gun-file v1.0.123

gun-file

A streaming file extension for Gun.

Controlling Options

	var gun = new Gun( { 'file-name' : 'yourData.json',  // default is 'data.json6'
                             'file-mode' : 0666, // default is 0666
                             'file-pretty' : true, // default, if false, will write ugly/compressed json
                             'file-delay' : 100,  // default. control flush interval/delay default.
                           } );

Important

To avoid conflict with Gun's builtin file driver, you will have to use require('gun/gun') plus any other modules you want to use. The option file:null should work in gun to disable the builtin driver, but at this point does not.

var Gun = require( "gun/gun" );
require( 'gun-file' );
