simple-exist

Simple functions to check if a file exists both synchronously and asynchronously.

Install

Use your favourite Node.js package manager:

yarn add simple-exist
npm install simple-exist

Usage

exists(file, callback)

Works asynchronously. Pass in a filename as a string and get either true or false as a callback argument.

Example

const exists = require('simple-exist').exists;

exists('file', res => {
  if (res) {
    // File exists
  } else {
    // File does not exist
  }
});

existsSync(file)

Works synchronously. Pass in the filename as a string. The function will return either true or false.

Note: Node.js' fs.existsSync is no longer deprecated, and you should use that instead. This function has been kept in this module for backwards compatability.

Example

const exists = require('simple-exist').existsSync;

if (existsSync('file')) {
  // File exists
} else {
  // File does not exist
}

Testing

To run tests, install development dependencies (yarn -D, npm i -D) and run the test script (yarn run test, npm run test).
