getFragmentSize

The getFragmentSize method is used to specify a maximum size for each WebSocket message fragment sent by the Durable Object.

getFragmentSize(): undefined | number

Return a number to split larger synchronization payloads into fragments that are reassembled by the receiving WsSynchronizer. Return undefined to send each payload as a single WebSocket message.

import {WsServerDurableObject} from 'tinybase/synchronizers/synchronizer-ws-server-durable-object';

export class MyDurableObject extends WsServerDurableObject {
  getFragmentSize() {
    return 32 * 1024;
  }
}
