node-irsdk-mjo

Unofficial iRacing SDK implementation for Node.js.

Other iRSDK implementations:

Disclaimer

This is a fork of node-irsdk by apihlaja. The original project is no longer maintained and I have made some changes to the code to make it work with the latest version of iRacing.

Pre-requisites

For compiling this package you need node-gyp@^9.0.0.

npm install -g node-gyp

You also need a current version of Python3 and Microsoft Visual Studio Build Tools installed. More information regarding the topic can be found here. I haven't tried this myself (as I already had msbuild installed), but according to the documentation, you could easily run:

npm install -g windows-build-tools

Installing

Make sure you have Node.js v19 x64 or later.

npm install --save node-irsdk-mjo

irsdk
- .init([opts]) ⇒ iracing
- .getInstance() ⇒ iracing

irsdk.init([opts]) ⇒ iracing

Initialize JsIrSdk, can be done once before using getInstance first time.

Kind: static method of irsdk
Returns: iracing - Running instance of JsIrSdk

| Param | Type | Default | Description | | -------------------------------- | ------------------------------------------------------------- | -------------- | ----------------------------------------- | | [opts] | Object | | Options | | [opts.telemetryUpdateInterval] | Integer | 0 | Telemetry update interval, milliseconds | | [opts.sessionInfoUpdateInterval] | Integer | 0 | SessionInfo update interval, milliseconds | | [opts.sessionInfoParser] | sessionInfoParser | | Custom parser for session info |

var irsdk = require("node-irsdk");
// look for telemetry updates only once per 100 ms
var iracing = irsdk.init({ telemetryUpdateInterval: 100 });

irsdk.getInstance() ⇒ iracing

Get initialized instance of JsIrSdk

Kind: static method of irsdk
Returns: iracing - Running instance of JsIrSdk

var irsdk = require("node-irsdk");
var iracing = irsdk.getInstance();

iracing ⇐ events.EventEmitter

Kind: global class
Extends: events.EventEmitter
Emits: Connected, Disconnected, Telemetry, TelemetryDescription, SessionInfo
See: EventEmitter API

iracing ⇐ events.EventEmitter

new JsIrSdk()

JsIrSdk is javascript implementation of iRacing SDK.
