Functionality

The library is designed to be simple and easy to use. Each subset of functionality is divided in engines. The engines are:

  • ICheckEngine: The engine that handles the answering of two questions:
    • Can entity U perform action Y in resource Z? For that, use the Check function.
    • What permissions entity U have in resource Z? For that, use the SubjectPermission function.
  • ILookupSubjectEngine: The engine that can answer: Which subjects of type T have permission Y on entity:X? For that, use the Lookup function.
  • ILookupEntityEngine: The engine that can answer: Which resources of type T can entity:X have permission Y? For that, use the LookupEntity function.
  • IDataWriterProvider: This is the provider that can write your relational or attribute data.
  • Read here about how the relational data is stored.

Usage

Install the package from NuGet:

If using Postgres:

dotnet add package Valtuutus.Data.Postgres

If using SqlServer:

dotnet add package Valtuutus.Data.SqlServer

If you prefer using an InMemory provider:

dotnet add package Valtuutus.Data.InMemory

Adding to DI:

builder.Services.AddValtuutusCore(c =>
        ...

See examples of how to define your schema here.

If using Postgres:

builder.Services
    .AddPostgres(_ => () => new NpgsqlConnection(builder.Configuration.GetConnectionString("PostgresDb")!));

If using SqlServer:

builder.Services
    .AddSqlServer(_ => () => new SqlConnection(builder.Configuration.GetConnectionString("SqlServerDb")!));

If using InMemory:

builder.Services
    .AddInMemory();

Database migrations

If you are using a DB provider to store your data, please look at the scripts that create the tables that Valtuutus require to function.

Schema and table name customization

Our database providers allows the customization of schema and table names to your needs. When adding to dependency injection, checkout the optional parameter.

Using query concurrent limiting

It is expected that you don't want to allow Valtuutus to expand queries while it has resources. The default limit is 5 concurrent queries for the same request. To change that, you can use the AddConcurrentQueryLimit method, for example:

builder.Services
    .AddPostgres(_ => () => new NpgsqlConnection(builder.Configuration.GetConnectionString("PostgresDb")!)) // Replace this with any provider you want
    .AddConcurrentQueryLimit(10);

Change your data provider according to your database.

Caching

Valtuutus supports caching the calls to the engines through the Valtuutus.Data.Caching package. To use it, install like:

dotnet add package Valtuutus.Data.Caching

In your DI setup, add the caching component:

builder.Services
    .AddPostgres(_ => () => new NpgsqlConnection(builder.Configuration.GetConnectionString("PostgresDb")!)) // Replace this with any provider you want
    .AddCaching(); // <-- This line

This packages requires that you set up the amazing FusionCache library. Click here for more information.

Telemetry

The library uses OpenTelemetry to provide telemetry data. To enable it, just add a source with the name "Valtuutus":

builder.Services
    .AddOpenTelemetry()
    .WithTracing(telemetry =>
    {
        telemetry
            .AddSource("Valtuutus")
            ...
