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) {
// ...
})Level/deferred-leveldown is an OPEN Open Source Project. This means that:
Individuals making significant and valuable contributions are given commit-access to the project to contribute as they see fit. This project is more like an open wiki than a standard guarded open source project.
