Only return short version of sensor UUID in the websocket

[glaslos]

Before publishing to the websockets, truncate the sensor UUID to only the first part until the first -.
Remove truncating from the front-end code.

Hii @glaslos ,
I am exited to work on this issue .
Meanwhile if i run backend server locally what arguments do i need to pass with "go run server.go" to pass token middleware .

[glaslos]

You can just use make or copy the command from here

[Tushar-kalsi]

Can you check if my approach is correct to address this issue .

• Intercept the msg variable from here .
• Decode this msg []byte back to go object by taking reference of Event interface used in frontend .
• Pull out sensorID from this object .
• Alter it according to conditions.
• Convert back into []byte.
• Call cs.publish function .

[glaslos]

Yes, that sound about right. Maybe try without defining the Event type too specific, maybe a map[string]interface{} does the trick here.

Please check if my snippet is correct and let me know how can i test this , i mean how these endpoints will be called when i run locally go server. afterward i will generate PR.

At line

I will put this below snippet in action :

`// Unmarshal the JSON message into a map
var data map[string]interface{}
if err := json.Unmarshal(msg, &data); err != nil {
http.Error(w, "Invalid JSON payload", http.StatusBadRequest)
return
}

// Check if "sensorID" key exists
if sensorID, ok := data["sensorID"].(string); ok {
	// Manipulate the "sensorID"
	sensorID = splitSensorID(sensorID)

	
	// Update the map with the new "sensorID" value
	data["sensorID"] = sensorID
}

// Marshal the map back to a JSON message
alteredMsg , err := json.Marshal(data)
if err != nil {
	http.Error(w, "Error processing JSON", http.StatusInternalServerError)
	return
}



cs.publish(alteredMsg) 

//Helper function which splits into two parts the sensorID by the hyphen
func splitSensorID(sensorID string) string {
parts := strings.Split(sensorID, "-")
if len(parts) > 0 {
return parts[0]
}
return sensorID // Return the original sensorID if there's no hyphen
}`

[glaslos]

Yes, this looks good!

[Tushar-kalsi]

I was curious to know , why havn't we implemented Lint , and designed test cases for both Frontend and backend . Let me if maintainers are looking into this field . I would be happy to implement these .

[glaslos]

I will add linting in the GitHub actions in the future. Considering we are only a few people working in this at the moment, we didn't consider it a priority. Same for the testing, right now we do a lot of manual tests before we release. But feel free to add more tests!
