NDK

Appearance

Storage Options ​

To make sure NDK persists sessions, you need to provide one of the following storage options.

Local Storage ​

Suited for browser/web-app applications.

typescript
import { LocalStorage } from '@nostr-dev-kit/sessions';

const sessions = new NDKSessionManager(ndk, {
  storage: new LocalStorage('my-app-sessions') // Custom key
});

File Storage ​

Common used for NodeJS application or CLI scripts.

typescript
import { FileStorage } from '@nostr-dev-kit/sessions';

const sessions = new NDKSessionManager(ndk, {
  storage: new FileStorage('./.ndk-sessions.json')
});

Memory Storage ​

Temporary, mostly used for testing or short lived application logic.

typescript
import { MemoryStorage } from '@nostr-dev-kit/sessions';

const sessions = new NDKSessionManager(ndk, {
  storage: new MemoryStorage(), // No persistence
  autoSave: false
});
