Installation

docker run -d -p 80:80 sphqxe/nats-webui:latest

Usage

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:
```
time.us
time.us.east
time.us.east.atlanta
time.eu.east
time.eu.warsaw
```
Input the subject tree as such:
```
time
  us
    east
      atlanta
  eu
    east
    warsaw
```
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.
