the dynamic menus.

  For example:

  public class MyMenuContributor : IMenuContributor
  {
      private readonly IDistributedCache<DynamicMenusCacheItem> _menusCache;
       
      public MyMenuContributor(IConfiguration configuration)
      {
          _configuration = configuration;
      }
  
      public async Task ConfigureMenuAsync(MenuConfigurationContext context)
      {
          if (context.Menu.Name == StandardMenus.Main)
          {
              await ConfigureMainMenuAsync(context);
          }
      }
  
      private Task ConfigureMainMenuAsync(MenuConfigurationContext context)
      {
          var dynamicMenus = await _menusCache.GetOrAddAsync(
                  nameof(DynamicMenusCacheItem), //Cache key
                  async () => await GetFromRemoteAPI(),
                  () => new DistributedCacheEntryOptions
                  {
                      AbsoluteExpiration = DateTimeOffset.Now.AddHours(1)
                  }
              );
              
          //...
      }
      
      private Task<DynamicMenusCacheItem> GetFromRemoteAPI()
      {
          //...
      }
  }
  
  public class DynamicMenusCacheItem
  {
     ....
  }

  Hi, And also how can I trigger an external api call and save the response to DB. Is it a good practice to do that from menu contributor?

  Hi,

  I think there is no problem, you can abstract some services if you need to. for example:

  • Create IDynamicMenuStore interface
  • Create DynamicMenuStore to implement IDynamicMenuStore interface

  public interface IDynamicMenuStore
  {
       Task<List<DynamicMenuItems>> GetMenuAsync();
  }
  
  public class DynamicMenuStore: IDynamicMenuStore, ITransientDependency
  {
       public Task<List<DynamicMenuItems>> GetMenuAsync()
       {
           ....
       }
  }
  
  public class MyMenuContributor : IMenuContributor
  {
      private readonly IDynamicMenuStore _dynamicMenuStore;
       
      public MyMenuContributor(IDynamicMenuStore dynamicMenuStore)
      {
          _dynamicMenuStore = dynamicMenuStore;
      }
  
      public async Task ConfigureMenuAsync(MenuConfigurationContext context)
      {
          if (context.Menu.Name == StandardMenus.Main)
          {
              await ConfigureMainMenuAsync(context);
          }
      }
  
      private Task ConfigureMainMenuAsync(MenuConfigurationContext context)
      {
          var dynamicMenus = await _dynamicMenuStore.GetMenuAsync();
              
          //...
      }
  }
