How to parse a basic array sent through a websocket using JavaScript

Currently, I am working on a project that requires sending simple requests from a Python backend to a JavaScript App. I have an array consisting of names "x", "y", and "z" that I serialize and send over the socket. However, upon receiving it, I am unsure how to parse it into a simple array format instead of JSON format.

Here's an example of what the code should look like:

websocket.onmessage = function(event){
    const receivedMessage = someParses.deserialize(format, event.data);
    console.log(receivedMessage);
}

Answer №1

JSON.parse can handle both JSON objects and arrays

For instance,

jsonString ='{"age":12,"name":"Mrx"}'

JSON.parse(jsonString) => {age: 12, name: "Mrx"}

arrayString ="[12,13]"

JSON.parse(arrayString) => [12,13]

Answer №2

Would you mind sharing the serialize string sample that you're getting in event.data? Different serialization techniques are possible in JavaScript, such as:

JSON.parse( string, modifierfunction ) 

You can then apply a modifier function based on the response you receive.

Answer №3

After utilizing json.dumps() in my Python code to format the array, everything is now functioning properly. Grateful for the assistance.
