npm install fs-extra

After installing the package, you can use the readJsonSync() function to read a JSON file synchronously. Here's an example:

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

try {
  const jsonData = fs.readJsonSync('path/to/jsonfile.json');
  console.log(jsonData);
} catch (err) {
  console.error(err);
}

In the example above, fs.readJsonSync() reads the data from the JSON file at 'path/to/jsonfile.json' and returns a JavaScript object. This object is then logged to the console.

If an error occurs while reading the file, the try...catch block catches it and logs it to the console using console.error().
