The RMB Peer Client is a TypeScript library that enables communication with the ThreeFold Messaging Bus (RMB). It provides functionalities similar to the Rust client.
To use the RMB Peer Client, instantiate the MessageBusClient
class:
import { MessageBusClient } from "@threefold/rmb_peer_client";
const messageBus = new MessageBusClient();
You can send messages over the RMB using the send
method, which takes the following parameters:
requestCommand
The command to be executed in the Zero-OS node.requestData
The message content.destinationTwinId
The ID of the destination twin to receive the message.expirationMinutes
Expiration time for the message in minutes.
const requestId = await messageBus.send("zos.nodes.list", "", 143, 5);
After sending a message, you can read the response using the read
method:
const response = await messageBus.read(requestId);
Install the package via npm:
npm install @threefold/rmb_peer_client
import { MessageBusClient } from "@threefold/rmb_peer_client";
const messageBus = new MessageBusClient();
// Send a message
const requestId = await messageBus.send("zos.nodes.list", "", 143, 5);
// Read the response
const response = await messageBus.read(requestId);
- Constructor function to create a new instance of the RMB Peer Client.
- Accepts an optional

parameter to specify the Redis server port. Defaults to6379
.
