Storage
A storage plugin is a database that stores zone data. The main Store interface is backend agnostic — stores can be backed by durable data written to disk, a database engine, or even ephemeral, in-memory structures. The DefaultStore, for example, is a simple in-memory implementation.
Stores are generally expected to allow for direct lookups and wildcard lookups. They should implement the matching behavior described by RFC 1034. Likewise, they should implement interfaces to retrieve all the data for a particular zone, or just one record. Most stores should also implement methods to manipulate zone data; the interface supports methods to get, set, append, and delete zone data.
const store = new DefaultStore();
store.set('example.com', 'A', '127.0.0.1');
store.append('example.com', 'A', '127.0.0.2');
store.delete('example.com', 'A', '127.0.0.1');
store.get('example.com', 'A'); // ['127.0.0.2']
store.delete('example.com', 'A');
store.delete('example.com');
store.get('example.com', 'A') // null
