What is fs-exists-cached?

The fs-exists-cached npm package provides a simple and efficient way to check if a file or directory exists, with caching to improve performance for repeated checks.

What are fs-exists-cached's main functionalities?

Check if a file or directory exists

This feature allows you to check if a specified file or directory exists. The result is cached to improve performance for subsequent checks.

const fsExistsCached = require('fs-exists-cached');

fsExistsCached('path/to/file/or/directory').then(exists => {
  console.log(exists ? 'Exists' : 'Does not exist');
});

Synchronous check if a file or directory exists

This feature provides a synchronous method to check if a specified file or directory exists. The result is cached for performance optimization.

const fsExistsCached = require('fs-exists-cached');

const exists = fsExistsCached.sync('path/to/file/or/directory');
console.log(exists ? 'Exists' : 'Does not exist');
