Mix features into ASP.NET Core Projects from Gists

To complete the picture of making it easy as possible to compose ASP.NET Core Apps & easily install features we've added mix support to the dotnet tools:

dotnet tool install --global x

The same functionality is also built into the Windows app dotnet tool, both can be updated to the latest version with:

.NET 6.0 (Windows/macOS/Linux):

dotnet tool update -g x

.NET 6.0 (Windows x64):

dotnet tool update -g app

mix-enabled dotnet tools

mix works exactly the same in all dotnet tools, which just needs the tool name prefixed before the mix command:

x mix ...
app mix ...

mix Usage

x mix is designed around applying ASP.NET Core features captured in GitHub gists to your local .NET Core projects.

Type x mix ? for a quick Usage Summary:

View all published gists:
   x mix

Simple Usage:
   x mix <name> <name> ...

Mix using numbered list index instead:
   x mix 1 3 5 ...

Delete previously mixed gists:
   x mix -delete <name> <name> ...

Use custom project name instead of current folder name (replaces MyApp):
   x mix -name ProjectName <name> <name> ...

Replace additional tokens before mixing:
   x mix -replace term=with <name> <name> ...

Multi replace with escaped string example:
   x mix -replace term=with -replace "This Phrase"="With This" <name> <name> ...

Only display available gists with a specific tag:
  x mix [tag]
  x mix [tag1,tag2]

Although most of the time you're only going to run 2 commands, viewing available features with:

x mix

Where it displays different features that can be added to your App, where they're added to and the author of the Gist:

Mix in Features into ASP.NET Core Apps

It should be noted that ModularStartup and mix dotnet tool aren't limited to ServiceStack Apps, they're a generic solution that can easily add features to any .NET Core App. E.g. some of ServiceStack features relies on external dependencies which utilizes the same dependency registration used in all ASP.NET Core Apps, e.g running:

x mix mongodb

Applies the mongodb feature to your HOST project as instructed by the to: $HOST modifier above that it finds by using the first folder containing either appsettings.json, Program.cs or Startup.cs and writing the following mongodb Gist file:

namespace MyApp
    public class ConfigureMongoDb : IConfigureServices
        IConfiguration Configuration { get; }
        public ConfigureMongoDb(IConfiguration configuration) => Configuration = configuration;

        public void Configure(IServiceCollection services)
            var mongoClient = new MongoClient();
            IMongoDatabase mongoDatabase = mongoClient.GetDatabase("MyApp");

With all MyApp tokens replaced with the Project Name using the same replacement rules as new projects, i.e:

  • MyApp will be replaced with ProjectName
  • my-app will be replaced with project-name
  • My App will be replaced with Project Name

By default it assumes the folder name is the project name, that's overridable using the -name flag:

x mix -name ProjectName mongodb

This feature also installs the MongoDB.Driver NuGet package as instructed by the _init command in the mongodb feature.

So after just a single mix command and App restart, it's now configured and running with MongoDB!

Registering MongoDB Auth Repository

As a design goal mix features are designed to be layerable where you can existing features that builds upon existing registrations, for example you can later configure your App to enable auth and configure it to use a MongoDbAuthRepository with:

x mix auth auth-mongodb

Mix in DB Support

All DB servers are just as easily configurable, which we can quickly find using a [db] tag search:

x mix [db]


search term needs to be quoted in unix shells, e.g: '[db]'

Which will list all available [db] providers:

Results matching tag [db]:

   1. redis      Use ServiceStack.Redis            to: $HOST  by @ServiceStack  [db]
   2. sqlserver  Use OrmLite with SQL Server       to: $HOST  by @ServiceStack  [db]
   3. sqlite     Use OrmLite with SQLite           to: $HOST  by @ServiceStack  [db]
   4. postgres   Use OrmLite with PostgreSQL       to: $HOST  by @ServiceStack  [db]
   5. mysql      Use OrmLite with MySql            to: $HOST  by @ServiceStack  [db]
   6. oracle     Use OrmLite with Oracle           to: $HOST  by @ServiceStack  [db]
   7. firebird   Use OrmLite with Firebird         to: $HOST  by @ServiceStack  [db]
   8. dynamodb   Use AWS DynamoDB and PocoDynamo   to: $HOST  by @ServiceStack  [db]
   9. mongodb    Use MongoDB                       to: $HOST  by @ServiceStack  [db]
  10. ravendb    Use RavenDB                       to: $HOST  by @ServiceStack  [db]
  11. marten     Use Marten NoSQL with PostgreSQL  to: $HOST  by @ServiceStack  [db]

   Usage:  x mix <name> <name> ...

