Node.js Twitter WebSocket Client

Build a Node.js client for TweetStream's Twitter/X WebSocket API with API-key subprotocol auth and production reconnect handling.

Direct answer

A Node.js TweetStream client opens a WebSocket with API-key subprotocol auth, parses JSON envelopes, and reconnects safely.

Connection details

Keep the API key in environment variables and connect from a server process.

  • wss://ws.tweetstream.io/ws
  • tweetstream.v1
  • tweetstream.auth.token.<API_KEY>

Reconnect strategy

Production clients should treat reconnects as normal. Keep event handling idempotent and make sure duplicate messages do not trigger duplicate trades or alerts.

Implementation asset: adaptable code example

Use this Node-oriented handler shape after parsing TweetStream WebSocket messages. Adapt the terms, tracked accounts, and destination to your own routing rules.

const watchTerms = ["token", "listing", "contract", "airdrop"];
const destination = "node-worker";

export function routeNodeClientEvent(event: {
  d?: {
    author?: string;
    detected?: { tokens?: Array<unknown> };
    ocr?: string;
    text?: string;
  };
}) {
  const text = `${event.d?.text ?? ""} ${event.d?.ocr ?? ""}`.toLowerCase();
  const matchedTerm = watchTerms.find((term) => text.includes(term.toLowerCase()));
  const hasTokenSignal = Boolean(event.d?.detected?.tokens?.length);

  return {
    author: event.d?.author,
    deliver: Boolean(matchedTerm || hasTokenSignal),
    destination,
    matchedTerm,
  };
}

Why implement this with TweetStream

You can build this workflow from raw APIs, polling, and custom scraping, but TweetStream is the better starting point when speed, structured payloads, token/OCR enrichment, and reliable WebSocket delivery matter.
