Customizing nopCommerce

We are developing an nopCommerce based application. Our login page needs to be minimalistic and would need only an email id, password entry fields and a Login button.

Could you point me to best practices for achieving the above objective ?

Do I modify the corresponding pages found in \Presentation\Nop.Web\Views\Customer\ & controllers in \Presentation\Nop.Web\Controllers\

Or

Is there a better way of doing this and organizing all the modified files in one place/folder so that upgrading to future versions of nopCommerce will not be difficult ?

The requirement is to ensure that all the changes made to the project(views/controllers etc) are in one folder so that they are not overwritten when we upgrade to a newer version of nopCommerce.

I read somewhere that you can copy stuff you need to change (Login.chtml, CustomerController) to Themes/DefaultClean and then make your changes in this folder. I dont remember where i read it.

I feel doing so will make it that much easier to maintain our codebase because all your custom code is in one place/folder/sub folders

Is this a best practise? And is there a disadvantage to this method of doing things?

The best way to modify your nopCommerce project without changing anything in the core code would be to use the plugin functionality which is described here (assuming you're using the newest version 4.40).

To change the login page you would then need to create your modified version as a .cshtml file in your plugin. You then need to set this file as Content and set the Copy to Output Directory property to Copy if Newer or Copy Always.

You also need to implement the IViewLocationExpander interface so that the Razor Engine knows that it should use your custom Login Page. The implementation should look something like this:

public class MyViewLocationExpander : IViewLocationExpander
{
   public IEnumerable<string> ExpandViewLocations(ViewLocationExpanderContext context, IEnumerable<string> viewLocations)
   {
      if(context.ViewName == "Login")
      {
         viewLocations = new[] { "PathToCustomLoginPage" }.Concat(viewLocations);
      }

      return viewLocations;
   }

   public void PopulateValues(ViewLocationExpanderContext context)
   {
      return;
   }
}

After that you also need to register your ViewExpander by implementing the INopStartup interface. The implementation would look something like this:

public class MyStartup : INopStartup
{
   public int Order => int.MaxValue;

   public void Configure(IApplicationBuilder application)
   {
   }

   public void ConfigureServices(IServiceCollection services, IConfiguration configuration)
   {
      services.Configure<RazorViewEngineOptions>(options =>
      {
         options.ViewLocationExpanders.Add(new MyViewLocationExpander());
      });
   }
}
