How does fs-extra.writeJSON work?

fs-extra.writeJSON is a method in the fs-extra library that allows you to write a JSON object to a file on disk. It takes two parameters: the file path and the JSON object to write. When you call fs-extra.writeJSON, it creates a new file or overwrites the contents of an existing file with the specified JSON object. The JSON object is converted to a string and written to the file using the fs-extra.writeFile method. By default, fs-extra.writeJSON will use two-space indentation when formatting the JSON output. However, you can customize this behavior by passing an optional third parameter, which is an options object that allows you to specify the number of spaces to use for indentation and other formatting options. If an error occurs while writing the JSON object to the file, fs-extra.writeJSON will throw an exception. You can handle this exception by wrapping your call to fs-extra.writeJSON in a try-catch block or using a promise-based approach.

const fs = require("fs-extra");

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

// Write the data to a JSON file named 'data.json' in the current directory
fs.writeJSON("data.json", data)
  .then(() => console.log("Data written to file"))
  .catch((err) => console.error(err));

This example creates an object called data with properties for a person's name, age, and email. The fs-extra.writeJSON method is then used to write this object to a file named data.json in the current directory. The method returns a promise, so the example uses .then() and .catch() to handle success and error cases respectively. If the file is successfully written, the message "Data written to file" will be logged to the console. If an error occurs, the error object will be logged to the console.
