F1 Telemetry Client

The F1 series of games support the outputting of key game data via a UDP data stream. This data can be interpreted by external apps or connected peripherals for a range of different uses, including providing additional telemetry information, customised HUD displays, motion platform hardware support or providing force feedback data for custom steering wheels.

This is a TypeScript UDP client and telemetry parser for EA - Codemaster's F1 22, F1 2021, F1 2020, F1 2019 and F1 2018, that enables the consumption of such information.


$ npm install @racehub-io/f1-telemetry-client


$ yarn add @racehub-io/f1-telemetry-client

Running the playground

$ npm run start


$ yarn start


import { F1TelemetryClient, constants } from "f1-telemetry-client";
// or: const { F1TelemetryClient, constants } = require('f1-telemetry-client');
const { PACKETS } = constants;

*   'port' is optional, defaults to 20777
*   'bigintEnabled' is optional, setting it to false makes the parser skip bigint values,
*                   defaults to true
*   'forwardAddresses' is optional, it's an array of Address objects to forward unparsed telemetry to. each address object is comprised of a port and an optional ip address
*                   defaults to undefined
*   'skipParsing' is optional, setting it to true will make the client not parse and emit content. You can consume telemetry data using forwardAddresses instead.
*                   defaults to false
const client = new F1TelemetryClient({ port: 20777 });
