RSocketTcpClient不是带有Rsocket-js的构造函数- NodeJS。

Question

我想使用Rsocket (https://rsocket.io/guides/rsocket-js/client/rsocket-tcp-client)中的简单示例在NodeJs上运行Rsocket客户端：

async function createClient(options) {
  const client = new RSocketClient({
    setup: {
      dataMimeType: 'text/plain',
      keepAlive: 1000000, // avoid sending during test
      lifetime: 100000,
      metadataMimeType: 'text/plain',
    },
    transport: new RSocketTCPClient({
      host: options.host,
      port: options.port,
    }),
  });

  return await client.connect();
}

async function run() {
  const rsocket = await createClient({
    host: '127.0.0.1',
    port: 9898,
  });
}

await run();

但是当我试图用node app.js运行应用程序时，会出现一个错误：TypeError: RSocketTcpClient is not a constructor。我检查了RSocketTcpClient的实现，它看起来有构造函数：

export class RSocketTcpClient extends RSocketTcpConnection {
  constructor(options: net.TcpSocketConnectOpts, encoders?: Encoders<any>);
  connect(): void;
}

有人能告诉我怎么回事吗？我使用的是简单的package.json：

{
  "name": "rsocket-example",
  "private": true,
  "description": "RSocket example",
  "version": "0.0.27",
  "repository": {
    "type": "git",
    "url": "https://github.com/rsocket/rsocket-js.git"
  },
  "type": "module",
  "dependencies": {
    "rsocket-core": "^0.0.27",
    "rsocket-flowable": "^0.0.27",
    "rsocket-tcp-server": "^0.0.27",
    "rsocket-types": "^0.0.27",
    "rsocket-websocket-client": "^0.0.27",
    "rsocket-websocket-server": "^0.0.27"
  }
}

这里的源项目https://rsocket.io/guides/rsocket-js/似乎配置错误，将RSocketTCPClient类声明的默认导出置于default变量下。

然后，您可以在自己的项目中调整转换程序配置，或者只使用default导出对象，如下所示：

// instead of new RSocketTCPClient()
new RSocketTCPClient.default({
    host: options.host,
    port: options.port,
});
