Question 1

How do I implement drag-and-drop file uploads in Angular with ng2-file-upload?

Accepted Answer

Use the ng2FileDrop directive on a div element and bind it to a FileUploader instance configured with your API URL. Handle events like onFileDrop to process dropped files, as demonstrated in the demo sources for a complete example.

Question 2

ng2-file-upload vs Angular Material file upload: which is better?

Accepted Answer

ng2-file-upload offers more flexibility for custom upload logic and backend integration, while Angular Material provides pre-styled components with design consistency. Choose based on whether you prioritize control over upload behavior or visual design out-of-the-box.

Question 3

How to set custom headers like Authorization in ng2-file-upload?

Accepted Answer

Initialize the FileUploader with the authToken property, e.g., new FileUploader({url: URL, authToken: 'Bearer token'}). This automatically adds the Authorization header to upload requests, as specified in the API documentation.

Question 4

Is ng2-file-upload compatible with Angular 12 or higher?

Accepted Answer

The library was built for Angular 2, and while it might work with newer versions, there's no official support for Angular 12+. Check the GitHub repository for updates or community forks, as compatibility may require manual adjustments.

Question 5

How can I track upload progress with ng2-file-upload?

Accepted Answer

The FileUploader provides event hooks for progress tracking. Subscribe to these events in your component to update UI elements like progress bars, referencing the demo for implementation details on handling file upload progress.

Question 6

Does ng2-file-upload support chunked or resumable uploads?

Accepted Answer

No, ng2-file-upload does not natively support chunked or resumable uploads. It focuses on standard file uploads with configurable parameters, so for advanced features, you'd need to extend it or use additional libraries.
