One Night on Earth is written in Typescript and Zig.

## Controls

The controls currently available on the site are:

1. Change Date - Update the date that the sky is simulated for

2. Change Location - Enter a new latitude and/or longitude, then click 'Update Location' to move the simulation to the desired coordinates.

3. 'Use My Location' - Navigate to your current location.

4. 'Time Travel' - Click this button to start automatically advancing the date. Click again to stop.

5. Drag and Move - Click and drag on the map to move the sky. Your updated coordinates will be populated in the 'Latitude' and 'Longitude' fields.

6. Zoom - Scroll with your mouse while hovering over the map to zoom in/out.

## Running Locally

There are a few steps to get started:

**Pre-Requisites**

- Zig - See [Zig on GitHub](https://github.com/ziglang/zig) for more instructions.

- Node - See https://nodejs.org/en/download/

**On First Run Only:**

1. Run `cd web && npm install`

2. Run `cd prepare-data && zig build run -Drelease-fast -- ../zig-server/star_data.bin ../zig-server/const_data.bin ../zig-server/const_meta.json`. This will create all of the data files that the server needs in order to run.

**Each Run:**

1. In one terminal, run `cd zig-server && zig build run`.

2. Run `cd night-math && zig build -Drelease-fast`. This will create the WASM module as well as the module TS interfaces.

3. In another terminal, run `cd web && npm start`.

Now you're ready! Like before, visit `localhost:8080` to view the site.
