MQTT Web Frontend: Publish, Subscribe and see Topic Status in a comfortable UI.

Download mqtt-admin.zip, unzip, put it on a webserver and open index.html with a modern browser. You can also give it a try by just visiting https://hobbyquaker.github.io/mqtt-admin

mqtt-admin offers 3 tabs, Publish, Subscribe and Status, these are described in more detail below. Topic input fields offer autocompletion, mqtt-admin subscribes # to get all availabe topics to be able to offer this. Broker settings, the UI state, subscriptions and the publish history are persisted in your browser local storage.

Just enter a topic and a payload and click the publish button. The payload input field can be resized vertically and has a built in JSON linter - a checkmark below the input field will indicate valid JSON.

Every publish is saved in the history table, you can refill the input fields by clicking in history, a double click immediatly publishes again (not retained).

It's possible to open a unlimited number of subscriptions tabs that can contain a unlimited number of single subscriptions. You can color your subscriptions, but you have to select a color before you enter a topic and press enter. Subscription tabs can be renamed by double-clicking on the name. Every subscription tab has Play/Pause/Stop buttons, pause will cache incoming messages and delay insertion into the DOM until you activate play again. The trash button just clears the table.

The status table shows the last-received payload of the listed topics, it's meant to keep an eye on e.g. current sensor data without being interested in previous data.

• This tool is meant to be used with keyboard and mouse, I do not plan any efforts on optimizing it for touch devices.
• Connecting to test.mosquitto.org will stress your browser (Many retained topics, big payloads, ...).

mqtt-admin contains some syntactic sugar for mqtt-smarthome users (special columns in status tab, auto-completion of // to /status/ and /set/)

Pull Requests welcome!
