Tessellate 1.0.45-preview

Tessellate.Service

The main entry point for the Tessellate microservice framework.

Installation

dotnet add package Tessellate
dotnet add package Tessellate.Messaging.RabbitMq

Quick start

1. Define your service

public class MyService : ITessellate
{
    public void RegisterServices(IServiceCollection services)
    {
        // Register your custom services here
    }
}

2. Bootstrap in Program.cs

await TessellateService<MyService>
    .Initialise()
    .WithModule<RabbitMqModule>() // Optional, but it's not a microservice without an AMQP transport!
    .Run();

That's it. Any IConsumer<T> in the assembly is discovered and wired up automatically.

Sending messages

Inject IPublisher wherever you need to send:

public class MyConsumer(IPublisher publisher) : IConsumer<TriggerReport>
{
    public async Task Consume(TriggerReport message)
    {
        await publisher.Publish(new ReportGenerated(message.ReportId));
    }
}

Consuming messages

public class ReportGeneratedConsumer : IConsumer<ReportGenerated>
{
    public async Task Consume(ReportGenerated message)
    {
        // handle the message
    }
}

No registration required — the framework discovers it automatically.

Background services

public class HealthCheckService : IRecurringBackgroundService
{
    public int IntervalMs => 30_000;

    public async Task ExecuteAsync()
    {
        // runs every 30 seconds
    }
}

Register it on the builder:

await TessellateService<MyService>
    .Initialise()
    .WithModule<RabbitMqModule>()
    .AddBackgroundService<HealthCheckService>()
    .Run();

Startup hooks

public class MyStartupHook(MyDbContext db) : IStartupHook
{
    public async Task OnStartup()
    {
        await db.Database.MigrateAsync();
    }
}

Register in your service module:

services.AddScoped<IStartupHook, MyStartupHook>();

Configuration

Configuration is read from the standard .NET configuration stack (appsettings.json, environment variables, etc). Access it via ISettings:

public class MyConsumer(ISettings settings) : IConsumer<MyMessage>
{
    public Task Consume(MyMessage message)
    {
        var value = settings["MySection:MyKey"];
    }
}
