Sample applications and a dotnet new project template for getting started with Trax.

Project Template

Scaffold a new Trax server with the control room, timetable, and PostgreSQL persistence already wired up:

dotnet new install Trax.Samples.Templates
dotnet new trax-server -n MyApp

With a custom connection string:

dotnet new trax-server -n MyApp --ConnectionString "Host=db.example.com;Port=5432;Database=myapp;Username=myuser;Password=secret"

The template creates an ASP.NET Core project with:

• AddTrax configured with AddEffects (Postgres, junction logging, junction progress), AddMediator, and AddScheduler
• AddTraxDashboard for the control room
• AddScheduler with a sample HelloWorldTrain departing every 20 seconds
• A Trains/ directory with an example train, cargo type, interface, and stop

Sample Applications

Scheduler Sample

A full working example of the Trax scheduler with ETL-style pipelines, fleet scheduling, connected departures, dormant trains, and journey log cleanup.

Running it:

# Start PostgreSQL
cd Trax.Samples
docker compose up -d

# Run the sample
dotnet run --project samples/Trax.Samples.Scheduler

Then open http://localhost:5298/trax to see the control room.

The sample includes:

• HelloWorldTrain — a simple scheduled train that logs a greeting every 20 seconds
• ExtractImportTrain — a multi-stop ETL train with 10 parallel manifests departing every 5 minutes
• TransformLoadTrain — a connected departure that runs after extract arrives
• DataQualityCheckTrain — a dormant train waiting in the yard, activated from a junction when anomalies are detected
• Journey log cleanup configuration for the HelloWorld train

Flowthru Spaceflights

A data pipeline sample using the Flowthru project conventions, demonstrating Trax trains in an ML-style pipeline context.
