Fetching new track SVG paths

Script downloads track maps from iracing API and saves them into a static file. Generally it should be used when new tracks are released.

Set environment variables:

$env:IRACING_LOGIN = '<iracing login>'
$env:IRACING_PWD = '<iracing password>'

Run script via pnpm:

pnpm run fetch-track-info

Script will report its progress and final state upon finish.

Track info (with main track paths) will be saved to track_info.json.

Track start/finish SVGs will be saved to start_finish directory

Track settings

Iracing's SVG start point and direction may differ with start/finish line and track direction. To overcome this issue one can manually fill in track_settings.json static file. It stores a json object where keys are track ids and values have the following format:

{
    "offset": 0.567,
    "direction": -1
}

offset is a start/finish line offset from SVG starting point (value shoud be between 0 and 1), direction is 1 if track direction matches SVG path direction and -1 otherwise.

To search for these values you can use accompanying interface located at /track_info url when lauching iRaceHUD via Vite development mode.
