How does jsonfile.writeFile work?

jsonfile.writeFile() is a function from the jsonfile library in Node.js used to write JSON data to a file on disk with optional formatting and error handling capabilities. It takes three arguments: the path to the file to be written, the JSON data to be written, and an optional configuration object with options such as indentation level and error handling behavior. When the function is called, it will first convert the JSON data to a string, then write the string to the specified file. If the file does not exist, it will be created. If an error occurs during the write process, the function will either throw an error or call a callback function provided in the configuration object, depending on the error handling behavior specified.

const jsonfile = require("jsonfile");

const data = {
  name: "John Doe",
  age: 30,
  email: "johndoe@example.com",
};

jsonfile.writeFile("data.json", data, (err) => {
  if (err) {
    console.error(err);
  } else {
    console.log("Data saved to file");
  }
});

In this example, we have an object data that we want to write to a file named data.json. We pass the file name and the data to jsonfile.writeFile. The function takes a callback as its third argument, which is called when the file has been written. If there was an error, it will be passed as the first argument to the callback; otherwise, the callback will be called with no arguments.
