npm Node output steam to pretty json to terminal

Question

I want to be able to stream all the output data from when I run npm run start into pretty JSON. The issue when using jq is that some output is not JSON is there any way to pretty-print JSON from an output stream where sometimes its text and sometimes it's JSON

Example id like

[nodemon] 1.19.4
[nodemon] to restart at any time, enter `rs`
[nodemon] watching dir(s): src/**/*
[nodemon] watching extensions: ts
[nodemon] starting `ts-node ./src/index.ts index.js`
helmet deprecated helmet.noCache is deprecated and will be removed in [11:11:55] Found 0 errors. Watching for file changes.

[{"caller": "RESOURCE ACCESS","token": "","msg": "xxx","statusCode": null,"level": "info","time": "xxx"},{"endpoint": "some endpoint","msg": "Initial endpoint","data": {"campaign_id": "xxx"},"level": "info","time": "xxx"},{"msg": "Request received","endpoint": "some other endpoint","method": "GET"}]

To be formatted in the terminal like

[nodemon] 1.19.4
[nodemon] to restart at any time, enter `rs`
[nodemon] watching dir(s): src/**/*
[nodemon] watching extensions: ts
[nodemon] starting `ts-node ./src/index.ts index.js`
helmet deprecated helmet.noCache is deprecated and will be removed in [11:11:55] Found 0 errors. Watching for file changes.

[
  {
    "caller": "RESOURCE ACCESS",
    "token": "",
    "msg": "xxx",
    "statusCode": null,
    "level": "info",
    "time": "xxx"
  },
  {
    "endpoint": "some endpoint",
    "msg": "Initial endpoint",
    "data": {
      "campaign_id": "xxx"
    },
    "level": "info",
    "time": "xxx"
  },
  {
    "msg": "Request received",
    "endpoint": "some other endpoint",
    "method": "GET"
  }
