Pull Request: Implement File Handling Capabilities for chat0 #28
Conversation
|
@Prasannajaga is attempting to deploy a commit to the Harsh's projects Team on Vercel. A member of the Team first needs to authorize it. |
WalkthroughThe changes introduce file attachment support to the chat input component, enabling users to add files via drag-and-drop, paste, or file selection. New hooks and components manage file state and previews, and the message display now renders attached files. The Changes

Fix TextFilePreview receiving undefined fileList.
The TextFilePreview component is being passed undefined as the fileList prop, which will always render empty content. You need to pass the actual file data from the attachment.
The attachment object likely contains the file data or URL that should be used here. Consider either:
- Modifying
TextFilePreviewto accept a URL and fetch the content - Storing the actual File object in the attachment data structure
🤖 Prompt for AI Agents
In frontend/components/Message.tsx at line 83, the TextFilePreview component is
incorrectly receiving undefined for its fileList prop, causing it to render
empty content. To fix this, pass the actual file data from the attachment object
to the fileList prop. This may involve accessing the file or URL stored in the
attachment and providing it directly to TextFilePreview, or updating the
attachment structure to include the necessary file information.

Rendering arbitrary URLs in an iframe without validation could pose security risks. Consider implementing a whitelist of allowed domains or file types.
Add proper sandboxing attributes to the iframe and validate the URL source:

In frontend/components/Message.tsx at line 84, the iframe src attribute is set
directly from attachment.url without validation, posing a security risk. Fix
this by implementing a whitelist check to ensure the URL domain or file type is
allowed before rendering. Additionally, add sandbox attributes to the iframe
element to restrict its capabilities and enhance security.

In frontend/components/Message.tsx at line 75, the React key for the attachment
section is set to attachment.name, which may not be unique if multiple
attachments share the same name. Update the key to use a unique identifier for
each attachment, such as a combination of attachment name and a unique property
like an ID or index, to ensure stable and correct rendering by React.

with valid files. This prevents issues caused by large or unsupported files
being sent.

empty dependency array but uses fileUrls and fileList inside its callback, which

console.log statement that references them, allowing the empty array to be
correct.

Prevent memory leaks by revoking object URLs.
Object URLs created with URL.createObjectURL must be revoked to prevent memory leaks.
Store the URLs and revoke them when clearing or before creating new ones:

+ // Revoke previous URLs
+ fileUrls.forEach(url => URL.revokeObjectURL(url));

const urls = Array.from(files).map((file) => URL.createObjectURL(file));Also update clearFiles:

In frontend/hooks/useFileHandler.tsx at line 9, the code creates object URLs
with URL.createObjectURL but does not revoke them, causing potential memory
leaks. Modify the code to store the generated URLs in a variable or state, and
ensure that before creating new URLs or when clearing files, you call
URL.revokeObjectURL on each stored URL to release the memory. Also update the
clearFiles function to revoke all stored URLs before clearing them.

In frontend/hooks/useFileHandler.tsx at line 44, replace the deprecated
document.execCommand('insertText', false, text) with a modern approach. Use the
Clipboard API's navigator.clipboard.writeText(text) if you want to
programmatically copy text, or alternatively, allow the browser to handle text
insertion naturally without forcing it via execCommand. Adjust the code to avoid
using execCommand and adopt the Clipboard API or native input handling.

In frontend/hooks/useFileHandler.tsx around lines 8 to 17, add validation to the
processFiles function to check each file's size against a defined maximum limit
and ensure the total number of files does not exceed a set quantity limit. If
any file is too large or the number of files is too many, prevent further
processing and optionally provide feedback. Implement these checks before
creating object URLs and updating state to avoid performance issues.

this looks good, but we will first need a way to store these somewhere(S3 or somewhere), since we can't fill indexxed db with large files. |
