import { loadModule } from "@3ddv/dvm";

var input_options = {
    container: "container-id"
};

loadModule("map_viewer", input_options)
    .then(function(viewer) {
        console.log(`Module '${viewer.getModuleName()}' initialized:`, viewer);
    })
    .catch(function(err) {
        console.error(err);
    });

Input Options Object

The input options object contains all the basic configuration, including callbacks. The following main options may be included:

  • container (string|HTMLElement): HTML element or its id where the widget will be attached.
  • callbacks (Object) [optional]: You can see a list with the available callbacks here.
  • plugins (string[]) [optional]: List of plugins to be installed in this instance.
  • version (string) [optional]: You can specify the map_viewer version to be downloaded, usually latest or stable. stable by default.
  • client_id (string) [optional]: Use ONLY if MMC gives you a code to use. It may enable custom functionalities.
  • modern (boolean) [optional]: false to force the ES5 build download. If not specified or true it will check if the browser is compatible with ES2015+ build and download the compatible version.
  • shadowroot (boolean) [optional]: if you instantiate the module with shadowroot=true, it will attach the viewer to a ShadowRoot, and its styles to it, isolating it from the rest of the document. Global styles won't affect it. If 'container' is inside a ShadowRoot, shadowroot must be used.
  • aliases (boolean) [optional]: if you instantiate the module with aliases=true, the module will try to get a list of aliases for the ids of a certain venue. This might generate a network 403 error, but it won't break the application. These aliases will allow to use them when loading maps or using them as input with the API. Static Badge
