Enable Message Editing and Deleting in Chat Rooms

[iammuho]

Implement functionality that allows users to edit or delete their messages in chat rooms. This will enhance user experience by allowing corrections and removals.

Requirements:
API Endpoints: Extend existing APIs to handle the editing and deleting of messages. The operations should be restricted to the original message author.

Sample API Extensions:

PUT /message/:messageID/edit
DELETE /message/:messageID/delete

• Event Types: Define event types to communicate message edit and delete actions.

EventTypeMessageEdited: Message has been edited.
EventTypeMessageDeleted: Message has been deleted.
WebSocket Notification: Notify room participants of any message edits or deletes via WebSockets.

• Database Changes: Ensure the edited message is updated in the database, and deleted messages are either removed or flagged as deleted, depending on your data retention policy.
• Client-Side Behavior: Update the frontend to reflect these changes in real-time without requiring a page reload. (Note: While this task focuses on the backend, the frontend will also need adjustments.)
• Testing: Include unit and integration tests to confirm that the feature functions as expected.

Success Criteria:

• Users should be able to edit their own messages.
• Users should be able to delete their own messages.
• All participants in the room should be notified of these actions in real-time.
