StratusCube.Extensions.Configuration.RavenDB

Use RavenDB as a configuration provider in dotnet.

The package will let you use RavenDB as a configuration provider. Either a collection or an entire database may be used as a provider. The provider can also make use of Collection or Database subscriptions to reload the configuration changes.

Getting Started

Add the package to your project from nuget.

dotnet add package StratusCube.Extensions.Configuration.RavenDB

The RavenDBConfigurationExtensions class resides in the namespace Microsoft.Extensions.Configuration. In most new web projects the namespace will not need to be specified in the Program.cs file.

Usage

The following is an example implementation. In the Program.cs you can add the following:

Program.cs Boilerplate

//. Document store to use for the config
using Microsoft.Extensions.Configuration;

IDocumentStore configStore = new DocumentStore {
    Database = "MyDatabase" ,
    Urls = new[] { "http://localhost:8080" } ,
};

var builder = WebApplication.CreateBuilder(args);

Add Single Raven Document

builder.Configuration.AddRavenDocument(
    documentStore: configStore ,
    //. the document ID to use for the configurations
    documentId: "MyDocumentID" ,
    //. if true a subscriber will be used to notify when the collection has changed
    //. and if so load the new configuration values
    reloadOnChange: true ,
    //. optionally add a logger, in this case the logger will grab the
    //. configuration section of logging and add a console provider
    config => config
        .AddConfiguration(builder.Configuration.GetSection("Logging"))
        .AddConsole()
);

Add Raven Collection Source

builder.Configuration.AddRavenDbCollection(
    documentStore: configStore ,
    //. the collection to use for the configurations
    collectionName: "MyCollection" ,
    //. if true a subscriber will be used to notify when the collection has changed
    //. and if so load the new configuration values
    reloadOnChange: true ,
    //. if true then the collection will be prefixed to the configuration keys
    //. true: [MyCollection:Foo:Field]
    //. false: [Foo:Field]
    useCollectionPrefix: true ,
    //. optionally add a logger, in this case the logger will grab the
    //. configuration section of logging and add a console provider
    loggerConfig: config => config
        .AddConfiguration(builder.Configuration.GetSection("Logging"))
        .AddConsole()
);

Add Raven Database

builder.Configuration.AddRavenDb(
    //. The database specified in the IDocumentStore will be used
    //. for the configurations
    documentStore: configStore ,
    //. if true a subscriber will be used to notify when the collection has changed
    //. and if so load the new configuration values
    reloadOnChange: true ,
    //. optionally add a logger, in this case the logger will grab the
    //. configuration section of logging and add a console provider
    config => config
        .AddConfiguration(builder.Configuration.GetSection("Logging"))
        .AddConsole()
);
