Data - Cosmos

👁 Nuget package

Cosmos Data project primarily contains Cosmos DB implementations based on the abstractions provided by , as well as some other utilities related to Cosmos DB.

Setup

Nuget package

First, install NuGet. Then, install Encamina.Enmarcha.Data.Cosmos from the package manager console:

PM> Install-Package Encamina.Enmarcha.Data.Cosmos

.NET CLI:

First, install .NET CLI. Then, install Encamina.Enmarcha.Data.Cosmos from the .NET CLI:

dotnet add package Encamina.Enmarcha.Data.Cosmos

How to use

In the following example, we will demonstrate how to configure and add an Cosmos DB implementation of the interface to the ServiceCollection, based on the .

public class Foo 
{
 [JsonProperty("id")]
 public string Id { get; set; }

 [JsonProperty("text")]
 public string Text { get; set; }
}

First, you need to add the to your project configuration. You can achieve this by using any configuration provider. The followng code is an example of how the settings would appear using the appsettings.json file:

 {
 // ...
 "CosmosOptions": {
 "AuthKey": "<Your-AuthKey>", // Authentication key required to connect with Azure Cosmos DB
 "Database": "<Your-Database>", // Database name to connect with Azure Cosmos DB
 "Endpoint": "<Your-Endpoint>", // Azure Cosmos DB service endpoint to use
 // ...
 },
 "CosmosDBContainerName": "<Your-Cosmos-DB-Container-Name>",
 // ...
 }

Next, in Program.cs or a similar entry point file in your project, add the following code:

// Entry point
var builder = WebApplication.CreateBuilder(new WebApplicationOptions
{
 // ...
});

// ...

// Or others configuration providers...
builder.Configuration.AddJsonFile(@"appsettings.json", optional: true, reloadOnChange: true); 

builder.Services.AddCosmos(builder.Configuration);
builder.Services.AddScoped<IAsyncRepository<Foo>>(sp => sp.GetRequiredService<ICosmosRepositoryFactory>()
 .Create<Foo>(builder.Configuration.GetValue<string>("CosmosDBContainerName")));

And now, you can resolve the IAsyncRepository<Foo> interface with construction injection:

public class MyClass
{
 private readonly IAsyncRepository<Foo> fooRepository;

 public MyClass(IAsyncRepository<Foo> fooRepository)
 {
 this.fooRepository = fooRepository;
 }

 public async Task TestAddFooAsync(CancellationToken cts)
 {
 await fooRepository.AddAsync(new Foo() { Text = "Foo1", Id = Guid.NewGuid().ToString()}, cts); 
 }
}

Within the NuGet package, you will find some extension methods related to Cosmos DB in .