  Search:  x mix [tag] Available tags: auth, config, db, feature, lib, mq, project, react, sharp, svg, ui, vue

Advanced:  x mix ?

So we can install Redis with:

x mix redis

Where it will apply the Redis Gist below:

namespace MyApp
    public class ConfigureRedis : IConfigureServices, IConfigureAppHost
        IConfiguration Configuration { get; }
        public ConfigureRedis(IConfiguration configuration) => Configuration = configuration;

        public void Configure(IServiceCollection services)
                new RedisManagerPool(Configuration.GetConnectionString("Redis") ?? "localhost:6379"));

        public void Configure(IAppHost appHost)
            appHost.GetPlugin<SharpPagesFeature>()?.ScriptMethods.Add(new RedisScripts());

The configuration is declarative where it only runs Configure(IAppHost appHost) in ServiceStack Apps and only adds the RedisScripts if it's configured with #Script Pages, otherwise any additional configuration is inert and isn't run.

Typically DB's will require you to specify your App DB's connection string to your external DB (with a default fallback) - where typically the most effort required to enable a feature is adding a Connection String in your appsettings.json.

Composable Features

A nice characteristic about "no-touch" layerable features are that they're composable, where mix will let you hand-pick all features you want in a single command. For example you can enable Authentication, register an RDBMS Auth Repository using SQL Server with:

x mix auth auth-db sqlserver

Which will apply the Configure.Auth.cs, Configure.AuthRepository.cs and Configure.Db.cs gists.

If you later wanted to switch to PostgreSQL, you can mix it in with:

x mix postgres

Where it will override Configure.Db.cs to use the postgres version, leaving any custom logic in Configure.Auth.cs or Configure.AuthRepository.cs untouched.

Or if you later want to change the Auth Repository to use Redis instead, you can run:

x mix auth-redis

Where it will override the existing Configure.AuthRepository.cs added by auth-db.

Undo mix

In addition to being easy to add, mix makes it easy to undo where you can specify the -delete flag to remove all the Gist files added by all features, e.g:

x mix -delete auth auth-db sqlserver

Which will let you review all the files in each Gist that will deleted, then hit Enter to confirm:

Delete 1 file from 'auth' https://gist.github.com/gistlyn/1ec54e10d44f87e0f20daaf7e2248fea:


Delete 1 file from 'auth-db' https://gist.github.com/gistlyn/16fddde0763b3eee516d670ab9fab194:


Delete 1 file from 'sqlserver' https://gist.github.com/gistlyn/7075e53e1fe69d3da12996677b5f3a5a:


Proceed? (n/Y):

Encapsulated Features

A nice benefit of decoupling features into modular classes is that you're able to a richer and more customizable out-of-the-box experience.

Instead of overloading users with daunting amounts of configuration required in common medium-sized Apps, most templates will start with an empty slate and leave it for users to read about each feature then decide how to hand-pick different configuration to slot it into their own App's configuration.

On the flip-side if you provide too much configuration Developers wont be confident to know what configuration belongs to which feature and which feature are interconnected or can be safely removed without breaking their App.

With modular features we can encapsulate configuration in a single .cs file that's primed with the popular well-known configuration for the feature. E.g. The Auth Repositories include an example of maintaining a custom UserAuth model, registering the Auth Event to populate their additional fields on Authentication and sample code necessary for ensuring a specific Admin User is created on Startup:

namespace MyApp
    // Custom User Table with extended Metadata properties
    public class AppUser : UserAuth
        public string ProfileUrl { get; set; }
        public string LastLoginIp { get; set; }
        public DateTime? LastLoginDate { get; set; }

    public class AppUserAuthEvents : AuthEvents
        public override void OnAuthenticated(IRequest req, IAuthSession session, IServiceBase authService, 
            IAuthTokens tokens, Dictionary<string, string> authInfo)
            var authRepo = HostContext.AppHost.GetAuthRepository(req);
            using (authRepo as IDisposable)
                var userAuth = (AppUser)authRepo.GetUserAuth(session.UserAuthId);
                userAuth.ProfileUrl = session.GetProfileUrl();
                userAuth.LastLoginIp = req.UserHostAddress;
                userAuth.LastLoginDate = DateTime.UtcNow;

    public class ConfigureAuthRepository : IConfigureAppHost, IConfigureServices, IPreInitPlugin
        public void Configure(IServiceCollection services)
            services.AddSingleton<IAuthRepository>(c =>
                new OrmLiteAuthRepository<AppUser, UserAuthDetails>(c.Resolve<IDbConnectionFactory>()) {
                    UseDistinctRoleTables = true

        public void Configure(IAppHost appHost)
            var authRepo = appHost.Resolve<IAuthRepository>();

