Question 1

How to crop an image before upload with FileAPI?

Accepted Answer

Use the FileAPI.Image class methods like crop() and resize(). For example, FileAPI.Image(file).crop(640,480).get(callback) processes the image client-side, and you can then upload it via FileAPI.upload(). This reduces server load by handling edits in the browser.

Question 2

Does FileAPI support uploading large files in chunks?

Accepted Answer

Yes, FileAPI supports chunked file uploads with options like chunkSize and chunkUploadRetry, allowing reliable transfers of large files by breaking them into smaller parts. The server must handle chunked requests with specific HTTP headers and status codes, as detailed in the 'Server settings' section.

Question 3

FileAPI vs Dropzone.js: which is better for image uploads?

Accepted Answer

FileAPI offers more comprehensive client-side image processing (e.g., cropping, filters) and legacy browser support with Flash fallback, while Dropzone.js is simpler and more focused on drag-and-drop UI. Choose FileAPI if you need advanced preprocessing; Dropzone.js for a lightweight, modern approach.

Question 4

Can I use FileAPI with React or Vue?

Accepted Answer

Yes, but it requires manual integration since FileAPI is a vanilla JavaScript library. You can wrap its functions in React components or Vue directives, but there's no official framework support, so you'll need to manage state and lifecycle events yourself.

Question 5

Is FileAPI still maintained in 2024?

Accepted Answer

Based on the GitHub repository and changelog, the last updates were several years ago, so it may not be actively maintained. Check the repo for recent commits or issues before relying on it for new projects, as it might lack fixes for modern browser quirks.

Question 6

How to set up drag and drop file upload with FileAPI?

Accepted Answer

Use FileAPI.event.dnd() to attach handlers: FileAPI.event.dnd(el, hoverFn, dropFn) where dropFn receives the files list. For directory uploads in Chrome, use FileAPI.getDropFiles(). This is documented in the 'FileAPI.event.dnd' section with code examples.
