# Kentico Cloud View Model - Locally cached & Strongly Typed?

The Kentico Cloud Deliver API uses a CDN internally so that your content is available anywhere in the world in a few milliseconds. Even with that awesome speed, wouldn't it be great to locally cache your content?  
  
Also, what if you prefer working with strongly typed view models?  
  
This is where the [EmmTi.KenticoCloudConsumer.EnhancedDeliver](https://www.nuget.org/packages/EmmTi.KenticoCloudConsumer.EnhancedDeliver/) NuGet package (still in beta) comes to the rescue.

## NuGet Package

This project is available as a nuget package at [https://www.nuget.org/packages/EmmTi.KenticoCloudConsumer.EnhancedDeliver/](https://www.nuget.org/packages/EmmTi.KenticoCloudConsumer.EnhancedDeliver/)  
  
To install EmmTi.KenticoCloudConsumer.EnhancedDeliver, run the following command in the Package Manager Console  
  
```
PM > Install-Package EmmTi.KenticoCloudConsumer.EnhancedDeliver
```

## Quick Setup Guide

### Initial Setup

1. Follow the steps in the [Kentico Dancing Goat Example](https://github.com/Kentico/Deliver-Dancing-Goat-.NET-MVC/blob/master/README.md) to setup a sample site.  
2. Add the following config setting in appsettings of `web.config`. Tweak the cache time as you see fit.  
```
<add key="DeliveryContentCacheTimeSeconds" value="300"/>
```

### Creating the View Model

1. Create a new ViewModel and inherit from BaseContentItemViewModel  
2. Add a **ItemCodeName** constant with the code name for the Kentico Content Type  
3. Create public properties for other Content Elements  
4. Override MapContentForType method and map each field - See example  
  
```
using EmmTi.KenticoCloudConsumer.EnhancedDeliver.Helpers;
using KenticoCloud.Deliver;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace EmmTi.KenticoCloudConsumer.EnhancedDeliver.Sample.Models
{
    public class SampleViewModel : BaseContentItemViewModel
    {
        public const string ItemCodeName = "article";
        public HtmlString BodyCopy { get; set; }
        public string MetaDescription { get; set; }
        public string MetaKeywords { get; set; }
        public Dictionary<string, string> Personas { get; set; }
        public DateTime PostDate { get; set; }
        public List<SampleViewModel> RelatedArticles { get; set; }
        public string Summary { get; set; }
        public Asset TeaserImage { get; set; }
        public string Title { get; set; }

        protected override void MapContentForType(ContentItem content, int currentDepth)
        {
            BodyCopy = new HtmlString(content.GetString("body_copy"));
            MetaDescription = content.GetString("meta_description");
            MetaKeywords = content.GetString("meta_keywords");
            Personas = content.GetTaxonomyItems("personas");
            PostDate = content.GetDateTime("post_date");
            RelatedArticles = content.GetModularContent("related_articles").GetListOfModularContent<SampleViewModel>(currentDepth + 1);
            Summary = content.GetString("summary");
            TeaserImage = content.GetAssets("teaser_image").FirstOrDefault();
            Title = content.GetString("title");
        }
    }
}
``` 
  

### The Controller

In your Controller return the new ViewModel using the DeliveryFactory  
  
  
  

### The View

Use the strongly typed model in your View  
  
  

## See a full sample site

Clone an enhanced version of the Dancing Goat Sample site for a working example  
[https://github.com/emmanueltissera/Deliver-Dancing-Goat-Enhanced](https://github.com/emmanueltissera/Deliver-Dancing-Goat-Enhanced)  
  
It's just got the Homepage View converted to a strongly typed, locally cached version. I will be updating the rest of the views and code as and when I get some time.
