This NATS client is a cross-platform desktop & web application written in Flutter. The client allows users to easily watch & manage NATS messages.
This application currently supports Windows, Linux, macOS and Web platforms.
- Connect to a single NATS server using either plain (
nats://) or WebSocket (ws://) schemes - TLS connection support with optional custom certificates
- Subscribe to multiple subjects
- Automatic re-connect upon lost connection
- Filter received messages
- Find text in received messages
- Send custom messages
- See message details, such as headers, subject and payload. JSON payloads are automatically formatted and syntax highlighted as well!
- Light and Dark themes
- Most recent connection information & theme are persisted between app runs
See the help documentation for more details on how to use the application.
This application is also available via Docker Hub. Please note that running the application in Docker means you're running the web flavor. Only the ws:// scheme is available in the browser as explained in the help documentation. Be sure to enable WebSocket support on your target NATS server if you intend to use the Docker version.
To install and run via Docker:
docker run -d -p 8080:80 --name nats-client nverbeek/nats-client-flutter
You may then access the application in your favorite browser at http://localhost:8080.
To build NATS Client UI, you must first install Flutter for your platform, and get an editor. I highly recommend Android Studio for building, but VS Code is a great second option.
Both Android Studio and VS Code, when setup properly, will automatically offer devices to run this application on and debug.
To build a release, use the following command for your target platform:
flutter build windows
flutter build macos
flutter build linux
flutter build web
To build a docker version of the client, run the following command (from the root of the source code):
docker build -t nats-client-flutter .
I am always looking for suggestions on how to improve the NATS Client UI. If you find any bugs or have an idea for a new feature, please let me know by opening a report in the issue tracker on GitHub.
