Components

Figure 1. Components overview (svg)

Racelogger

This module is responsible for extracting the data from the local running iRacing simulation software.

Racelogger is the data provider for the whole project.

Repository	racelogger
Language	Go
Tech	gRPC

iRacelog Web

This is the web frontend. It is used to show race data for both live and archived events.

Repository:

Repository	iracelog
Language	TypeScript
Tech	React, ant.design,

iRacelog Service Manager (Go)

This module is the main entry point to manage the backend services. It recieves messages from the racelogger and is responsible for the following tasks

• archive the recieved messages from the racelogger

• compute additional stats (such as stint durations, driver seat times, driver laps)

• database migration

Repository	iracelog-service-manager-go
Language	Go
Tech	gRPC, buf.build, ConnectRPC, OpenTelemetry, Postgresql, Migrate

iRacelog GraphQL

This component provides the search functionality for the iRacelog.

Repository	iracelog-graphql
Language	Go
Tech	GraphQL

Components (retired)

iRacelog WAMP Router

This module is the replacement for Crossbar.

It serves as the central point for distributing messages between the components according to the WAMP specification.

While crossbar provides a lot of features we actually don’t need much of them. The Nexus library in Go fullfills our needs and comes with a much smaller footprint.

Repository	iracelog-wamp-router
Language	Go
Tech	WAMP, Nexus

Racelogger (Python)

This module is responsible for extracting the data from the local running iRacing simulation software. The racelogger uses the python module pyirsdk to get access to the iRacing telemetry data. Racelogger is the data provider for the whole project.

Repository	racelogger
Language	Python
Tech	pyirsdk, WAMP, autobahn

iRacelog Service Manager (Python)

This module is the main entry point to manage the backend services. It recieves messages from the racelogger and is responsible for the distribution to other backend components, such as

• archive the recieved messages from the racelogger

• compute additional stats (such as stint durations, driver seat times, driver laps)

• gateway to linked subcomponents

Repository	iracelog-service-manager
Language	Python
Tech	crossbar, WAMP, autobahn

iRacelog Anaylsis Service

This module is responsible for processing incoming WAMP-messages from the racelogger. During live events it holds the current race state (including extra computations) and stores it periodically into the database.

Repository	iracelog-analysis-service
Language	TypeScript
Tech	WAMP, autobahn

Utilities

racelogctl (CLI)

Command line tool used for administrative tasks which are not yet available via web frontend.

This tool is also used for stress tests during development.

Repository	racelogctl
Language	Go
Tech	Cobra, Viper, WAMP, Nexus

Deployment

This repository contains samples for deploying the application in the following environments

• docker via docker compose

• kubernetes via Helm charts

Caution

The samples in this repository are designed for local test environments.

Repository	iracelog-deployment
Tech	Docker, Kubernetes, Helm

Sample installation

This setup is supposed for users who are familar with Linux servers. The ansible playbooks can be used to setup the application on IaaS (Infrastructure as a Service) machines.

The sample uses Hetzner (for IaaS) and Netcup (for domain services), but you may adjust the playbooks for other providers.

Repository	sample-setup
Language	Ansible, Python
Tech	Docker
