Transform the string response in a websocket message into JSON format

When receiving a websocket message, I often encounter a response in the form of a string like this:

odds.1:[{"id":1,"marketType":10,"name":"Double chance","status":"HandedOver","specifiers":"","Outcomes":[]},{"id":2,"marketType":11,"name":"Draw no bet","status":"HandedOver","specifiers":"","Outcomes":[]},{"id":3,"marketType":1,"name":"1x2","status":"HandedOver","specifiers":"","Outcomes":[]}]

I am looking to parse this as a JSON array, but I am uncertain about the correct method...

(please note that I also need to remove 'odds.1' from the string)

Here are some methods I have attempted, but they did not yield the expected results:

  1. message.json()
  2. JSON.stringify(message)
  3. JSON.parse(message)

Answer №1

If you're looking for a fast solution, consider the following:

const data = `odds.1:[{"id":1,"marketType":10,"name":"Double chance","status":"HandedOver","specifiers":"","Outcomes":[]},{"id":2,"marketType":11,"name":"Draw no bet","status":"HandedOver","specifiers":"","Outcomes":[]},{"id":3,"marketType":1,"name":"1x2","status":"HandedOver","specifiers":"","Outcomes":[]}]`;

const dataArray = data.split("odds.1:")[1];
const parsedData = JSON.parse(dataArray);
console.log(parsedData);

Answer №2

The JSON format of your string is incorrect. It should be enclosed within curly braces {} and the key "odds .1" must be enclosed in double quotes as shown below:

{
    "odds .1": [{
        "id": 1,
        "marketType": 10,
        "name": "Double chance",
        "status": "HandedOver",
        "specifiers": "",
        "Outcomes": []
    }, {
        "id": 2,
        "marketType": 11,
        "name": "Draw no bet",
        "status": "HandedOver",
        "specifiers": "",
        "Outcomes": []
    }, {
        "id": 3,
        "marketType": 1,
        "name": "1x2",
        "status": "HandedOver",
        "specifiers": "",
        "Outcomes": []
    }]
}
