``` As you can see code is minimal - it will fit a Frame, webui css / theme will be added by webUI after loaded, so you do not need to add any, you can use any of existing class available in webUI. Communication between frame and main window is done by messages using objects (string / array based), do not use any object that could ne be cloned or loading will fail. --- ### Send message message structure used by `window.parent.postMessage(msg, '*');` has a defined format, some parameters are madatories, some are optionals and some depend on message type: `{type:'', target:'webui', id:'[origin]', noDispatch:[true], XXX:YYY}` `` is mandatory, it define the purpose of the message `target:'webui'` is mandatory, it help to screen the message `id:'[origin]'` is optionnal, it define which id must read the response if any, if present it can be used by extension to filter message, no id means the message is for everyone `noDispatch:[true]` is optionnal, if true it will prevent to send answer if any, if not or set to false, it will send answer message if any `XXX:YYY` are optionals/mandatories according message type --- ### Send GCODE command or ESP command Example: `{type:'cmd', target:'webui',id:'terminal', content:'[ESP111]'}` **type** is `cmd` (mandatory) **target** is `webui` (mandatory) **id** is `terminal` (optional) **content** is the command that need to be sent, in our case `[ESP111]` (mandatory) Note: there is no `noDispatch:true` so answer, if any from ESP firmware, will be sent Note 2: there is no way to prevent the answer to be spread if it come from external board from serial, even if `id` and `noDispatch` are set * Answer format: check the `eventMsg.data` - if success ``` { "type": "cmd", "content": { "status": "success" "response": "192.168.1.111", "initiator": { "content":"[ESP111]", "id":"terminal", "target":"webui", "type":"cmd", } }, "id": "terminal" } ``` **type** is `cmd` **id** is the id set in command message to help to screen **content** has the response's **status** which is `success`, the response it self **response**, in our case `192.168.1.111` and also the **initiator** is the initial command for reference -
