Right now I have a GeoJSON hosted on Azure so I can download it by URL like so:

const geojsonLayer = new GeoJSONLayer({ url: "www.url.from.azure.com, copyright: "USGS Earthquakes", popupTemplate: template });

But it is quite big (~30 MB) and takes a while to load, so what I am trying to do is host it on Azure as a .zip file, download it, and then parse it into JSON. What I then want to do is feed it into the GeoJSONLayer so I can then display it. Is there anyway to do this?

I already have the download a zip file, unzip and parse as a JSON function ready so it would just be displaying the parsed JSON object.

You can take advantage of createObjectURL to create a URL object that you can set the GeoJSONLayer.url parameter to.

 function createGeoJSONURL(yourgeojson) { return URL.createObjectURL( new Blob([JSON.stringify(yourgeojson)], { type: "application/json" }) ); }
