How does fs-extra.writeSync work?

fs-extra.writeSync is a method in the fs-extra library that writes data to a file synchronously. It takes three parameters: the file path, the data to write, and an optional encoding (default is utf8). The method will overwrite the existing file if it already exists, or create a new file if it doesn't exist. The method works by first opening the file using the given file path and encoding. It then writes the data to the file and closes it. If there is an error during the process, the method will throw an error. Since fs-extra.writeSync is a synchronous method, it will block the execution of the program until the writing operation is completed. This means that the method is not suitable for large files or for applications that require high performance, as it may cause the program to slow down or become unresponsive. In such cases, it is recommended to use the asynchronous fs-extra.writeFile method instead.

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

const filePath = "example.txt";
const data = "Hello, world!";

try {
  fs.writeSync(filePath, data);
  console.log("Data written to file synchronously.");
} catch (err) {
  console.error(err);
}

In this example, the fs-extra.writeSync method is used to write the string 'Hello, world!' to a file named example.txt synchronously. The method is wrapped in a try-catch block to handle any errors that might occur during the writing operation. If the write operation is successful, the console will log the message 'Data written to file synchronously.'.
