I would like to run Rsocket TCP client on NodeJs using simple example from Rsocket guide(https://rsocket.io/guides/rsocket-js/client/rsocket-tcp-client):
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();
but when I am trying to run app by node app.js
there is an error:
TypeError: RSocketTcpClient is not a constructor
.
I've checked implementation of RSocketTcpClient
, and it looks like there is constructor:
export class RSocketTcpClient extends RSocketTcpConnection {
constructor(options: net.TcpSocketConnectOpts, encoders?: Encoders<any>);
connect(): void;
}
Could anyone tell me what is wrong? I am using simple 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"
}
}
The source project, rsocket-js in here, seems to have transpiration misconfigured letting the default export for the RSocketTCPClient
class declaration go under a default
variable.
You workaround would then either to tweak the transpiler configuration in your own project or use just the default
exported object as follows:
// instead of new RSocketTCPClient()
new RSocketTCPClient.default({
host: options.host,
port: options.port,
});
