Solution

Your problem is unclear, are you struggling with

1. Reading the file?
2. Parsing and manipulating the JSON?
3. Saving the file?

Anyways, this code might help you:

const fs = require("fs");

fs.readFile("./test.json", (err, data) => {
  let json = JSON.parse(data.toString());

  // shift() removes the first object in 'auth'. Manipulate json however you wish.
  json["auth"].shift();

  // Remove second object (as asked by OP)
  json["auth"].pop();

  fs.writeFile("./test.json", JSON.stringify(json), function (err) {
    if (err) {
      return console.log(err);
    }
    console.log("The file was saved!");
  });
});

It first reads the file, parses the contents into JSON. Then manipulates the JSON, and then saves the file, and will console.log("The file was saved!"); if successful.
