# @cistern/consumer

Consumer client for retrieving, decrypting, and deleting Cistern memos.

## Usage

### Generate Keypair

```typescript
import { createConsumer, serializeKey } from "@cistern/consumer";

const consumer = await createConsumer({
  handle: "user.bsky.social",
  appPassword: "xxxx-xxxx-xxxx-xxxx",
});

const keypair = await consumer.generateKeyPair();

console.log(`Public key URI: ${keypair.publicKey}`);
console.log(`Private key: ${serializeKey(keypair.privateKey)}`);
```

### Use Existing Keypair

```typescript
import { createConsumer } from "@cistern/consumer";

const consumer = await createConsumer({
  handle: "user.bsky.social",
  appPassword: "xxxx-xxxx-xxxx-xxxx",
  keypair: {
    publicKey: "at://did:plc:abc123/app.cistern.pubkey/3jzfcijpj2z",
    privateKey: "base64-encoded-private-key",
  },
});
```

### List Memos (Polling)

```typescript
for await (const memo of consumer.listMemos()) {
  console.log(`[${memo.tid}] ${memo.text}`);
  await consumer.deleteMemo(memo.tid);
}
```

### Subscribe to Memos (Real-time)

```typescript
for await (const memo of consumer.subscribeToMemos()) {
  console.log(`[${memo.tid}] ${memo.text}`);
  await consumer.deleteMemo(memo.tid);
}
```
