Switched map tiles provider from Thunder Forest Outdoors to maptiler.
Much prefer the topographic styling of these maps. They even offer a set of sattelite tiles if I decide I want that option in the future.
Before and after:
.then(() => {
var map = L.map('map');
L.tileLayer('https://tile.thunderforest.com/outdoors/{z}/{x}/{y}.png?apikey=APIKEY', {
maxZoom: 19,
attribution: null
}).addTo(map);
.then(() => {
var map = L.map('map');
L.tileLayer('https://api.maptiler.com/maps/topo-v2/{z}/{x}/{y}.png?key=APIKEY', {
maxZoom: 19,
attribution: null
}).addTo(map);
