将字符串消息拆分为 Typescript 中的数组

Question

I'm trying to split a string message into array in Typescript. I cannot use comma as there's a json string. I tried to parse but I'm getting an error.

const msgs = 'string_no_quotes,"string-with@}-weirdchars",{"ckey":null,"email":"user@gmail.com","pass":"password","name":{"firstName":"User","middleName":"","lastName":"Name"},"address":{"street": "test street", "country":"some country", "zip": "639821"},"status":1},opt-data'

const messages:string[] = JSON.parse(msgs.toString())

The error :

SyntaxError: Unexpected token c in JSON at position 1
    at JSON.parse (<anonymous>)

What could be a best solution to get values in to string array.

PS: If you wonder why I came up with such nasty string, its 'ZeroMQ' message. And, i tried,

JSON.parse("["+msgs.toString()+"]")
eval("("+msgs.toString()+")")

Got it figured out with a custom func after a long tryout, not a straight forward, but works as needed. The original problem was the input is received as a buffer from zmq broker and there's that weird format of data from msg.toString()

Steps:

1. Used a regex to segregate the object data,

2. replace the regex match with template string,

3. split it, replace the 'made' array and return it.

    export const parseTheCrapOutOfThatDamnString = (paramString: string) => { const regEx = RegExp("(?<={)(.*)(?=})") //(?<={)(.*)(?=}) //https://regexr.com/2tr5t if(regEx.test(paramString)) { var theMatch:string = `${_.head(paramString.match(regEx))}` || "" //;console.log(`\\n${theMatch}\\n`) var paramsArray = _.replace(paramString, theMatch, "replaceable").split(',') //;console.log(paramString) paramsArray[paramsArray.indexOf('{replaceable}')] = JSON.parse(`{${theMatch}}`) return paramsArray; }else { return JSON.parse("["+paramString+"]") } }

the call,

  const msgs = 'string_no_quotes,"string-with@}-weirdchars",{"ckey":null,"email":"user@gmail.com","pass":"password","name":{"firstName":"User","middleName":"","lastName":"Name"},"address":{"street": "test street", "country":"some country", "zip": "639821"},"status":1},opt-data'
  console.log(parseTheCrapOutOfThatDamnString(msgs))

the final output:

["string_no_quotes", "string-with@}-weirdchars", {
  "ckey": null,
  "email": "user@gmail.com",
  "pass": "password",
  "name": {
    "firstName": "User",
    "middleName": "",
    "lastName": "Name"
  },
  "address": {
    "street": "test street",
    "country": "some country",
    "zip": "639821"
  },
  "status": 1
}, "opt-data"]

here it is Typescript play
