F1 Telemetry Client

Known Vulnerabilities

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 Codemaster's F1 2019 and F1 2018 games that enables the consumption of such information.


$ npm install f1-telemetry-client


$ yarn add 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;

const client = new F1TelemetryClient();
client.on(PACKETS.session, console.log);
client.on(PACKETS.motion, console.log);
client.on(PACKETS.lapData, console.log);
client.on(PACKETS.event, console.log);
client.on(PACKETS.participants, console.log);
client.on(PACKETS.carSetups, console.log);
client.on(PACKETS.carTelemetry, console.log);
client.on(PACKETS.carStatus, console.log);
