Open Source Software

The following excerpts are the words of our lead developer, Dom.
I created this business and website by myself. However I could never have built this without the countless hours which others poured into the open-source software I used. Some require licenses, some don't, but they all deserve to be listed and given proper attribution.

Svelte
Website: Main Framework

The first on the list for a reason. The rest of the list isn't ordered, but Svelte is arguably the best web framework I've ever worked with. I love Svelte so much. The reason this website loads so fast is in most part thanks to Svelte.

Homepage
Bootstrap
Website: Frontend Styling

I heavily used Bootstrap for front-end formatting to make my website look modern and feel responsive on mobile. This is not my first time using Bootstrap, I've used it for years.

Homepage
Three JS
Website: 3D Viewer

Super popular library for rendering 3D views in the browser. Made rendering the Map Previews a joy. I should also give special thanks to PolyHaven (https://polyhaven.com/) for supplying a beautiful reflective environment texture.

Homepage
Fuse JS
Website: Backend

Super nice library for fuzzy searching. The reason you were able to search for "nsa dioego" and still get "San Diego Intl Airport" as the top result!

Homepage
kd-tree-javascript
Website: Backend

Now we're really getting into the technical weeds. Nice and robust KD-tree library I use for searching through the 2000+ airports.

Homepage
Leaflet
Website: Interactive Map

That interactive map you panned around on is powered by leaflet. It was super easy to implement mapping into my website thanks to Leaflet.

Homepage
Leaflet MarkerCluster
Website: Leaflet Plugin

This plugin is the reason why airports cluster together at higher zoom levels. For showing 2000+ airports at once, that's a must!

Homepage
Leaflet AreaSelect
Website: Leaflet Plugin

*Code modified from original. Super nice lightweight plugin which makes map selection easy.

Homepage
GDAL
Backend: Map Tile Generation

Incredibly helpful geospatial library for warping and converting the FAA's raster charts into map tiles you can easily view on this website.

Homepage
WLED
Backend: Device Software

I absolutely LOVE the WLED project and what they stand for. The reason your map is able to connect to Wi-Fi and request the latest information is because of the WLED software running on all the devices I sell. It's the whole package, which includes the ability for easy updating and easy LED addressing. *Note Lumen's use of an older version of WLED under the MIT license. Thinking of updating soon, but I'm not yet comfortable with open-sourcing my code.