            CreateUser(authRepo, "admin@email.com", "Admin User", "p@55wOrd", roles:new[]{ RoleNames.Admin });

        public void BeforePluginsLoaded(IAppHost appHost)
            appHost.AssertPlugin<AuthFeature>().AuthEvents.Add(new AppUserAuthEvents());

        // Add initial Users to the configured Auth Repository
        public void CreateUser(IAuthRepository authRepo, 
            string email, string name, string password, string[] roles)
            if (authRepo.GetUserAuthByUserName(email) == null)
                var newAdmin = new AppUser { Email = email, DisplayName = name };
                var user = authRepo.CreateUserAuth(newAdmin, password);
                authRepo.AssignRoles(user, roles);

All captured within a working configuration. You can start appreciating the instant utility of mix once you imagine what it was like before with how much time an effort it would've taken to scan through docs, learn about each feature independently to be able to piece together equivalent functionality.

Mix in Auth Repository

As it can take a while to piece together how to configure your preferred Auth Repository, use a Custom User Model and utilize Auth Events to populate it, we now recommend using mix to configure your preferred Auth Repository, which you can query with:

x mix [auth]

To display the current list of available Auth Repositories:

Results matching tag [auth]:

   1. auth              Configure AuthFeature                        to: $HOST  by @ServiceStack [auth]
   2. auth-db           Use OrmLite Auth Repository (requires auth)  to: $HOST  by @ServiceStack [auth]
   3. auth-redis        Use Redis Auth Repository (requires auth)    to: $HOST  by @ServiceStack [auth]
   4. auth-memory       Use Memory Auth Repository (requires auth)   to: $HOST  by @ServiceStack [auth]
   5. auth-dynamodb     Use DynamoDB Auth Repository (requires auth) to: $HOST  by @ServiceStack [auth]
   6. auth-mongodb      Use MongoDB Auth Repository (requires auth)  to: $HOST  by @ServiceStack [auth]
   7. auth-ravendb      Use RavenDB Auth Repository (requires auth)  to: $HOST  by @ServiceStack [auth]
   8. auth-marten       Use Marten Auth Repository (requires auth)   to: $HOST  by @ServiceStack [auth]
   9. feature-authrepo  List and Search Users in an Auth Repo        to: $HOST  by @ServiceStack [feature,auth]

Mix in MQ Server

Likewise we now recommend using mix to configure your preferred MQ Service, other than being quicker to add, it proposes adopting a naming convention in app settings and file names that other mix features can also make use of:

x mix [mq]

Currently available list of MQ Services:

Results matching tag [mq]:

   1. backgroundmq  Use Memory Background MQ                    to: $HOST  by @ServiceStack  [mq]
   2. rabbitmq      Use RabbitMQ                                to: $HOST  by @ServiceStack  [mq]
   3. sqs           Use AWS SQS MQ                              to: $HOST  by @ServiceStack  [mq]
   4. servicebus    Use Azure Service Bus MQ                    to: $HOST  by @ServiceStack  [mq]
   5. redismq       Use Redis MQ                                to: $HOST  by @ServiceStack  [mq]
   6. feature-mq    Simple MQ Feature to test sending Messages  to: $HOST  by @ServiceStack  [feature,mq,sharp]

Mix in NUglify

You can configure your ServiceStack App to use Nuglify's Advanced HTML, CSS, JS Minifiers using mix with:

x mix nuglify

Which will write Configure.Nuglify.cs to your HOST project.

Mix in Prebuilt Recipes and Working Examples

ModularStartup and mix can scale up to complete working examples which can provide instant utility and integration of a feature into your existing App. By contrast most working examples are typically made available off to the side in stale projects which need to be downloaded and run in isolation. If it still works you'd then have to compare the project files with your project and carefully copy over the differences you'd think your App needs to replicate its functionality. This can be very time consuming to the point where a lot of users will skip trying to download & run the example and instead try to manually configure it in their App.

All mix features add their files to your App's Physical Project Structure where configuration is added to your Host Project, Service Contracts are added to your ServiceModel/ folder and Service Implementations added to your ServiceInterface/ folder and any Web assets added to your App's wwwroot/.

They can also be added to both multi and single project solutions in which case they'll be added to ServiceInterface and ServiceModel folders in your App's project folder using the same namespace as used in multi-project solutions, making it easy to upgrade to a multi-project solution later.


The example-validation mix is a complete working validation example that's typical of a real-world validation example complete with Authentication integration allowing each authenticated user to manage their own private Contacts list.

