To upload files to CloudBase storage from a browser, initialize a shared CloudBase Web SDK app instance and call app.uploadFile with the selected file. This handles browser-side object upload without backend code.

Browser uploads to CloudBase fail with CORS errors when the exact browser origin, including host and port, is not added to CloudBase security domains. You must whitelist your caller origin in security domains to allow frontend upload flows.

Generate a temporary URL for a private CloudBase storage object by calling app.getTempFileURL with the returned file identifier. This safely resolves temporary access URLs for previewing private objects instead of fabricating public-looking links.

You can download and delete CloudBase files entirely in frontend Web app code by using the @cloudbase/js-sdk. Call app.downloadFile and app.deleteFile appropriately to manage private storage objects directly during Web app scenarios.

The best way to manage private storage objects in a Web app using CloudBase is using @cloudbase/js-sdk for browser-side operations. It reliably performs object storage upload, temporary URL generation, download, and deletion while respecting security-domain constraints.
