Use the exists function to check whether a file or directory exists:


index.tsx
// Check if file exists
fs.pathExists('/path/to/file')
  .then(exists => console.log(exists))
  .catch(err => console.error(err))

// Check if directory exists
fs.pathExists('/path/to/directory')
  .then(exists => console.log(exists))
  .catch(err => console.error(err))

The exists function returns a promise that resolves to a boolean value indicating whether the specified file or directory exists or not. If the specified file or directory exists, the promise resolves to true, otherwise it resolves to false.

Note that you can also use the exists function synchronously if you don’t need a promise:


index.tsx
// Check if file exists synchronously
const exists = fs.existsSync('/path/to/file');
console.log(exists);

// Check if directory exists synchronously
const exists = fs.existsSync('/path/to/directory');
console.log(exists);
