deferred-leveldown

A mock abstract-leveldown implementation that queues operations while a real abstract-leveldown instance is being opened.

level badge npm Node version Build Status david JavaScript Style Guide npm

deferred-leveldown implements the basic abstract-leveldown API so it can be used as a drop-in replacement where leveldown is needed.

put(), get(), del() and batch() operations are all queued and kept in memory until the abstract-leveldown-compatible object has been opened through deferred-leveldown's open() method.

batch() operations will all be replayed as the array form. Chained-batch operations are converted before being stored.

const deferred  = require('deferred-leveldown')
const leveldown = require('leveldown')
 
const db = deferred(leveldown('location'))
 
db.put('foo', 'bar', function (err) {
 
})
 
db.open(function (err) {
  // ...
})
