The readJson function returns a promise that resolves with the JSON object parsed from the file.

You can also pass options to the readJson function to customize the JSON parsing behavior. Some of the available options are:

• throws (boolean): If set to true, an error will be thrown when parsing fails (default: true)
• reviver (function): Prescribes how the value originally produced by parsing JSON should be transformed, before being returned.
• encoding (string): The file encoding (default: 'utf8')
• flag (string): The file system flag (default: 'r')

index.tsx
const options = {
  throws: false,
  reviver: (key, value) => {},
  encoding: 'utf8',
  flag: 'r'
};

fs.readJson(filePath, options)
  .then(data => {
    console.log(data);
  })
  .catch(err => {
    console.error(err);
  });
