keyv

Simple Key-Value Storage

Store and retrieve data using simple key-value pairs.

{"const Keyv = require('keyv');
const keyv = new Keyv();
keyv.set('foo', 'bar').then(() => keyv.get('foo').then(value => console.log(value)));
// Logs: 'bar'"}

Namespaces

Use namespaces to avoid key collisions when sharing the same storage backend.

{"const Keyv = require('keyv');
const users = new Keyv('sqlite://path/to/database.sqlite', { namespace: 'users' });
const cache = new Keyv('sqlite://path/to/database.sqlite', { namespace: 'cache' });
// `users` and `cache` can share the same storage without key collisions."}

Support for Multiple Backends

Keyv can be used with various storage backends like Redis, MongoDB, SQLite, and more.

{"const Keyv = require('keyv');
const keyv = new Keyv('redis://user:pass@localhost:6379');
keyv.set('foo', 'bar').then(() => keyv.get('foo').then(value => console.log(value)));
// This will use Redis as the storage backend."}

TTL (Time to Live)

Automatically expire keys after a certain period of time.

{"const Keyv = require('keyv');
const keyv = new Keyv({ ttl: 10000 });
keyv.set('foo', 'expires in 10 seconds', 10000).then(() => setTimeout(() => keyv.get('foo').then(value => console.log(value)), 15000));
// Logs: undefined, since the key has expired after 10 seconds."}
