This is a schematic for adding File Handling support to an Angular PWA project. Run the schematic with the Angular CLI:

ng add @fugu-angular/file-handling --project <project-name>

Executing the command mentioned above will perform the following actions:

1. Adds required dependencies to your project.
2. Adds the file_handling property to the manifest.webmanifest file. If you do not have a manifest, run ng add @angular/pwa first.
3. Adds the necessary media types and file extensions to the manifest.
4. Provides a LaunchQueue service for responding to app launches.

See Let installed web applications be file handlers for more information.
