email-list.tsx

197d ago

ComposeButton.tsx: A component that provides email composition functionality with a dialog that can be minimized/maximized.
ThemeProvider.tsx: A simple wrapper around next-themes for theme management.
useIsMobile.tsx: A custom hook to detect if the viewport is mobile-sized.
useToast.ts: A toast notification system inspired by react-hot-toast.
email-detail-XN0sPExzdA27qCJEodPF4yNGbaIxhn.tsx: A component that displays the details of a selected email, including sender info, body content, and attachments.
email-list-DJj46bjtROTliUfy1npX0sqWSLZFdP.tsx: A component that displays a list of emails with search, selection, and star functionality.

The user is asking for backend code to support these frontend components, specifically mentioning "imapAttachment". This suggests they want to implement IMAP (Internet Message Access Protocol) functionality to connect to an email server, fetch emails, and handle attachments.

I'll need to create a backend implementation that can:

Connect to an IMAP server
Authenticate users
Fetch emails and their metadata
Download and handle attachments
Provide API endpoints for the frontend to interact with

This is a perfect use case for a Code Project with Next.js route handlers and server actions to implement the backend functionality. </Thinking>

I'll create a backend implementation for your email client that handles IMAP connections and email attachments. This will work with your existing frontend components.

How to Use This Backend

I've created a complete backend implementation for your email client that handles IMAP connections, email fetching, and attachment handling. Here's how it works:

Key Features

IMAP Connection: Connects to any IMAP server to fetch emails and attachments
Email Actions: Supports marking emails as read/unread, starring/unstarring, deleting, and moving emails
Attachment Handling: Downloads and processes email attachments
Email Sending: Sends emails via SMTP
Authentication: Verifies user credentials against the IMAP server

Integration with Your Frontend

The backend is designed to work seamlessly with your existing frontend components. I've updated the components to use the new backend services:

EmailClient: Main component that handles authentication and email management
EmailList: Displays emails fetched from the IMAP server
EmailDetail: Shows detailed email content with attachments
ComposeButton: Remains the same but now connects to the email sending API

Environment Variables

You'll need to set these environment variables on your Vercel deployment:

IMAP_HOST=imap.example.com
IMAP_PORT=993
SMTP_HOST=smtp.example.com
SMTP_PORT=587
SMTP_SECURE=true

Getting Started

Deploy this code to your Vercel project
Set the environment variables for your email servers
Users will be prompted to enter their email credentials when they first access the app
The credentials are used to authenticate with the IMAP server and are never stored

This implementation provides a secure, full-featured email client that works with any standard IMAP/SMTP email provider.
