Functionality

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

  • DataEngine: The engine that handles the write and deletion of relation tuples and attributes.
    • Read here about how the relational data is stored.
  • CheckEngine: 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.
  • LookupSubjectEngine: The engine that can answer: Which subjects of type T have permission Y on entity:X? For that, use the Lookup function.
  • LookupEntityEngine: The engine that can answer: Which resources of type T can entity:X have permission Y? For that, use the LookupEntity function.

Usage

Install the package from NuGet:

If using Postgres:

dotnet add package Valtuutus.Data.Postgres

If using SqlServer:

dotnet add package Valtuutus.Data.SqlServer

Adding to DI:

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

See examples of how to define your schema here.

If using Postgres:

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

If using SqlServer:

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

Using check 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.AddValtuutusData()
    .AddPostgres(_ => () => new NpgsqlConnection(builder.Configuration.GetConnectionString("PostgresDb")!))
    .AddConcurrentQueryLimit(10);

Change your data provider according to your database.

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")
            ...
