Concatenate entries from an iterator into an array.
📌 This module will soon be deprecated, because its functionality is included in
abstract-level.
const concat = require('level-concat-iterator')
const level = require('level')
const db = level('./db')
db.put('foo', 'bar', function (err) {
if (err) throw err
concat(db.iterator(), function (err, entries) {
if (err) throw err
// [{ key: 'foo', value: 'bar' }]
console.log(entries)
})
})With promises:
await db.put('foo', 'bar')
const entries = await concat(db.iterator())If you are upgrading: please see UPGRADING.md.
Takes an abstract-leveldown compatible iterator as first parameter and calls the callback with an array of entries, where each entry is an object in the form { key, value }. Calls the callback with an error if iterator.next() or iterator.end() errors. If no callback is provided, a promise is returned.
Level/concat-iterator 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.
