Angular project WebViewer integration issues

  • The WebViewer does not load properly and the HTML component is recursively re-rendered inside (see image below). How should I fix this?This error has likely occurred because WebViewer can't find it's library. Please make sure that you have done the following:
    • The library containing the webviewer.min.js file is not located inside the PROJ_PATH/src/app/ folder or any of its sub-folders
    • You have correctly added the path to webviewer.min.js to the scripts array under the build options array in angular.json
    • You have correctly added the path to the library in the assets array under the build options in angular.json

  • WebViewer having issues with progressive web application (PWA)

When using WebViewer as part of a PWA, make sure to include the path to WebViewer "lib" folder in your ngsw-config.json file. Also WebViewer needs to pass configuration information to it's workers. Make sure that you are not setting ignoreSearch to be true under cacheQueryOptions. So in your ngsw-config.json file

ignoreSearch default value is false so the ignoreSearch above is actually not needed. If a project requires ignoreSearch be to true for other resources, make sure to not set it to true for WebViewer's resources
