Contributing to God's Eye View

Thanks for being here. God's Eye View is an open foundation for live spatial intelligence in the browser, and it gets better when more people run it, break it, and extend it.

Getting set up

Use Node.js 24.14.x or 26.x (also enforced by package.json).

git clone https://github.com/bilawalsidhu/gods-eye-view.git
cd gods-eye-view
nvm install 24.14.0
nvm use 24.14.0
npm install
npm run doctor
./scripts/dev-fresh.sh        # or: npm run dev (keys are optional)

No key is required to start: the app boots on keyless Esri World Imagery with keyless terrain, and OSM takes over automatically if Esri is unreachable. Google Maps provides direct photorealistic 3D and place search; Cesium ion provides ion-hosted Google 3D plus optional Bing/world-terrain stacks. On macOS the launcher pulls optional keys from the Keychain; on any platform you can pass them as env vars or use a .env. People who only want to run the app can instead install the repository directly through Pinokio; the terminal path above remains the contributor path.

Open http://localhost:4173. Before sending a PR run npm run build, npm test, and npm run test:track (dev server must be up) — all three must stay green.

Good first contributions

The highest-leverage places to jump in:

🌆 Add a CCTV source pack. Austin is the reference camera source. Adding another city means a clean public camera catalog with coordinates, attribution, and server-registered frame URLs (the proxy only fetches registered URLs — never client-supplied ones, see SECURITY.md). City packs are the best first lane.
🛰️ Add or improve a data layer. Each layer is one self-contained module in src/data/<layer>.js implementing the layer interface (init/enable/disable/update/destroy/getStats, optional getDetectableObjects/getStats). Use an existing layer as a template.
🎙️ Extend voice control. Voice tools are declared server-side (GEV_REALTIME_TOOLS in vite.config.js) and executed client-side (src/voice/gevActions.js). Keep the tool surface tight and the responses honest (confirm only what actually happened).
🎨 Add a visual style. Styles are GLSL post-process shaders in src/styles/.
🐛 Fix bugs / improve the first-run experience. See docs/KNOWN-ISSUES.md.

Architecture in one minute

No framework. Vanilla JS + CesiumJS + Vite.
UI lives in src/ui.js (panels, HUD, styles, the control facade). Layer logic lives in src/data/<layer>.js. Keep them separate.
Secrets stay server-side. Anything needing a private key goes through a Vite proxy in vite.config.js. The browser only ever sees the Google Maps key (which you restrict) and ephemeral tokens.
docs/CURRENT-STATE.md is the authoritative runtime reference — read it first.

Coding style

ES modules, 2-space indent, single quotes, semicolons.
JSDoc on exported/public functions.
Match the surrounding code — comment density, naming, and idiom.
Prefer small, reviewable commits. Conventional-commit-style prefixes (feat:, fix:, perf:, docs:) are appreciated but not required.

Pull requests

Branch off main.
Keep npm run build, npm test, and npm run test:track green and avoid new console errors.
If you change runtime behavior, update docs/CURRENT-STATE.md and CHANGELOG.md in the same PR.
If you add or change a data source, update DATA_SOURCES.md with its license and attribution. Don't add data you don't have the right to redistribute — fetch it at runtime instead.
Describe what you changed and how you verified it (screenshots welcome for anything visual).

Ground rules

This is a tool for public data. Don't add scraping of sources whose terms forbid it, private/paywalled datasets, or anything that misrepresents public-data inference as authoritative intelligence.
Be decent to each other. Assume good faith, keep it constructive.
