Lussatite.FeatureManagement.SessionManagers 1.6.2

Lussatite.FeatureManagement.SessionManagers

Various read-only ISessionManager implementations which are compatible with .NET Standard 2.0. These implementations do not write back to the underlying value store.

ISessionManager Implementations

While these ISessionManager implementations are written for Lussatite.FeatureManagement, they are compatible with the Microsoft ISessionManager interface and could be used with the Microsoft FeatureManager implementation.

ClaimsPrincipalSessionManager

A read-only ISessionManager implementation that examines ClaimsPrincipal claims of type "feature_flag" to obtain the feature value. The value of the claim is either the feature name to indicate true, or the feature name prefixed with an exclamation point ("!") to indicate false.

SqlSessionManager

An ISessionManager implementation that uses user-provided DbCommand objects to obtain/update its values. Write-back is optional for the SetValue() call.

In order to construct the SqlSessionManager, you need to provide it with a SqlSessionManagerSettings object. See the SessionManagers.SqlClient or SessionManagers.SQLite for default setting objects which already have the necessary SQL statements.

var settings = new SQLServerSessionManagerSettings
{
    ConnectionString = "some connection string",
    EnableSetValueCommand = true,
};
var sqlSessionManager = new SqlSessionManager(settings);
// inject the sqlSessionManager into the LussatiteLazyCacheFeatureManager constructor

CachedSqlSessionManager

A cached ISessionManager implementation that uses a user-provided DbCommand to obtain its values. The results for a particular feature flag name will be cached for 60 seconds. This object is configured using a CachedSqlSessionManagerSettings object.

It uses LazyCache under the hood.

StaticAnswerSessionManager

An ISessionManager implementation which always returns the same answer for the feature name. It's really only useful in testing scenarios where you need to validate both control pathways in the code.
