leaflet map shows up grey

Question

I\'m starting leaflet.js with the quickstart but my map shows as grey... is there something I\'m missing?

script.js:

var leafletMap = L.map(\'leaflet         


        

Answer 1

Did you set a value for API_KEY in your code?

When I first ran the quickstart I was also confused why my map was grey, but I just realised I'd forgotten to retrieve an API access code (in my case, it was for Mapbox's service.)

Your URL line references API_KEY but you don't seem to be declaring it.
