Code Review
This pull request introduces file upload functionality, which is a great step towards enabling richer, multimodal conversations. The changes are comprehensive, including database schema updates, new Vue components for handling uploads and displaying attachments, and integration with the AI model interaction logic. The code is well-structured. I have a couple of suggestions to improve type safety and robustness. Specifically, I've pointed out a place where using as any can be avoided by refining type definitions, and I've recommended a more robust method for generating unique client-side IDs.
| // If message has image attachments, build multimodal content | ||
| if (attachments && attachments.some(a => a.type === 'image')) { | ||
| return { | ||
| content: buildMultimodalContent(content, attachments) as any, |

The use of as any here indicates a type mismatch and bypasses TypeScript's type safety. The BaseMessage interface defines content as a string, but for multimodal messages, you're correctly passing an array of objects. To resolve this and restore type safety, the BaseMessage type definition should be updated to support multimodal content.
For example, in src/types/messages.ts, you could define a type for multimodal content parts and use a union type for BaseMessage.content:
// In src/types/messages.ts
export type MultimodalContentPart =
| { type: 'text'; text: string }
| { type: 'image'; image: string; mimeType?: string };
export type MultimodalContent = MultimodalContentPart[];
export interface BaseMessage {
content: string | MultimodalContent;
role: string;
attachments?: Attachment[];
}With this change, you can remove the as any cast, making the code more robust and maintainable.
content: buildMultimodalContent(content, attachments),
| function generateId(): string { | ||
| return `${Date.now()}-${Math.random().toString(36).substring(2, 9)}` | ||
| } |

While Date.now() + Math.random() is often sufficient for generating unique IDs on the client-side, it's not guaranteed to be unique, especially if files are processed very quickly. A more robust and modern approach is to use crypto.randomUUID(), which is specifically designed for generating cryptographically secure unique identifiers. It's widely supported in modern browsers and would be a better fit here.
function generateId(): string {
return crypto.randomUUID();
}
Adds file upload functionality to enable multimodal AI interactions and richer conversations.
