This is a basic mapbox map hosted at caseymm.github.io/mbx-devour. The map is set up to display geojson passed to it through the url search parameters.
url(geojson must be hosted somewhere, you cannot pass in raw geojson, e.g. https://weather-warnings.s3.us-west-1.amazonaws.com/rfw/latest.json)fill(do not include #, e.g. ff0080)fill opacity(e.g. .5)
An example url would be built like this:
https://caseymm.github.io/mbx-devour/?url=[your url]&fill=[your color]&fill-opacity=[your opacity]
That example would render this on the map:

- build:
npm run build - add, commit, push
- deploy:
npm run deploy
