Lazily open a leveldown compatible backend.

NOTE: This doesn't work with levelup. This can only be useful to you if you're using leveldown directly.

Example

var lazy = require('level-lazy-open');
var down = require('leveldown');

// a function that returns an open backend
function factory(cb){
  var db = down('./db');
  db.open(function(err){
    cb(err, db);
  });
}

var db = lazy(factory);

// db is closed and won't be opened, unless
// you do something with it:

db.put('foo', 'bar', function(err){
  // db is open now

  // you can manually close the db again:
  db.close(function(err){
    // the end
  });
});
// db is opening now

Installation

$ npm install level-lazy-open

API

lazy(factory)

Create a new abstract-leveldown compatible db that calls factory to get a db whenever it hasn't yet and you perform an operation against it.
