File Methods

• exists
• create
• remove

file exists

exists(file)

Check if a file exists. Promise returns true or false whether the file exists or not.

Example:

const io = require('io-extra');

io.file.exists('/tmp/myfile').then((exists) => console.log('file exists: ' + exists));

create file

create(file)

Creates a file if it doesn't already exists. Promise returns the full path of the created file.

Example:

const io = require('io-extra');

io.file.exists('/tmp/myfile').then((file) => console.log('file ' + file + ' created.'));

remove file

remove(file)

Removes a file if it exists. Empty promise is returned.

Example:

const io = require('io-extra');

io.file.remove('/tmp/myfile').then(() => console.log('file removed.'));
