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

$3

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
}
});
`

$3

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`).