Now after restarting your App you'll be able to add contacts by clicking on the new Contacts link in your App's main menu:

cd Acme

dotnet run

After you're done reviewing the example you can either refactor it to handle your App's requirements or completely remove it from your App with:

x mix -delete example-validation


The feature-mq adds MQ support to your App, complete with UI and includes 2 different ways of calling MQ Services in ServiceStack, just like example-validation above, feature-mq is another complete working example with both UI and Service implementation in the following files:

As Configure.Mq.cs? is optional it will only add it if doesn't already exist, so it will either use your existing MQ configuration or configure your App to use the In Memory BackgroundMqService implementation.

Add feature-mq to your project with:

x mix feature-mq

This will add the TestMq Service and make it available to your MQ endpoint. TestMq is a regular service that updates values in the App's registered ICacheClient and returns the Cache's current values as well as the internal Stats of the MQ:

public class MqServices : Service
    public IMessageService MqService { get; set; }

    public void Any(PublishMq request)

    public object Any(TestMq request)
        if (!string.IsNullOrEmpty(request.Name))
            Cache.Set("mq.name", request.Name);
        if (request.Add > 0)
            Cache.Increment("mq.counter", (uint)request.Add);
        else if (request.Add < 0)
            Cache.Decrement("mq.counter", (uint)(request.Add * -1));

        return new TestMqResponse {
            Name = Cache.Get<string>("mq.name"),
            Counter = Cache.Get<long>("mq.counter"),
            StatsDescription = MqService.GetStatsDescription(),

The 2 ways to call a MQ Service is directly using the publish or sendOneWay APIs (available in all ServiceStack Service Clients) where it send the request to the Service's /oneway endpoint which will automatically publish it to the registered MQ.

Alternatively you can publish the Request DTO yourself from a different Service Implementation as done in PublishMq, as-is typical for Services that queues sending emails without blocking Service Execution.

The feature's UI allows you to publish TestMq messages using either approach:

client = new JsonServiceClient('/');

var oneway = document.querySelector('input[name=mq-publish]:checked').value === "OneWay";
if (oneway) {
    client.publish(new TestMq({ name: $txtName.value, add: parseInt(add) }))
} else {
    client.post(new PublishMq({ name: $txtName.value, add: parseInt(add) }))

Both approaches end with the same result with the TestMq Request DTO published and executed by the registered MQ Service as shown in the UI which is periodically updated with the current state in the Cache and the internal stats of the MQ Service showing how many messages it processed.


Another UI feature mix available is a UI to browse and search for registered users in an Auth Repository.

This wasn't generically possible before as IAuthRepository didn't previously provide any API's to be able to query all Users, which is now available in the new IQueryUserAuth API:

public interface IQueryUserAuth
    List<IUserAuth> GetUserAuths(string orderBy = null, int? skip = null, int? take = null);
    List<IUserAuth> SearchUserAuths(string query, string orderBy = null, int? skip = null, int? take = null);

This is now implemented in all ServiceStack Auth Repositories although there are limitations depending on the queryability of the underlying data provider.

Searching in these Auth Repositories are efficient and searches in UserName, Email, DisplayName and Company fields:

  • OrmLiteAuthRepository
  • InMemoryAuthRepository
  • MongoDbAuthRepository

For RavenDB it reuses the existing Username/Email indexes so only searches UserName, Email fields and only performs a StartsWith/EndsWith search as allowed by RavenDB:

  • RavenDbUserAuthRepository

Searches and Order By's are very inefficient in Redis as it needs to deserialize all users to perform the querying/sorting on the client. Just paging through users with skip/take is efficient as it only needs to deserialize the partial resultset.

  • RedisAuthRepository

All queries performs a table scan in DynamoDB but searches all fields:

  • DynamoDbAuthRepository

API Usage

These API's are accessible from an IAuthRepository dependency, if you're using a custom Auth Repository it will need to implement IQueryUserAuth otherwise calling these APIs (and feature) will throw a NotSupportedException:

AuthRepository.GetUserAuths(orderBy:fieldName, skip:skip, take:take)
AuthRepository.SearchUserAuths(query:q, orderBy:fieldName, skip:skip, take:take)

The orderBy is the field name you want to order the results by, e.g. UserName and can suffixed with the DESC modifier to order results in descending order, e.g. UserName DESC.

In #Script these API's are available in camelCase off authRepo using a JS Object literal as seen in users.html page usage of this feature:

{‎{ authRepo.searchUserAuths({ query:qs.q, take: pageSize, skip: pageSize*page }) | to => users }‎}

Users UI

Clicking the Users menu item will show you a list of searchable and pageable registered Users in a summary view:

Clicking on a user will show you a complete list of fields stored for that user, including any custom fields, if you're using a Custom UserAuth table:
