How does fs-extra.write work?

fs-extra.write is a function that writes data to a file, creating the file if it doesn't exist or overwriting its contents if it does. The function takes two arguments: the path of the file to be written, and the data to write to the file. The path argument can be either a string or a Buffer, and the data argument can be a string, a Buffer, or an object that will be converted to a JSON string before being written to the file. By default, fs-extra.write writes data to a file synchronously. If you need to write data asynchronously, you can use fs-extra.writeFile instead. If the file already exists, fs-extra.write overwrites its contents with the new data. If the file does not exist, the function creates a new file and writes the data to it. fs-extra.write automatically creates any parent directories that don't exist, so you don't need to create the directory manually before calling the function. Overall, fs-extra.write provides a convenient and reliable way to write data to a file, with the added benefit of automatically creating any necessary directories.

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

const filePath = "/path/to/file.txt";
const data = "Hello, world!";

fs.write(filePath, data)
  .then(() => {
    console.log("Data written to file");
  })
  .catch((err) => {
    console.error(err);
  });

In this example, we first import the fs-extra library, which provides the write function. We then define a file path '/path/to/file.txt' and some data 'Hello, world!' that we want to write to the file. We call the fs.write function with the file path and data as arguments. The function returns a Promise that resolves when the data has been written to the file. In the .then callback, we log a message to the console indicating that the data was successfully written to the file. In the .catch callback, we log any errors that occurred while writing the data. By using fs-extra.write to write data to a file, we ensure that the file is created if it doesn't already exist, and that its contents are overwritten with the new data.
