deferred-leveldown v7.0.0
deferred-leveldown
A mock
abstract-leveldown
implementation that queues operations while a realabstract-leveldown
instance is being opened.
Usage
If you are upgrading: please see UPGRADING.md.
deferred-leveldown
implements the abstract-leveldown
API so it can be used as a drop-in replacement where leveldown
is needed.
put()
, get()
, getMany()
, del()
, batch()
and clear()
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'))
// Must always call open() first
db.open(function (err) {
// ...
})
// But can operate before open() has finished
db.put('foo', 'bar', function (err) {
// ...
})
