node-irsdk-mjo v1.0.1

node-irsdk-mjo

Unofficial iRacing SDK implementation for Node.js.

Other iRSDK implementations:

• Official C/C++ SDK
• iRacingSdkWrapper (C#)
• pyirsdk (python3)
• iRacingSDK.Net

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 The original project is no longer maintained and I have made some changes to the code to make it work with the latest version of iRacing.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

  • .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

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();

Development

To develop node-irsdk itself, you need working working installation of node-gyp.

Useful commands:

• npm install builds binary addon
• npm run ready runs tests and updates docs

Making a new release

1. Check if license file needs updating
2. npm run ready
3. Tag new version using npm version, push to Github
4. Wait for Appveyor to upload binaries
5. npm publish
6. Add release notes to Github, helper npm run release-notes.
