View local GeoJSON (experimental)

Download example GeoJSON here. This example utilizes the File System Access API in newer Chrome and Edge browsers (see article and explanation). Instead of uploading the file to a server and reading it from there, it is accessed locally by the browser without any network transfer. In contrast to the File API, the file handle can be used to also write to the file (not implemented here). This example should be considered experimental, because window.showOpenFilePicker is not supported by all major browsers. See browser compatibility.
