The combination of different ArcGIS products is extremely powerful, particularly when building geospatial web applications. However, sometimes there are instances where you might not have access to an ArcGIS Server or other ArcGIS offerings when tasked with building an application. This presentation will highlight the power of the ArcGIS API 4.x for JavaScript with GeoJSON data using the GeoJSONLayer class to satisfy a hybrid geospatial architecture requirement. This approach allows for fast and extensible ArcGIS JavaScript map rendering for client applications even when the required architecture does not allow for an ArcGIS Server or ArcGIS Online to serve the data. -------------------------------------------------------------------------------------------------------------------------- Follow us on Social Media!
