NATS-WebUI is a web app for monitoring messages on NATS publications as well as NATS Server diagnostics. This project was built to explore building web-backends in Rust and uses the following stack:
Add a server by entering its hostname, port, and monitoring port. The monitoring endpoint is called server-side, so the NATS server host must be resolvable and reachable from the server hosting the WebUI.
In order to subscribe and receive messages from publications, the subjects must be added to the subject hierarchy on the server dashboard. The hierarchy is represented as a subject tree where each node in the tree contains a single subject token. The editor takes input as a tab-spaced tree. For example, to represent the following subjects:
Create a client to monitor publications. Once the subjects have been entered as previously stated, they should show up on the right side of the client screen. Select the subjects to subscribe to and click the "link" icon to start receiving messages.
